4.3.8 Various Settings
This section describes the parameter settings and operation specifications based on ISO/IEC14443 TypeB for
this RFID.
4.3.8.1 AFI (Application Family Identifier)
Figure 4-22 shows the format of AFI (Application Family Identifier). The value of AFI is set in the system area
AFI.
AFI is a parameter specified by the REQB command. The response operation to REQB command in this
RFID is shown in Table 4-18. For information about the setting values for AFI, see ISO/IEC14443-3.

Responds regardless of the system area AFI setting.
Responds when the value Y of the upper 4 bits of the
REQB command's AFI is matched.
Responds when the value Y of the lower 4 bits of the
REQB command's AFI is matched.
Responds only when the setting value of the REQB
command's AFI matches the value specified in the system
area AFI.
4.3.8.2 PUPI (Pseudo-Unique PICC Identifier)
Figure 4-23 shows the format of PUPI (Pseudo-Unique PICC Identifier). PUPI is an identifier of PICC
(Proximity IC Card). The value of PUPI is set in the lower 4 bytes of the system area IDM.
