What is NFC (Near Field Communication)?

Definition: NFC technology (Near Field Communication Technlogy)

NFC stands for "Near field communication" and is an RFID based form of contactless communication between devices like tablets smartphones and other devices that can have an NFC-/RFID reader integrated. Contactless communication allows a user to wave the smartphone over a NFC compatible device to send information without needing to touch the devices together or go through multiple steps setting up a connection.

The technology behind NFC allows a device, known as a reader, interrogator, or active device, to create a radio frequency waves that communicates with another NFC compatible device or NFC tags or NFC labels holding the information the reader wants. Passive devices, such as mounted NFC tags or for instance NFC labels in smart posters, store information and communicate with the NFC reader but do not actively read other devices. A smartphone with integrated NFC reader can have two functions: On the one hand it can operate as the passive NFC tag from that information can be retrieved and on the other it can operate as the active reading and writing device.

Both businesses and individuals can benefit from NFC technology (Near field communication). The NFC enabled smartphone has the potential to "empty" your purse of all its cards in the near future by simply emulating them virtualy.
