What is Near Field Communication (NFC) | How does it work

Near field communication (NFC)

Near field communication (NFC) is a wireless communication technology that uses various communication protocols to transfer data between two devices.

NFC technology uses short-range but high-frequency wireless signals to communicate and exchange data between two devices such as mobile devices and smartphones.

It has hassle-free pairing ability between two devices by just bringing them closer together or attached.



NFC technology is wireless, fast and easy to use. It uses radio-frequency identification (RFID) technology to exchange data between two NFC enables electronic devices.

Generally, for communications, we need an antenna. NFC also uses antennas. In mobiles devices, these NFC antennas are mostly attached to the back of the phone.
