Bank 00: Password Management
The segment
Bank 00
contains the password management information,
comprising the access password and the kill password. The read/write head
manages the kill password with the standard read/write commands SW and SR.
The access password is not supported. see "Single Read Words SR" on page 33
and see "Single Write Words SW" on page 34.
Bank 01: UII/EPC
In addition to the Unique Item Identifier (UII), the segment
Bank 01
contains a
calculated checksum CRC (Cyclic Redundancy Check) for verifying data on the
tag and the protocol control (PC) area. The PC area contains:
■
The length of the UII
■
The Application Family Identifier (AFI) box
■
A bit switch that shows whether the UII contains an EPC sequence of
numbers in accordance with ISO (see chapter 4.2.6)
■
A bit switch that shows whether data is stored in segment bank 11 (if
present)
The data is addressed via the following commands: single read special read-only
code (SS), single write special read-only code (SP), enhanced read special read-
only code (ES), and enhanced write special read-only code (EP). (see "Single
Read Special Read-Only Code SS" on page 31, see "Single Write Special Read-
Only Code SP" on page 32, see "Enhanced Read Special Read-Only Code ES"
on page 32, and see "Enhanced Write Special Read-Only Code EP" on page 33)
Bank 10: TID
The segment
Bank 10
contains the tag identifier (TID), consisting of the part
number and serial number of the tag. This data is permanently stored without
being changed. The first byte denotes the class of the tag with E0
hex
, E2
hex
, or
E3
hex
. The rest of the TID depends on the class, and can be derived from
standard ISO/IEC 18000-63.
Example:
All tags with the class EPC Gen 2 (ISO/IEC 18000-63) are marked with E2
hex
. The
TID is comprised as follows:
■
4 bytes: part number of the tag
• 1 byte: identifier
• 12 bits: tag mask designer identifier (MDID)
• 12 bits: tag model number (TMN), defined by the manufacturer:
■
4 or 8 bytes: serial number of the tag
Depending on the manufacturer, the serial numbers do not have to be
unique or may even be omitted.
The data in segment
Bank 10
can be output via the single read read-only code
(SF) and enhanced read read-only code (EF) commands. (see "Single Read
Read-Only Code SF" on page 31 and see "Enhanced Read Read-Only Code EF"
on page 31)
