NFC is a short-range wireless communication technology. It allows the exchange of data between two remote devices up to about 10 cm. Major credit card networks, like Visa, MasterCard, and American Express, back it. Therefore, the payment works much like our credit and payment cards but with the use of the mobile device. To pay at the cash desk of any store, it would be enough to put the phone near the reader to record the payment.

It is an extension of the RFID (Radio Frequency Identification) standard, which combines a smart card and a reader within a single device. Unlike QR-Codes and barcodes, RFID chips are not “read or decoded,” but real communication is engaged between devices. However, it is vital to ensure that the phone has built-in NFC technology and it is enabled for use (just as you activate your Bluetooth network).
