10.1.3 Authentication
10.2.1 Anti-collision and Selection
10.2.2 Authentication
10.2 4-byte UID Operation
Table 15.
During the authentication process, 4-byte of the UID are passed on to the MIFARE Classic
Authenticate command of the contactless reader IC. Depending on the activation
sequence, those 4-byte are chosen differently.
Table 16.
All MF1S703yXDyy products are featuring a 4-byte NUID. This 4-byte NUID is stored in
block 0 of sector 0 as shown in
The anti-collision and selection process for the product variants featuring 4-byte NUIDs is
done according to ISO/IEC 14443-3 Type A using cascade level 1 only.
The input parameter to the MIFARE Classic Authenticate command is the full 4-byte UID
retrieved during the anti-collision procedure. This is the same as for the activation
Sequence 3 in the 7-byte UID variant.
