Depending on the chosen personalization option there are certain possibilities to perform 
anti-collision and selection. To bring the MIFARE Classic into the ACTIVE state according 
to ISO/IEC 14443-3, the following sequences are available.

Sequence 1:  ISO/IEC 14443-3 compliant anti-collision and selection using the cascade 

level 1 followed by the cascade level 2 SEL command

Sequence 2:  using cascade level 1 anti-collision and selection procedure followed by a 

Read command from block 0

Sequence 3:  ISO/IEC 14443-3 compliant anti-collision and selection using the cascade 

level 1 SEL command

Remark: The Read from Block 0 in Sequence 2 does not require a prior authentication to 
Sector 0 and is transmitted in plain data. For all other sequences, the readout from Block 
0 in Sector 0 is encrypted and requires an authentication to that sector.

Remark: The settings done with Personalize UID Usage do not change the ATQA coding.
