NFC (Near Field Communication)
Near-field communication (NFC) is a short-range wireless connectivity technology that uses magnetic field induction to enable communication between devices when they're touched together or brought within a few centimeters of each other. It builds on and extends the work of existing ecosystems and standards around radio frequency ID tags (RFID). NFC extends RFID and contactless capabilities with more dynamic features enabled by modern smartphones.
