This standard copies the commands and memory structure of the UHF standards ISO/IEC 18000-63. The HF standard is less complex as the UHF standards. For example, ISO/IEC18000-3 Mode 3 defines only a subset of 5 error codes compared to 14 error codes defined in ISO/IEC 18000-63.
All definitions from B.3 apply.
Memory structure may be reduced compared to ISO/IEC 18000-63. Reserved memory (MB 00) may be absent, when no passwords are needed. UII memory (MB 01) may be as small as 32 bits. Maximum size is 464 bits. TID memory (MB 10) has at least an 8-bit ISO/IEC 15963 allocation class identifier and further identifying information for unique identification. User memory (MB 11) is optional. For the operation of the tag it is the same memory structure as ISO/IEC 18000-63.
