Near Field Communication (NFC) is a set of protocols that enable communication between two devices when placed in close proximity, using NFC Data Exchange Format (NDEF) messages.
NFC is designed to be a secure form of data exchange, and an NFC device is capable of being both an NFC reader and an NFC tag. This unique feature allows NFC devices to communicate
peer-to-peer. It can be used to perform automatic configurations, like pairing a printer (or other peripherals) to a PDA by Bluetooth; automatic connection to Wireless networks, and unlike barcodes, NFC tags don’t need to be scanned.
In Kalipso, you can use NFC to interface with any device or tag that supports this type of communications.
