NFC
Near Field Communications
NFC is a short range, standards based wireless connectivity technology based on RFID which uses magnetic field induction to enable communication between electronic devices in close proximity. NFC operates in the standard unlicensed 13.56MHz frequency band (plus 847.5KHz) over a distance of approximately 20cm. To date, it supports data rates of 106Kbps, 212Kbps and 424Kbps although higher data rates are expected in the future.
