10.1.3
Authentication
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.

10.2 4-byte UID Operation
All MF1S70
3
yXDyy products are featuring a 4-byte NUID. This 4-byte NUID is stored in
block 0 of sector 0 as shown in
Figure 6
.
10.2.1
Anti-collision and Selection
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.
10.2.2
Authentication
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.
