2.2. ISO15693 Host Commands
The ISO Host Commands provide 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
located within the detection range of the Reader during the entire process. If the Tran-
sponder is removed from 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 has to be
known. This is executed by sending the protocol “
If a Transponder
is 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 Tran-
sponder in addressed mode:
