Description: The ANTICOLLISION and SELECT commands are based on the same

command code. They differ only in the Parameter byte. This byte is per definition 70h in

case of SELECT. NTAG203F accepts these commands in the Ready1 state only. The

response is part 1 of the UID. Even with incorrect CRC value, the SELECT command will

be fully functional.
