NFC (Near field communication)
NFC stands for “near field communication”. It provides short range communication between compatible devices. In an NFC communication, there is one transmitting device and the other device receives the signal. Smartphone are the most common implementations of active NFC devices. The NFC also use radio waves to send information
The advantage of NFC over Bluetooth is the shorter set- up time. The connection between two NFC devices can be established under a 1/10 second. It provides much better security than the Bluetooth.
