The Application Family Identifier (AFI) is used to select the family and sub-family of cards which the PCD
is targeting. Only PICCs with a matching AFI code are permitted to answer an REQB or WUPB
command. Table 5 describes the AFI matching criteria. An AFI of $00 activates all Type B PICCs.
AFI matching criteria for polling commands received by the PICC.
The PARAM byte is used to send two parameters to the PICC. The parameter “N”, which assigns the
number of anticollision slots, and the REQB / WUPB selection bit.
Definition of the PARAM byte in the REQB/WUPB command.
Coding of “N”, the number of anticollision slots, in the PARAM byte.
Coding of the REQB / WUPB selection bit in the PARAM byte.
Communication error detection bytes.
