NFC stands for near field communication, which is a wireless communication technology that allows devices to exchange data or perform transactions when they are within a few centimeters of each other. NFC uses radio frequency identification (RFID) to create a short-range wireless connection. NFC is commonly used for contactless payments, smart cards, and digital wallets.
