NFC, short for Near Field Communication, is a short range wireless RFID technology that makes use of interacting electromagnetic radio fields instead of the typical direct radio transmissions used by technologies such as Bluetooth. It is meant for applications where a physical touch, or close to it, is required in order to maintain security. NFC is planned for use in mobile phones for, among other things, payment, in conjunction with an electronic wallet

2. NearField
Communication • Near field communication (NFC), is a
method of contactless communication
between two NFC enabled devices
(Smartphone, tablets etc.)
• NFC forum ensures strict standards to NFC
device manufactures to make
communication secured and easy
• NFC operates in two modes
– Active mode : Can read/send data from/to other
NFC enabled device
– Passive mode : Can not read data from other
device (SmartPosters)
• NFC is based on RFID technology
– Magnetic field induction technology
– Operates on Unlicensed Frequency
• Specification
– Works from touching distance to 4cms (Some
devices up to 10cms)

3. History • In 2004 Nokia, Philips and Sony jointly
established the NFC forum
• In 2006, NFC tags specification released
• In 2006, Nokia released first NFC enabled
mobile (Nokia 6131)
• In 2009, NFC forum released Peer-to-Per
standards to exchange contact, URL etc.
• In 2010 Samsung releases Nexus S with
NFC capability (Android)
• In 2010, city of Nice in South France
enables some of the services like
transportation, tourism and student services
using NFC
• In 2011, RIM was certified by MasterCard
worldwide to use NFC for transaction
(PayPass)
• In 2011, Google demonstrated GoogleSource: http://en.wikipedia.org/wiki/Near_field_communication
