The munication protocol plies with parts 2 and 3 of the ISO/IEC 14443A specification. Anti-collision A9211B’s anti-collision function allows multiple RFID tags operating in reader’s magnetic field simultaneously. The anti-collision function enables the detection and operation of A9211B when other A9211B equipped tags are also present. Cascaded Unique Identification Number A9211B’s unique identification number (UID) is 7 bytes long and supports cascade level-2 format according to ISO / IEC 14443-3. p2 of 15 Ver. 1.0 A9211B ISO/IEC 14443A RFID TAG IC Pin...
