7.1.1. [0x01] Inventory
This command reads the UID of all Transponders inside the antenna field. If the Reader has de-
tected a new Transponder, the Transponder will be automatically set in the quiet state by the
Reader. In this state the Transponder does not send back a response for the next inventory com-
mand.
The Transponder sends back a response every time:
if the Transponder has left the antenna and reentered the antenna field or
if a 6.7. [0x69] RF Reset command was send to the Reader or
if the Persistence Reset Time has expired.
