RFID Tag IC Command and Response
All commands listed above are described in details in ISO/IEC15693-3 documents. Some of thefrequent used commands are discussed here for quick reference.

Protocol concept
A9212-A RFID tag IC follows ISO-15693 standard’s simplex communication protocol scheme.
Reader needs to issue appropriate command before A9212-A RFID tag IC will respond with thecorresponding data packet.

A9212-A RFID tag IC is designed base upon the one command one

action structure.

Each reader command and each tag reponse packet are contained in a frame. The frame isdelimited by frame delimiters SOF (Start of Frame) and EOF (End of Frame).

Each reader

command consists of the following fields:․
