Product Description
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 42, see "Single Write Words SW" on page 43, and see
"Memory Module for Tag Accesses to the "Memory Bank" MB" on page 52.
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 4.2.4)
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), and enhanced read special read-only code (ES). See
"Single Read Special Read-Only Code SS" on page 40, see "Single Write Special Read-Only
Code SP" on page 41, and see "Enhanced Read Special Read-Only Code ES" on page 41.
Bank 10: TID
The segment Bank 10 contains the tag identifier (TID), consisting of the part number and
optional serial number of the tag. This data is permanently stored without being changed. The
first byte denotes the class of the tag with E0
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
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 40 and see "Enhanced Read Read-Only Code EF" on page 40)
Bank 11: User Memory
Segment Bank 11 contains an area to which the user has free access. This size of this area
depends on the chip type, or the area may not be present.
The data in segment Bank 11 is addressed via the single read words (SR), single write words
(SW), enhanced read words (ER), and enhanced write words (EW) commands. (see "Single
Read Words SR" on page 42, see "Single Write Words SW" on page 43, see "Enhanced Read
Words ER" on page 42, and see "Enhanced Write Words EW" on page 43)
