NFC(Near Field Communication)

What is NFC(Near Field Communication) is all about ?

Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. Present and anticipated applications include contact-less transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi. Communication is also possible between an NFC device and an un-powered NFC chip, called a "tag".

NFC standards cover communications protocols and data exchange formats, and are based on existing radio-frequency identification (RFID) standards including ISO/IEC 14443 and FeliCa. The standards include ISO/IEC 18092 and those defined by the NFC Forum, which was founded in 2004 by Nokia, Philips and Sony, and now has more than 160 members. The Forum also promotes NFC and certifies device compliance.
NFC builds upon Radio-frequency identification (RFID) systems by allowing two-way communication between endpoints, where earlier systems such as contact-less smart cards were one-way only. Since un-powered NFC "tags" can also be read by NFC devices, it is also capable of replacing earlier one-way applications.

Bluetooth and WiFi connections

NFC offers a low-speed connection with extremely simple setup, and could be used to bootstrap more capable wireless connections. It could, for example, replace the pairing step of establishing Bluetooth connections or the configuration of Wi-Fi networks.

Social Networking

NFC can be used in social networking situations, such as sharing contacts, photos, videos or files and entering multiplayer mobile games.
