The standards were provided by the NFC Forum. NFC tags can be custom-encoded by their manufacturers or use the industry specifications. debit or credit card information, loyalty program data, personal identification numbers (PINs), contacts). Applications include secure personal data storage (e.g. They typically contain data (as of 2015 between 96 and 8,192 bytes) and are read-only in normal use, but may be rewritable. NFC tags are passive data stores which can be read, and under some circumstances written to, by an NFC device. NFC peer-to-peer Enables two NFC-enabled devices to communicate with each other to exchange information in an ad hoc fashion. See Host card emulation NFC reader/writer Enables NFC-enabled devices to read information stored on inexpensive NFC tags embedded in labels or smart posters.
NFC card emulation Enables NFC-enabled devices such as smartphones to act like smart cards, allowing users to perform transactions such as payment or ticketing. 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.Įvery active NFC device can work in one or more of three modes: These are standardized to NFC protocols, replacing proprietary technologies used by earlier systems.

NFC-enabled portable devices can be provided with application software, for example to read electronic tags or make payments when connected to an NFC-compliant system. This interface can be used for parameterization of the component as well. This connection can be used to exchange data (such as process data and maintenance and service information) between the devices. Two NFC-capable devices are connected via a point-to-point contact over a distance of 0 to 2 cm.
Near-field communication (NFC) describes a technology which can be used for contactless exchange of data over short distances.
