Command ID 'z': Select (Select Data Carrier in Multi-tag Mode)
►
In the Multi-tag Mode, the
Select
command selects a single data carrier from within a data
carrier population. A data carrier that is located in the active read/write zone of the antenna is
accessed and selected directly based on its EPC or its TID and is then available for further
processing.
For the BIS V only ECP or TID can be selected, selecting USER data is not possible. The EPC
and TID are output in reverse order with leading zeros.
