NFC

NFC (Near Field Communication) is a short-range wireless technology that enables the exchange of data between devices. It operates in the 13.56 MHz frequency range and can be used for various purposes, including contactless payments, data transfer, and access control.

NFC technology establishes a wireless connection between two devices when they are placed close to one another, typically a few centimeters or inches apart. The technology uses a combination of magnetic fields and radio waves to transmit data between devices.
