Writing to encrypted areas of the HITAG 1 transponder with this command leads to a status
“NOTAG error“ and the transponder is reset.
To write to encrypted areas of the transponders use the command “WritePage_HT1_C“.

Upon completion of the write command, a “Read after Write“ procedure should be carried out in
