Selected:
In this mode the Reader communicates only with the one, selected Transponder.
Before reading or writing data in selected mode, the UID of the Transponder must be
known. This is executed by sending at first the protocol "8.1.1. [0x01] Inventory". In a
second step the Transponder must be selected with the select command (see: 8.1.6.
[0x25] Select) which must include its UID.
The following chart will show the necessary steps for the communication with a Trans-
ponder in selected mode:
