What’s NFC (Close to Area Connection)?
NFC stands for Close to Area Communication which is a set of short-range wi-fi connection expertise of about 4cm distance or much less. With NFC, you may share small quantity of knowledge between an NFC tag and an Android-powered machine, or between two Android-powered gadgets.
NFC supplies the next diploma of safety than Bluetooth and makes NFC appropriate for crowded areas the place correlating a sign with its transmitting bodily machine (and by extension, its consumer) would possibly in any other case show not possible. NFC may also work when one of many gadgets isn’t powered by a battery.
Android-powered gadgets with NFC can help three important modes of operation on the similar time:
- Reader and author mode
- Permitting the NFC machine to alternate knowledge with different NFC friends; this operation mode is utilized by Android Beam. And it is usually referred to as P2P mode.
- Card emulation mode which permits the NFC machine itself to behave as an NFC card. The emulated NFC card can then be accessed by an exterior NFC reader, resembling an NFC point-of-sale terminal.
