the tag ID is 64 bits.
Make sure that the first two bits have the correct values,
depending on the tag ID length.
0409 INVALID ADDR The RFID reader received a command to write to an invalid
address in the tag data address space. Make sure that the address
specified is within the scope of the tag data address space.
