What is NFC and how does it work?
NFC, or Near Field Communication, is a technology that allows devices to communicate with each other when they are in close proximity. It works by using a small antenna to transmit and receive data between devices. NFC is commonly used for mobile payments, data transfer, and reading NFC tags. NFC tags are small chips that can be embedded in various objects, such as stickers, posters, or even clothing, and can store small amounts of data. When an NFC-enabled device is brought close to an NFC tag, it can read the data stored on the tag and perform a specific action.
The technology behind NFC is based on radio-frequency identification (RFID) and works at a frequency of 13.56 MHz. NFC devices can operate in two modes: active and passive. In active mode, the device generates its own RF field and can communicate with other active NFC devices. In passive mode, the device uses the RF field generated by another device to communicate. NFC tags are typically passive, meaning they do not generate their own RF field and rely on the device to power the communication. This makes NFC tags very low power and allows them to be used in a wide range of applications.
