For it is RFID CARD much closer than we think . Telefónica , Visa and La Caixa are conducting a pilot project that could revolutionize the world of in-store payments through NFC .
There are actually two types of mobile payments , the main difference lies in the proximity of the phone to the payment terminal ( POS ) . On the one hand you can transact , shop online or transfer money through mobile phone remotely ; otherwise you can make proximity payments , known as contactless . This second type of payment requires that the mobile device is near the terminal payment ( the typical machine with merchants that accept payment by credit card ) so that both devices will get closer the transaction.
But not all phones and all terminals are ready for this technology. Actually technologies proximity or contactless ( contactless ) are the union of two distinct but complementary technologies : smart cards and RFID . RFID and Smart Card Technology
Smart cards rfid inlay ( smart cards , chip card , or integrated circuit card ICC ) are those which, due to an integrated circuit can perform basic processes . For example, a SIM card is also a Smart Card. In turn, the radio frequency identification technology ( RFID ) is based on the electronic tags . These tags allow data storage , and a reader or a wireless transmitter captures that information through a radio channel .
