Near Field Communication
Near Field Communication (NFC) is a short-range wireless communication technology that enables the exchange of data between devices over a distance of a few centimeters. NFC operates at 13.56 MHz and can transfer data at a rate of up to 424 kbps. It is a contactless technology that allows two devices to communicate with each other when they are brought close together. NFC is used in a variety of applications, including mobile payments, access control, data transfer, and identification. NFC-enabled devices can read and write to NFC tags, which are small, passive devices that can store data and transmit it to an NFC-enabled device. NFC technology is considered to be secure and reliable, as it requires physical proximity between the devices for communication to occur.
