1.2. ISO15693 Host Commands
The ISO Host Commands provides the exchange of data between a host and Transponders via the
Reader as long as the Transponder remains in the detection range of the Reader.
Note:
During the writing of data on a Transponder, it must be ensured that the Transponder is lo-
cated within the detection range of the Reader during the entire process. If the Transponder is
removed from the detection range of the Reader during a writing process, this will cause a loss
of data.
The Reader distinguishes between three different modes:
Addressed mode:
Before reading or writing data in addressed mode, the UID of the Transponder must be
known. This is executed by sending the protocol
located within the detection range of the Reader at that time, it answers with its UID. For all
following read- / write orders the Transponder must be addressed with its correct UID.
The following chart will show the necessary steps for the communication with a Transponder
in addressed mode:
