NFC is a high frequency, short-range wireless communication technology that allows data to be sent between devices up to a distance of around 10 cm.
NFC integrates a smartcard and reader interface into a single device, improving upon the current proximity card standard (RFID). It enables users to pay bills wirelessly, transmit material between digital devices with ease, and even use their mobile as an electronic trip ticket on public transportation’s already-existing contactless infrastructure.
The faster setup time of NFC over Bluetooth is a major benefit. Unlike laborious setups for Bluetooth device identification, two NFC devices connect instantly (less than 1/10 of a second).
NFC offers a greater level of security than Bluetooth because of its shorter range, which also makes it appropriate for busy spaces where it could be difficult to correlate a signal with the actual device that is delivering it (and, consequently, with its user).
When one of the devices—such as a contactless smart credit card or an off-duty phone—is not powered by a battery, NFC can still function.
