3.3.12. GetSnr_HT2_C
This command selects a HITAG 2 transponder in Crypto Mode. With this selection the transpon-
der is prepared for read and write commands in HITAG 2 Crypto Mode.
After the command has been executed, the reader module returns the serial number and the con-
tent of the configbyte.
When a transponder in Password Mode receives the command "GetSnr_HT2_C", only the serial
number and the status message "Password RWD error" are returned.
If the transponder is set in one of the public modes, it can only be selected within 2.56 ms after
reset (entering the RF field or activating the RF field).
