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.[1] NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections.[2] Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a 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.

The NFC Forum has helped define and promote the technology, setting standards for certifying device compliance.[3][4] Secure communications are available by applying encryption algorithms as is done for credit cards[5] and if they fit the criteria for being considered a personal area network.[6]
