Mallorca, Spain- August 21, 2016. A customer paying using contactless credit cards payment system. In a demonstration for the press of the benefits of the card. Contactless payment systems are credit cards and debit cards, key fobs, smart cards or other devices, including smartphones and other mobile devices, that use radio-frequency identification RFID or near field communication NFC for making secure payments. The embedded chip and antenna enable consumers to wave their card, fob, or handheld device over a reader at the point of sale terminal. Contactless payments are made in close physical proximity; they are usually distinguished from mobile payments which can also take place on mobile phones, but mobile payments use broad-area cellular or WiFi networks and do not involve close physical proximity. Some suppliers claim that transactions can be almost twice as fast as a conventional cash, credit, or debit card purchase. Because no signature or PIN verification is typically required, contactless purchases are typically limited to small value sales. Lack of authentication provides a window during which fraudulent purchases can be made.
