NFC stands for Near Field Communication. It is a set of short-range wireless communication protocols that enable two electronic devices to communicate when they are within about 4 centimeters (1.5 inches) of each other
. NFC operates at a frequency of 13.56 MHz and supports data transfer rates ranging from 106 to 424 kbit/s
. NFC technology is commonly used for secure transactions like contactless payments (e.g., Apple Pay, Google Pay), ticketing, data exchange, and device pairing such as connecting Bluetooth headphones
. It works through inductive coupling between two electromagnetic coils, where one device generates a radio frequency field that can power a passive target device or tag
. In summary, NFC is a wireless communication standard designed for very close-range interactions between devices, enabling secure and simple data exchange
