near-field communication
Also known as NFC, near field communication
radio communication established between devices by bringing them into proximity
AI overview
Near-field communication is a type of radio connection that works when two devices are brought close together. It matters because it enables convenient wireless interactions over short distances, like contactless payments or data sharing between phones.

The secure element chip, an NFC chip that contains data such as the Secure Element identifier (SEID) for secure transactions. This chip is commonly found in smartphones and other NFC devices.
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 cm (1+1⁄2 in) or less. NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on an NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio-frequency ISM band, compliant with the ISO/IEC 18000-3 air-interface standard at data rates ranging from 106 to 848 kbit/s.
