Near Field Communication (NFC)
Near Field Communication (NFC) is a short-range wireless communication technology that allows devices to exchange data over a distance of a few centimetres.
All NFC communication is based on the ISO/IEC 18092 standard.
The nRF52 series MCUs have a near field communication tag peripheral called NFCT
. This peripheral can be used to implement an NFC tag. It supports NFC-A listen mode operation at 13.56MHz and a bitrate of 106kbps.1
NDEF
NDEF (NFC Data Exchange Format) is a standard for exchanging data between NFC devices. It is a binary format structured in messages. Each message can contain one or more records. Each record contains metadata (e.g. record type, length) and the payload.2
