Near Field Communication

NFC is the acronym for Near Field Communication.

What is Near Field Communication?

A short-range wireless technology that allows communication between two devices when they are brought close to each other, typically within a few centimeters.

NFC works through electromagnetic induction. The technology involves two components, a passive tag or label that stores data and an active device, such as a smartphone or tablet, that can read or write data to the tag.

When an active device, such as a smartphone, is placed near an NFC tag, the tag sends a signal containing information, which is received by the device’s NFC reader. This communication is bidirectional, which means the active device can also send data to the NFC tag.

NFC is commonly used for contactless payments, allowing users to pay for goods and services by simply tapping their phone or smart card on a compatible terminal. It is also used for other applications, such as data transfer between devices, pairing of Bluetooth devices, and access control to buildings or events. NFC technology is becoming increasingly popular and is expected to be integrated into more devices and applications in the future.
