The standards were provided by the NFC Forum. Like other " proximity card" technologies, NFC is based on inductive coupling between two so-called antennas present on NFC-enabled devices-for example a smartphone and a printer-communicating in one or both directions, using a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band using the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 424 kbit/s. NFC offers a low-speed connection through a simple setup that can be used to bootstrap more capable wireless connections. Near-field communication ( NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 cm (1.57 in) or less. This chip is commonly found in smartphones and other NFC devices. The Secure Element chip, an NFC chip that contains data such as the Secure Element identifier (SEID) for secure transactions.
