What is a dealer identification number
Mobile payment glossary
1 Glossary Mobile Payment Subscription Trap = is a trap on a website in which the consumer is to be tricked into inadvertently entering into a contract for a subscription. This is achieved in a targeted manner that the costs are only mentioned hidden in the general terms and conditions or in the margins, so that the surfer is not aware of something that is legally relevant. Even if, from a legal point of view, no contract is concluded and does not have to be paid, some consumers can still be put under pressure and pay. Adult / Age verification system (AVS) = (Age verification system). System that is supposed to check whether the user is old enough to use the offer. If pages offer content that is harmful to minors, they must ensure that minors cannot access it. There are companies that offer external age verification systems so that the websites themselves do not have to check the age, but rather the users log in to the age verification process once and thereby gain access to all partner companies. In terms of data protection law, this is the better alternative, as the websites actually used do not receive any data about their users. Android = is an operating system (from Google) for mobile devices such as smartphones and tablet computers. Android is software with freely accessible source code (open source); it is controlled via the touchscreen of the smartphone and other additional software and hardware (voice control is also possible). 75% of smartphones are now operated with Android. The current version 4.4 (released on) is also called KitKat. It is critical to see that Android gives Google the ability to access smartphones and delete software and that the software is open source, but restricts the user's freedom to use programs from other manufacturers. Application (app) = (English application (software)) is additional software for smartphones and tablet computers, which are offered in large numbers from different platforms (so-called app stores). In contrast to system programs, such application programs have a directly applicable benefit for the owner. These little utilities have some useful, but also entertaining functions (e.g. image editing programs, shopping lists or apps from news channels). However, the downloading of apps should not be done carelessly, because apps can also contain malware, especially if they come from external websites and not from the tested platforms of the major providers. Augmented Reality = describes an electronic extended sensory perception of reality. With the help of a high-performance smartphone, the picture of reality can be expanded with further functions through the smartphone. (E.g. filming the soccer game with a smartphone, which automatically generates additional information in the image, such as the distance from a free kick) Bank Identifier Code (BIC) = is an international identification number that is assigned to banks so that they can be identified. This identification number replaces the national bank codes and consists of 8-11 digits.
2 Barcode = is a barcode that can be processed optically and electronically. The code consists of bars of different thicknesses with different gaps that can be read by a scanner. The barcode was first introduced in Germany, and this technology has developed further since then; there are now even 4-dimensional barcodes. This method can also be used for payment with a smartphone. A barcode can be generated on the smartphone and read in by the scanner at the checkout (e.g. Edeka offers this smartphone payment option). Bill-it-easy = is a payment service for paid content on websites on the Internet. No additional registration is required for this payment method; When the page is called up, the user receives a pop-up notification that the content is subject to a charge. If the user accepts this, he will receive an additional invoice on the provider's invoice to cover the costs for the website. Bluetooth = is used for short distances (between 10 and 100m) for data transmission between devices via radio technology (WPAN). Bluetooth chips are standard equipment in cell phones and tablets. Bluetooth is used primarily for the wireless connection of small devices such as headsets, which, unlike infrared, does not require visual contact. Button solution = a solution to the problems of subscription traps is called through the amendment of 312g II, III, IV BGB, through which the European consumer rights directive should be implemented. According to this, the online retailer must order the label on the button for online contracts that come about through a button (= button) or attach a very (!) Similar label. Furthermore, all essential information about the goods and price must be immediately in front of the button. Click-Through-Rate = (also called AdClick Rate) is the ratio of the clicks of an advertisement displayed on a website to the number of page visitors. This means that if an advertisement is displayed 100 times and clicked once, the advertisement has a click-through rate of 1%. Most click-through rates, however, are closer to 0.1%. Cookies = are text files (in HTTP) with data about visited websites, which are automatically saved on the computer. These are not hidden or secret like viruses are, because their storage is intentional. By storing cookies, the website should load faster and passwords do not have to be re-entered each time you visit. However, they can also be misused to create user profiles by logging surfing behavior (so-called tracking cookies). With the help of such user profiles, personalized advertising offers should be made possible, which should generate higher profits. Couponing = is part of a marketing strategy that aims to attract customers with discount stamps. This couponing system is not a new invention (coupons wedding in the 1950s), but is now also being used for mobile payment, as coupons available online can be used through the smartphone and thus an advantage of cheaper shopping is to be made possible . Cybersquatter = (Cyber squatter, also called domain grabbing) is a person who reserves domain names on the Internet, but does not use them himself. Cybersquatters buy domain names with important names in the hopes of selling them to a big company. Dialer = is software that enables the computer to dial in via a specific Internet provider. This is done using the telephone number, which can also be a chargeable service number, so that the content of the page can be calculated per minute. Or an 0800 number enables free online shopping on an Internet shopping website. Download-to-own = is a business model in which videos (including other software) can be downloaded for a fee and which has a permanent right of use, i.e. the video does not become unusable after a certain period of time. The word (to) own means to belong, but if the user does not acquire ownership of the content, he is not allowed to reproduce it. The counterpart to this business model for videos is the pay-per-view process.
3 E-banking = is the electronic execution of banking transactions via the computer or smartphone. The customer can use the device to connect to the network of his bank and thus exercise account functions - print bank statements, check account balance, etc. E-Commerce (electronical) = is the technical term for electronic business transactions. This includes, above all, the online trade in goods; Online auctions (e.g. ebay) and online shops (e.g. Amazon) can now be found in large numbers on the Internet and generate billions in sales. E-Commerce (everywhere) = is an artificial change from the original meaning of E-Commerce. With the proliferation of mobile devices, it is no longer only possible to shop electronically, but also from many places. Everywhere commerce is the complete realization of multichannel marketing (informing consumers about offers in as many ways as possible). Not only in the store is advertised and bought, but also on the home computer and now even on the go on the mobile phone. E-fulfillment process = is the name of the entire process that is necessary to fully deliver the order and accompanying information to the customer and, if necessary, to collect it again. Electronic bill presentment and payment (EBPP) refers to payment systems in which the customer receives the invoice electronically. This is often done with s with text file attachments (direct billing variant); but can go so far as to offer separate and distinct payment platforms (Consolidator variant). s with invoices have to meet strict legal requirements. E-payment = (English electronic payment) refers to payment transactions or payment processing with electronic aids. Electronic payment processes are intended to be a convenient alternative to cash payments, as you only have to carry a card, smartphone or the like with you. E-money is defined in the European E-Money Directive. The largest share of cashless payment transactions makes up by a large margin (approx. 80%) the transfer. Electronic Point of Sale (EPOS) = is the place where payment and electronic registration of the inventory are made. Payment transactions are saved there so that they can be evaluated later. In spite of the electronic registration of receipt and sale of goods, manual inventories have to be carried out regularly in order to compare the target electronic stock with the actual stock. ewallet = (also called cyberwallet) is a payment option on the Internet. Here, money is loaded onto an electronic wallet using the prepaid method. This top-up can be made via advance transfer / ATM / credit card payment. The user can then pay with the e-wallet up to the top-up amount, which has the advantage (as is generally the case with prepaid) that only the top-up money is at risk. If a fraudster becomes aware of the secret identification data of the ewallet, only the topped up credit can be used. Factory Unlock = Smartphones can be equipped with a SIM lock, which means that they can only be used with a specific SIM card. This is to prevent other providers from being used for the cell phone. This is completely legal in Germany; But there are also countries in which this is prohibited under competition law in order to prevent forced commitments (e.g. Italy, Belgium, ...). The smartphones are correspondingly more expensive there. But you can buy a cell phone in these countries in order to be able to use another provider here.
4 Firewall = is a security system that is intended to protect against access to computer networks or individual computers. This is hardware and / or software that is connected between the computer and the public network. Firewalls are preinstalled on many operating systems and must be updated regularly; But there are also paid programs that are supposed to provide special protection. Flat rate = is a flat rate for telecommunication services (telephony and internet connection). The first telephone flat rate for the German landline network was offered by Arcor in 2004 and the first mobile flat rates were offered in the following year. The first internet flat rate was offered as early as 1998, but had to be discontinued due to a lack of profitability. Freeware = is free software from the Internet. This may be copied and reproduced, but this must not hide the fact that the software is still protected by copyright. Global Area Network (GAN) = is a network that is connected over the entire earth. The Internet, for example, is a GAN because it theoretically connects the whole world. A satellite or fiber optic network is usually required to create a global area network. Global Positioning System (GPS) = (English. Global Positioning System) is a global navigation satellite system for position determination and time measurement. A GPS device only receives signals, but does not send any, which explains its original use for the military. Since the GPS signal is relatively weak, it only works in the open air with a full signal; the signal can be disturbed even under trees. The GPS system is also used for mobile payment; GPS is used for the Touch and Travel mobile payment offer from DeutscheBahn and BVG to determine entry and exit. Google Wallet = is an electronic payment system offered by Google. An NFC-enabled smartphone can thus be used to pay. You also need a Google account and a credit card. GoogleWallet can also be used to pay in the company's own Play Store. Hotspot = (English hot point) is a wireless public access location to the Internet. This can be made available free of charge, as offered by some cafés and even promote individual communities as a project, or it can be paid for. Hypertext Markup Language (HTML) = (Hypertext Markup Language) is a design language that is intended to structure the content of documents. It is a pure text file that is used to design and structure websites. However, HTML does not determine the form of rendering for the surfer; the display by different web browsers may vary. HyperText Transfer Protocol Secure (Https) = is used for encryption / authentication of communication between web server and browser. Websites can be authenticated by established authentication authorities, which then assign an individual encryption code to them. The encryption is carried out by TLS (= Transport Layer Security; formerly SLL). Surfers should always try to open websites with https first, because many sites offer both a secure https connection and an http version (because https is more powerful for providers). International Bank Account Number (IBAN) = is an international account number (with a maximum of 34 digits), which is made up of country-specific as well as bank-specific number arrangements. It is necessary to make transfers within the EU. Furthermore, the IBAN will completely replace the previous account numbers for transfers.
5 International Mobile Equipment Identity (IMEI) = is a 15-digit serial number that is assigned to every GSM and UMTS terminal. This means that each device can be clearly assigned. The number can be used to block a stolen cell phone so that it cannot be used with another SIM card (hackers can bypass this, however). International Mobile Subscriber Identity (IMSI) = is a 15-digit serial number that is assigned to each network subscriber in the GSM / UMTS network through its SIM card. Each IMSI number only exists once in the world for an individual SIM card. It can be used to identify a SIM card. Infrared = denotes the signal transmission in the invisible infrared range; Both devices, receiver and transmitter, need an infrared eye for this. The two devices must not be far from each other and must have visual contact. This is also the disadvantage compared to WiFi or Bluetooth, so that infrared was no longer integrated in cell phones. Only recently, thanks to the multifunctionality of smartphones, has this been reinstalled in order to give the smartphone the additional function of TV control. ios = is an operating system for Apple smartphones that was released together with the iphone in 2007. The current version of is version 7. The operating system is used by around 15% of smartphones, making it the second most popular smartphone operating system. IP address (Internet protocol) = are addresses in computer networks that are assigned to devices that are connected to the Internet. This means that the devices can be addressed so that data can be sent to them. A distinction is made between permanently assigned (static) and repeatedly assigned (dynamic) IP addresses. Dynamic IP addresses were used because there would not have been enough IP addresses for all users; There are now enough addresses available, but static allocation is still mostly dispensed with in order to guarantee anonymity and data protection on the Internet. IP telephony = (also called Voice over IP) is telephony over the Internet network. However, due to its changing allocation, the IP must not be confused with a conventional fixed telephone address, since the IP address is always changed. A connection is established by a server that connects the telephone partners with one another. Around 8 million people in Germany use IP telephony. izettle = is a payment method using smartphones (especially iphone). Payment can be made using a card reader for the smartphone. To do this, the payment provider has to register on the company's website and after receiving the reader, he can accept payments on his smartphone.According to its own statements, the company is primarily aimed at small and medium-sized companies. Location based service (LBS) are services that provide the user with specific information and services through information about the position (e.g. bus stop finder). Such services are often carried out with the help of smartphones, as these can determine the position (using UMTS or GPS). LBS is used, for example, in DeutscheBahn's touch-and-travel payment system. If you place great value on data protection, you should switch these functions off, at least when they are not being used, so that no exact movement profiles can be created. In this context, the term Geoslavery was coined. Long Term Standard (LTE) = is a cellular standard for data transmission and is also referred to as 4G (4th generation). LTE is intended to replace UMTS (3G) as it achieves much faster download rates. However, a complete replacement of UMTS has not yet been implemented, as the network still has to be expanded for this. Macropayment system = are the payment methods that involve more than small sums, ie payments from 5-10 and credit cards from 30. Different methods are used for payment (advance payment, invoice, Internet payment services e.g. PayPal), whereby the importance of the Internet - Payment services in this area are growing. The opposite of macropayment is micro-payment.
6 Malware = is a combination of malus (Latin for bad) and software. This term is understood to mean all computer programs that deliberately bring about harmful functions (but not merely faulty ones). Most of them are familiar with computer viruses and computer worms, as well as Trojans, key loggers and backdoor programs and have already been affected by them. Malicious programs also exist for smartphones and cell phones, albeit not as pronounced as for computers. With cell phones, these usually lead to the automatic dialing of chargeable numbers or SMS. Value-added services = are a kind of forerunners of mobile payment. These are chargeable offers or services that are carried out via regular telecommunications and billed to them. Chargeable service numbers are still offered today (0190 numbers: eg competitions, support, information, ...) Micropayment system = are the payment methods that involve small sums, ie payments up to 5. Especially on the Internet, online - Vendors sell products with very small amounts, such as ringtones, newspaper articles, apps, music and films. Payment methods such as direct debit and credit card payments are unsuitable here because they are too expensive and the payment costs quickly exceed the value of the goods. General payment options for this are prepayment systems with prepaid credit or PayPal, but there are also numerous special payment options such as the mobile payment apps from various providers. The opposite of micropayment is macropayment. Merchant Identification Number (MID) = is a number that is assigned to every merchant who accepts credit cards so that the bank can identify them. mpass = is a mobile payment system using NFC stickers. After setting up an mpass account, mpass sends an NFC sticker that can be attached to the mobile phone, but also to other objects (advertised by attaching it to the smartphone). The automatic payment up to 25 euros is made by holding the smartphone with the sticker on the cash register terminal at a distance of up to 4 cm; In the case of higher amounts, a PIN is also required at the cash register. Billing takes place via direct debit or bank transfer; The mpass app should also enable the expenditure to be checked. Mobile Added Values (MAV) are the informational added values of mobile payment resulting from 4 properties: omnipresence, context sensitivity, telemetry function (= measurement function), identification option. Mobile banking = is the processing of banking transactions with the help of mobile phones and thus a form of e-banking. Mobile Commerce (MC) = is the mobile payment option and a synonym for the widespread term mobile payment. For this reason, see also under mobile payment Mobile devices = devices are electronic devices that are connected to a public telecommunication network. Mobile refers to the devices that, due to their low weight and portability, can be used mobile, i.e. can be taken with you - a smartphone, for example, is a mobile device because it is small and handy, and the user can therefore be connected to telecommunication networks at different locations Has. Mobile payment (M-Payment) = is cashless payment with a mobile device. In some cases, however, the term mobile payment should be narrower and only refer to payment with the smartphone / cell phone (but sometimes also delimited as handypayment) and other mobile devices such as e.g. do not include the laptop. The payment processes with the smartphone are mostly in the area of micropayments, i.e. in the range of only a few euros.
7 Mobile Originated Billing (MO Billing) = is a billing variant for Premium SMS. The customer sends a short message to the service provider from his cell phone. Such an SMS usually costs between 29ct and 4.99. This process is used, for example, when ordering ring tones, mobile phone logos and mobile phone games. Mobile wallet = symbolizes the smartphone in its role as a new payment medium. Mobile Terminated Billing (MT-Billing) = is a billing variant for premium SMS in which the customer pays for each message received. This takes place e.g. when used in subscription services and messaging services. Mobile ticketing (M-ticketing) = is the ordering of tickets (entrance tickets, train tickets, bus travel tickets, ...) using mobile devices. The cards are often loaded directly onto the device after payment and can be printed out from there or canceled directly from the smartphone. Nandroid = is a back-up for the Android operating system. The settings (system settings as well as apps and memory statuses) are saved and can be restored in the same way later. If a virus has infected the system, the problem can be quickly remedied by the back-up. Near Field Communication (NFC) = is a signal that only sends at close range (a few centimeters). Many smartphones, including credit, debit and customer cards, have an integrated NFC reception, which is why it is also used for mobile payment. No user input is required, so that fast payments are possible; as a result, it is used especially in the checkout area. Netbook = is a smaller and lighter notebook and is intended to be an inexpensive alternative, but there are limitations in terms of equipment and performance. Online auction = is an auction that runs over the Internet, the most important provider is ebay. It is important to mention that online auctions are not auctions in the sense of the German Civil Code and therefore 156 BGB is not applicable. The highest bidder at the end of the bidding period receives the goods and has to pay the agreed price in return. Paid content = is paid digital content that is offered by online service providers. Payment is usually confirmed with one click and the content becomes available. Paid content has only a low level of acceptance in Germany. Another method of payment is social payment, where you will be asked for a voluntary donation. Paid inclusion = is a marketing strategy in which a search engine operator is paid money so that their own website is included in the search list. Paid Placement = the search engine operator is paid money so that their own website gets the best possible position in the list of results. Users of the search engine do not find out that this result has landed so high up through payment and not through the frequency of clicks. Payleven = is a card reader provider that enables credit card payments between private individuals using a chip + pin reader and a free app. The reader is connected to the tablet or smartphone via a Bluetooth wireless connection. The costs are entered on the smartphone and the paying person enters the credit card into the reader.
8 Payment Solution = denotes the entirety of cashless payment options in the e-commerce sector. These include: invoice, prepayment, cash on delivery, direct debit and credit card. PayPal = (English payment friend) is an online payment system from PayPal, which has been a subsidiary of ebay since 2002. It is mainly used to settle medium and small amounts (e.g. buying and selling online). The advantages of this payment method are the relatively fast and secure payment. Furthermore, no transfer of the bank details to the seller is necessary, which leads to better data protection. Payment Card Industry Data Security Standard (PCI DSS) = is a set of rules with security requirements for credit card transaction processing. Credit card companies are checked by VISA for compliance with the regulations. Pay-per-view = is a business model in which the user has to pay a fee in order to be able to see the film online. However, the user does not have the option of permanent use and cannot download the film. Pay-per-view is therefore comparable to a virtual video store. The opposite of pay-per-view is the download-to-own business model. Point of sale (POS) is the cash register, where, among other things, the devices for credit card or EC card payments are located in the shop. Manipulation at the point of sale can lead to the spying of the card data or the PIN. NFC stickers in particular could be stuck over inconspicuously with false stickers. When it comes to online payment, one also speaks of EPOS, the electronic point of sale. Premium Multimedia Messaging Service (Premium-MMS) = is a message that enables multimedia content to be sent. In addition to text, images and videos can also be sent; MMS therefore offers more options than SMS. Every year 0.36 million MMS are sent in Germany. Premium MMS are more expensive than normal MMS and offer additional services. Premium Short Message Service (Premium-SMS) = is a kind of forerunner of mobile payment in the field of cell phones. It is a text message with a maximum of 160 characters, 157 million SMS are sent annually in Germany. Premium SMS are much more expensive (up to 4.99). They are used to bill for services through the mobile phone. Billing takes place via the mobile phone bill. Premium SMS are also often used for fraud. Prepaid = (English prepaid) is a credit account that is topped up with money through prepayment. Use of services is paid for via this credit account. The advantage here is that only the amount of money that has already been loaded is at risk of fraud and the payment data does not have to be transmitted to the contractual partner. Payment Service Provider (PSP) = are companies that give e-business companies the opportunity to offer payment methods over the Internet. A PSP can offer different types of payment, such as credit card, electronic direct debit, purchase on account and prepayment, but also e-payment methods such as e.g. PayPal. Source code = is a text of a computer program written in programming language. This is human readable and can be called up on websites by right-clicking on a page and displaying the source code. If the source code of a program can be called up, it is an open source software. This is to enable other programmers to work with the program.
9 QR codes (Quick Response) = (quick response) is a two-dimensional code consisting of a square matrix of black and white dots. Smartphones can read and interpret this pattern with their camera, which is why the QR code is sometimes used for mobile payments. However, freely accessible codes on posters should be used with caution, because the QR codes can be covered with codes that redirect to websites with malware. Radio-frequency identification (RFID) = (electromagnetic wave identification) people or objects can be automatically identified and localized with the help of electromagnetic waves. A transponder attached to the object and a reader are required for this. This procedure is also used to identify the DB-Bahn's mobile payment service. Re-targeting = is an online marketing technique in which the surfer's website visit (especially an online shop) is saved with a cookie so that the surfer is recognized when he opens the page of an advertising partner. A product that he has already viewed on another website is then displayed in an advertising banner there. Indecisive buyers should be encouraged to make a final purchase. This marketing strategy is to be disapproved of under data protection law, as interest profiles of the surfer are created without his consent. Rogue Software = (rogue software) is software that acts like antispyware and pretends to the user that there are various malware programs on the computer / mobile phone that need to be removed. In most cases, a link is then made to a page on which a paid antivirus program from the same provider is advertised in order to entice the user into making a purchase. Root = is a user account with extensive access rights to the smartphone, including its system settings. The user is allowed to make changes to the system; this can be an advantage, but it can also cause great damage to inexperienced users. If malware is transferred to the smartphone, it can cause much greater damage to a root account. Semantic targeting = is an online marketing method in which the content or meanings of a website can be read in order to place advertising content in the banners that match the content and thus appeal to the customer with a higher probability. Smartphone = is a multifunctional mobile phone. Typical features are comparatively large and high-resolution screens, alphanumeric keyboards and / or touch screens. Many devices also have digital cameras and other additional functions that can also be purchased in the form of small programs (so-called apps). Snarfing = (from snort to sniff out and scarf devour) is the attack on devices in wireless networks, usually by exploiting security holes. Devices connected to hotspots are particularly at risk. Spam = is an undesirable one that is often used for aggressive advertising or even fraud. In some cases, attempts are made to find out bank details through fraudulent s (so-called phishing). Subscriber Identity Module (SIM card) = (subscriber identity module) is a small chip card that is inserted into a cell phone. The mobile phone number and the ISMI are stored on the SIM card. Other data is also stored on it, such as the last SMS messages. Support = is the support of the user in case of problems with the goods or the technology (hardware / software). Employees can usually be reached by telephone via a hotline; larger companies often have their own department dedicated to solving problems for their customers.
10 Symbian = is an operating system that was mainly used for Nokia mobile phones. However, since Nokia switched to the Windows operating system in 2011, Symbian will only play a minor role. Tablet computer = is a portable, flat computer, particularly lightweight, with a touchscreen. Unlike a notebook, a tablet does not have a fold-out keyboard. In terms of performance, however, it is mostly more similar to a smartphone. Third-party billing = is the processing of mobile payments via a third-party provider. Payments are transferred to a payment provider who then settles them with the merchant. Payment providers also take care of unfulfilled payments, possible reminders and the involvement of debt collection companies. Touchscreen = is a combined input and output device in which the program of a technical device is controlled directly by touching the screen. Control is therefore carried out using a finger or a pointer pen. Trusted Shops = is a company that issues certificates for online shops. A certificate from Trusted Shops should prove the seriousness, reliability and good data protection of the online retailer. Typosquatting = buying domain names that are very similar to a well-known website (theoretical example: googel.de instead of google.de). They hope to make a lot of money with advertising, as it often happens that surfers find themselves on such a page due to a typing error. In some cases, deceptively real copies are also displayed on these pages in order to gain access to surfers' data (so-called phishing). U-Commerce = is the short form for ubiquitous commerce (English ubiquitous trade) and describes the uninterrupted and ubiquitous communication and trade between entrepreneurs and customers. Mobile devices (especially smartphones) play an important technical role. Universal Mobile Telecommunications System (UMTS) = is a cellular standard for data transmission and is also referred to as 3G (3rd generation).Due to the high bandwidth, the technology enables large amounts of data to be transmitted quickly and has replaced GSM (Global System for Mobile Communications; 2G) because it has a higher data transmission rate. In the next few years, UMTS will probably be completely replaced by LTE (4G). User generated content is web content that does not come from the provider of a website, but was created by internet users. There is a lot of user-generated content, especially in blogs and communities, and also on the YouTube video platform. Consumer contract = is a contract that is concluded between a consumer and an entrepreneur (B2C = Business to Consumer). In such contracts, some consumer protection regulations apply, which often result from European directives. VeriSign = is a US company that offers certification for websites. VeriSign also issues certificates to websites for the SSL encryption method used on HTTPS pages. Virtual Terminal = (also called EPOS) the payment provider provides the seller with a special website that is used as a till, the merchant saves himself from having his own till system.
11 What sapp = is a program for smartphones to exchange messages, photos and videos. The data is sent over the Internet in order to enable a free or significantly cheaper alternative to the previous SMS. What sapp has repeatedly received criticism from data protectionists. Wi-Fi = is often used as a synonym for WiFi, but this is not entirely accurate. Because WiFi refers to the network, while WiFi refers to the radio standard. However, since this mostly coincides, this small difference is not noticeable. The Wi-Fi seal is only awarded to members, but non-members can also provide WiFi. This means that even without a Wi-Fi seal, it can be a WLan-enabled device. Windows Phone 8 = is an operating system for smartphones from Microsoft. However, the operating system only has a market share of around 4% and is therefore lagging behind in third place among smartphone operating systems. Wireless Local Area Network (Wlan) = wireless internet access in a local radio network. Compared to a Wpan connection, a Wlan connection has greater transmission power, a greater range and, as a rule, a higher data transmission rate. Wireless local loop (Wll) = (English. Wireless subscriber line) is a directional radio connection that is used instead of a subscriber line. In sparsely populated areas this is used to set up a telephone connection. Wireless Personal Area Network (Wpan) = (English wireless personal network) is a short-range radio technology. This covers distances in the range from 0.2 to 50 m.
