Near Field Communication Technology

What is Near Field Communication Technology?

Near Field Communication (NFC) is a short-range wireless communication technology that allows devices to exchange data when they are in close proximity, typically within a range of 4 centimeters or less. Operating on radio-frequency identification (RFID) principles, NFC enables two-way communication between devices, making it distinct from other wireless technologies like Bluetooth or Wi-Fi. NFC is widely used in applications such as contactless payments, access control, data sharing, and device pairing.

NFC operates in three modes:

1. Reader/Writer Mode: One device reads or writes data to an NFC tag.
2. Peer-to-Peer Mode: Two NFC-enabled devices exchange data directly.
3. Card Emulation Mode: An NFC device acts as a contactless card for payments or access control.
