Near Field Communication (NFC) is a wireless technology that allows high-speed data transfer between NFC-enabled devices over short distances. NFC replaces paper tickets, allows fast sharing of media and information, and makes device pairing easy. Common uses of NFC include contactless payments, electronic identity cards, event tickets, information sharing between devices, and connecting devices to Bluetooth or Wi-Fi. NFC has a range of up to 20 cm and is less power intensive than Bluetooth.
