Unique identifier (UID)
Members of the SRT512 family are uniquely identified by a 64-bit unique identifier (UID).
This is used for addressing each SRT512 device uniquely after the anticollision loop. The
UID complies with ISO/IEC 15963 and ISO/IEC 7816-6. It is a read-only code, and
comprises (as summarized in

SRT512
Reader
an 8-bit prefix, with the most significant bits set to D0h
an 8-bit IC manufacturer code (ISO/IEC 7816-6/AM1) set to 02h (for
STMicroelectronics)
a 6-bit IC code set to 00 1100b = 12d for SRT512
a 42-bit unique serial number
It is in the low-power state.
It is in Ready state.
It shows highest impedance with respect to the reader antenna field.
It will not respond to any command except Initiate().
