NFC functions on the principle of sending information over radio waves just like Bluetooth and WiFi, and all manner of other wireless signals.  

Near Field Communication is another standard for wireless data transitions, meaning that there are specifications which devices have to adhere to in order to communicate with each other properly.

The technology used in NFC is based on older RFID (Radio-frequency identification) ideas, which uses electromagnetic induction in order to transmit information.
