Anticollision Command Definitions
Commands in this section are arranged in order by the hexadecimal code in the command byte.
REQB / WUPB Polling Commands [$05]
The REQB / WUPB command is used to search for PICCs in the RF field. The command and response are ISO/IEC
14443-3:2001 compliant.
The “Request B” (REQB) and “Wake-Up B” (WUPB) commands are used to probe the RF field for Type B PICCs as the
first step in the anticollision process. The response to an REQB or WUPB command is the “Answer to Request B”
(ATQB). PICCs in the Active State are not permitted to answer this command.
