       . NEAR FIELD COMMUNICATION.

NFC is basically-----> NEAR FIELD COMMUNICATION

As the name suggests, its a very short distant communication between two devices through an intermediate.

In today's daily life it has been the most important part of our life as short distance(4.5cm around). we can connect two devises so that we can communicate.

ACTUAL DEFINITION  OF **NFC**

-----------------------------------------------------

Near Field Communication (NFC) is a short-range wireless connectivity standard that uses magnetic field induction to enable communication between devices when they're touched together, or brought within a few centimeters of each other. Jointly developed by Philips and Sony, the standard specifies a way for the devices to establish a peer-to-peer (P2P) network to exchange data. After the P2P network has been configured, another wireless communication technology, such as Bluetooth or Wi-Fi, can be used for longer range communication or for transferring larger amounts of data.

NOW LETS GET HOW NFC ACTUALLY  WORKS?

-----------------------------------------------------------------------

NFC works on the principle of sending information over radio waves. Near Field Communication is another standard for wireless data transitions. This means that devices must adhere to certain specifications in order to communicate with each other properly. The technology used in NFC is based on older RFID (Radio-frequency identification) ideas, which used electromagnetic induction in order to transmit information. I hope you are getting it?

1)BLUETOOTH

2)XENDER

3)HOTSPOT

4)WI_FI

4)TELECOM.
