9.4 ATQA and SAK responses
For details on the type identification procedure please refer to Ref. 2.
The MF1S70yyX/V1 answers to a REQA or WUPA command with the ATQA value
shown in Table 11 and to a Select CL1 command (CL2 for the 7-byte UID variant) with
the SAK value shown in Table 12.

Remark: The ATQA coding in bits 7 and 8 indicate the UID size according to ISO/IEC
14443 independent from the settings of the UID usage.
Remark: The bit numbering in the ISO/IEC 14443 starts with LSBit = bit 1, but not LSBit
= bit 0. So one byte counts bit 1 to 8 instead of bit 0 to 7.
10 UID Options and Handling
The MF1S70yyX/V1 product family offers two delivery options for the UID which is stored
in block 0 of sector 0.
• 7-byte UID
• 4-byte NUID (Non-Unique ID)
This section describes the MIFARE Classic MF1S70yyX/V1 operation when using one of
the 2 UID options with respect to card selection, authentication and personalization. See
also Ref. 6 for details on how to handle UIDs and NUIDs with MIFARE Classic products.
10.1 7-byte UID Operation
All MF1S70yXDyy products are featuring a 7-byte UID. This 7-byte UID is stored in block
0 of sector 0 as shown in Figure 7. The behaviour during anti-collision, selection and
authentication can be configured during personalization for this UID variant.
10.1.1 Personalization Options
The 7-byte UID variants of the MF1S70yyX/V1 can be operated with four different
functionalities, denoted as UIDFn (UID Functionality n).

1. UIDF0: anti-collision and selection with the double size UID according to ISO/IEC
14443-3
2. UIDF1: anti-collision and selection with the double size UID according to ISO/IEC
14443-3 and optional usage of a selection process shortcut
3. UIDF2: anti-collision and selection with a single size random ID according to ISO/IEC
14443-3
4. UIDF3: anti-collision and selection with a single size NUID according to ISO/IEC
14443-3 where the NUID is calculated out of the 7-byte UID
The anti-collision and selection procedure and the implications on the authentication
process are detailed in Section 10.1.2 and Section 10.1.3.
The default configuration at delivery is option 1 which enables the ISO/IEC 14443-3
compliant anti-collision and selection. This configuration can be changed using the
‘Personalize UID Usage’ command. The execution of this command requires an
authentication to sector 0. Once this command has been issued and accepted by the
PICC, the configuration is automatically locked. A subsequently issued ‘Personalize UID
Usage’ command is not executed and a NAK is replied by the PICC.
Remark: As the configuration is changeable at delivery, it is strongly recommended to
send this command at personalization of the card to prevent unwanted changes in the
field. This should also be done if the default configuration is used.
Remark: The configuration becomes effective only after PICC unselect or PICC field
reset.

10.1.2 Anti-collision and Selection
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.

UID Functionality Available Activation Sequences
UIDF0 Sequence 1
UIDF1 Sequence 1, Sequence 2
UIDF2 Sequence 3
UIDF3 Sequence 3
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. In general, the input parameter to the
MIFARE Classic Authenticate command is the set of 4 bytes retrieved during the last
cascade level from the ISO/IEC 14443-3 Type A anticollision.
Table 16. Input parameter to MIFARE Classic Authenticate
UID Functionality Input to MIFARE Classic Authenticate Command
Sequence 1 CL2 bytes (UID3...UID6)
Sequence 2 CL1 bytes (CT, UID0...UID2)
Sequence 3 4-byte NUID/RID (UID0...UID3)
10.2 4-byte UID Operation
All MF1S703yXDyy products are featuring a 4-byte NUID. This 4-byte NUID is stored in
block 0 of sector 0 as shown in Figure 6.
