NFC - Contactless Data Exchange Over Short Distances

Near Field Communication (NFC) is a data transmission standard based on RFID technology. The frequency is set at 13.56 MHz. NFC data exchange takes place over short distances of a few centimeters with a maximum data transmission rate of 424 kbps.

NFC is needed for data exchange between two briefly paired devices. This includes, for example, communication between a credit card and a payment terminal, or between a smartphone and an NFC label.

NFC technology is used for authentication, access control, contactless payment and consumer IOT. Access credentials are transferred between a smartphone and a reader, enabling mobile contactless authentication. NFC chips embedded in products contain a stored URL that is transmitted and provides customers with additional product information and proof of authenticity. NFC-enabled employee badges grant access to IT systems and secure areas.
