NFC, or Near Field Communication, is a wireless communication technology that allows data exchange between devices within 10 cm of each other. It uses 13.56 MHz radio frequency identification technology to enable easy target selection by holding two NFC-enabled devices close together. NFC can transmit data at rates up to 424 kilobits per second and supports various operation modes including card emulation, reader/writer, and peer-to-peer communication between devices. Potential uses of NFC include contactless payments, electronic tickets, and data sharing between devices like phones.
