NFC stands for Near Field Communication, a short-range wireless communication technology that allows two electronic devices to exchange data when they are close together (within a distance of 4 cm or less). It is a widely used contactless communication method that is widely used in smartphones, smart cards, payment systems and access control devices.
What the letters in NFC stand for
N – Near Field: Communication can be carried out at a very short distance, ensuring a secure and accurate data exchange.
F – Field: refers to the electromagnetic field generated between devices.
C – Communication: Two-way data exchange, including authentication, payment or pairing.
Today, NFC technology is built into almost all modern smartphones, including iPhones and Android devices. It enables users to:
Tap to pay (e.g. Apple Pay, Google Pay)
Read NFC tags on posters or packaging
Unlock NFC access control
Store and share NFC digital business cards
How does NFC work?
NFC operates at a frequency of 13.56 MHz and allows data to be exchanged between an initiator (such as a smartphone) and a target (such as an NFC tag or card). The initiator creates an RF field and the target responds - either passively (without its own power source) or actively (requiring power).
