Contactless chip cards are standard credit cards with an embedded contactless chip. Optionally, a MagStripe<\/a> is also provided\u00a0for backwards compatibility.\u00a0These cards require\u00a0no physical contact with the point-of-sale (POS) terminal. To make a payment, the consumer holds the contactless card in close proximity (less than 2-4 inches) to the merchant<\/a> POS terminal and the payment account information is communicated wirelessly\u00a0via\u00a0Radio Frequency (RF).<\/p>\n Radio frequency waves are the frequencies within the electromagnetic spectrum associated with radio wave propagation. Many wireless communications technologies are based on RF, including radio, television, mobile phones, wireless networks and now, contactless payment cards and devices. Don’t confuse this RF with RFID technologies used in manufacturing, shipping and object tracking. Those are\u00a0designed to operate over long ranges (in the order of 25 feet) and typically don’t have built in security and privacy. On the other hand, the contactless cards that are used for payments are desgined to operate at a short range and come built-in with security and cryptography capabilities.<\/p>\n In the image above, the logo marked on the right hand side represents the\u00a0universal contactless symbol. If you see this logo on your credit card, you can be sure that it supports\u00a0contactless payments. Similarly, POS devices that support contactless payments\u00a0prominently display the same logo to advertise their capability for the same.<\/p>\n Typically, when you make a payment with contactless cards, you are not required to enter a PIN or\u00a0autograph your signature. This is intentional because, one of the most touted value-add features provided by a contactless card is\u00a0fast checkout times. Consequently, they are sometimes also referred to as In the context of mobile payments, when you use a Since mobile phones are way more powerful than a plastic card, they can hold as many cards as you\u00a0want and the NFC chip will be able to simulate\u00a0any or all of them. This essentially turns your mobile phone into a virtual mobile wallet. Now you know where the concept of Mobile wallets origintated from.<\/p>\n \n Welcome to the Mobile payments FAQ and\u00a0not so FAQ<\/a>\u00a0series\u00a0and you are on FAQ\u00a0#7.\u00a0The idea behind this series is to\u00a0share and learn as much as possible about the field of mobile payments.\u00a0If you like, you can read all of the FAQs on the Mobile Payments<\/a>\u00a0category or by visiting the Table of contents<\/a> page.<\/p>\n","protected":false},"excerpt":{"rendered":" What is a Contactless Chip Card?

The NFC controller chip\u00a0inside the mobile device is put into card-emulation<\/code> mode. In this mode, the NFC chip behaves like a Contactless chip card thereby\u00a0transforming your mobile phone\u00a0into a contactless credit card.<\/p>\nMobile Payments Blog Series<\/h4>\n
