![]() ![]() 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.
