5.2. ConfigCard - Data Structure
A ConfigCard is accepted by the Reader if all Identifier's and checksums are correct and the AFI is
set to value 0x38.
The configuration is stored on the Transponder according to the following structure.

ConfigCard Identifier:
The ConfigCard Identifier is one of the identification characteristics of a valid ConfigCard
and is formatted as follows:
Byte 1 2 3 4
Content UID_CRC 'C'
(0x43)
'2'
(0x32)
UID_CRC:
CRC16 checksum calculated above the 8 byte Transponder UID (see 5.2.1.
CRC16 Calculation Algorithm for details)
AFI (Application Family Identifier) according ISO 15693-3 = 0x38
A second identifier of a valid ConfigCard is the AFI which is stored in the AFI byte of the
ConfigCard.
AFI most significant nibble = 3 (Identification)
AFI least significant nibble = 8 (Data storage)
ConfigData:
see 5.1. Configuration Parameter
CRC_CONFIG:
CRC16 Checksum calculated above ConfigCard Identifier and ConfigData. (see 5.2.1.
CRC16 Calculation Algorithm for details)
