3.7.10 TagAuthent
Carries out the single authentication procedure for HITAG 1 transponders (authentication of the
transponder). The authentication procedure is aborted after sending the transponder logdata.
Using -keyinfo- you can choose between Key/Logdata Set A and B.
This command can be used - e.g. - to check if Keys and Logdata in the transponder and the
read/write device are the same. ("Check, if the transponder is member of the same `family´ as the
read/write device").
ATTENTION: You cannot use any Crypto commands after TagAuthent.
After this abbreviated authentication procedure the transponder can only be accessed using
GetSnr or the command HFReset.
