Tag Type Technical Specifications

The specifications for the NFC Forum Type 1/2/3/4/5 Tags provide the technical information needed to implement the reader/writer and associated control functionality of the NFC device to interact with the tags. The new TNEP 1.0 Candidate Specification supports the bi-directional exchange of NDEF messages based on the communication protocol used by the NFC Forum Tag devices of Type 2, 3, 4 and 5. The aim of these specifications is to define how NDEF messages are read from and written to NFC tags.
