These national transmission specifications for UHF such as frequency range, output and the status of
any national regulations can be obtained from the Internet at:
http://www.gs1.org/docs/epcglobal/UHF_Regulations.pdf
For further information please contact the relevant authorities in the country in which you wish to use
the UHF RFID system.
2.4
Approval of data carriers and read/write heads
The read/write heads mostly require an approval from a national regulation body, depending on the
specific national regulations (in Europe and India, however, no approval is required). A corresponding
approval of the data carriers is not required.
2.5
General information on the UHF data carriers
The UHF data carrier memory hierarchy is divided into four logical areas acc. to ISO 18000-6C (also
called domains) and can take several blocks – each block consisting of 2 bytes.
Domain 0 – reserved area: This bank includes (depending on the data carrier type) the passwords
for accessing the memory and for deactivating the data carrier. The passwords for deactivating are
stored in the memory addresses 00
hex
to 1F
hex
. The passwords for access are stored in the memory
addresses 20
hex
to 3F
hex
. Memory access is normally executed with special protocol commands.
Domain 1 – EPC (electronic product code) or UII (unique item identifier): This bank contains the es-
sential identification data of the transponder. The 16-bit checksum (CRC) is located in the first data
word (from address 00
hex
). The second data word (= 2 bytes) contains specific data carrier control
information (protocol control byte, from address 10
hex
). The actual data range of the UIIs starts at
address 20
hex
. The data carriers are identified within the
BL ident®
system via the first eight bytes of
the data range, i.e. from address 04
hex
to 0C
hex
.
Domain 2 – TID (tag identification): This bank contains one of three values for identifying the class
code (E0
hex
, E2
hex
or E3
hex
) in accordance with ISO/IEC 15963, contained in the memory addresses
00
hex
to 07
hex
. If the class ID is E0
hex
, the TID contains a 48-bit serial number.
The composite 64-bit data carrier ID is assigned once within all data carrier classes that are defined
in ISO/IEC 15963 and are write protected by the manufacturer. If the class ID is E2
hex
, the TID contains
a 12-bit data mask ID and a 12-bit data carrier model number defined by the manufacturer.
The use of memory addresses above 1F
hex
is defined in the EPCglobal data standards, Version 1.5
and higher. If the class ID is E3
hex
, the TID contains an 8-bit manufacturer ID, followed by a 2-byte
user memory for different data lengths, the 48-bit serial number, the 1-bit XTID and the 15-bit XTID
header data. The composite 80-bit data carrier ID is assigned once within all data carrier classes that
are defined in ISO/IEC 15963 and are write protected by the manufacturer.
Domain 3 – User area: This bank is optional and contains a memory area of varying size for use as
required by the user.
Attention
Possible damage to the data carriers!
Incorrect writing to the reserved area (bank address = 00) or to the first four bytes of the UII
memory (bank address = 01) of the data carrier memory may cause the data carrier to
permanently malfunction.
