SYMBOL DESCRIPTION
GSY Command “Get System Information”
GUID Command “Get UID”
SOF Start Of Frame
PCB Protocol Control Byte (see section ISO/IEC 14443 Block Transmission Protocol for details)
[CID]
The tag’s assigned card identifier (see section Network Function Commands for details). The brackets [ ]
indicate that the transmission of the CID depends on the Protocol Control Byte (PCB).
CRC-16 Transmission of an inverted CRC-16 (2 bytes) generated according to CRC16-CCITT.
EOF End Of Frame
IND Response indicator byte
IFLG Info Flags byte
UID The tag’s unique 8-byte identification number
DB Dummy byte
AFI Application Family Identifier byte
NBLK Number of Blocks byte (slave memory size indicator)
MBS Memory Block Size byte (slave memory block size)
ICR IC-Reference byte (slave chip revision)
