Product Description
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 33, see "Single Write Words
SW" on page 34, see "Enhanced Read Words ER" on page 34, and see
"Enhanced Write Words EW" on page 35)

Electronic Product Code (EPC)
The electronic product code is a unique identifier in the form of a sequence of
numbers. The number sequence has a set structure and a length of 64 bits, 80
bits, 96 bits, or longer (depending on the EPC Ident number used). This number
sequence is saved to the RFID tag, offering worldwide unique identification of the
tagged object.
The system of Electronic Product Codes (EPC) was defined by GS1/EPCglobal
for use in inventory management. Tags with memory banks for EPC codes must
be programmed by the user. The memory of new tags must not contain any valid
EPC codes. The EPC numbers are managed and assigned by GS1. To obtain
EPC numbers, please contact the GS1 branch in your country
The electronic product code is defined by EPCglobal with at present 13 different
encryptions. SGTIN-96 (serialized global trade item number) is given here as an
example of a frequently used encryption. SGTIN-96 has a defined format, and is
structured as follows:
1.
Header
: The header specifies the EPC standard used, and denotes the
number sequence.
2.
Filter value
: Denotes the unit of the product, for example, end product, ad-
ditional packaging, pallet.
3.
Partition
: Denotes the point at which the following company prefix ends
and the object data begins.
4.
Company Prefix
: Assigned sequence of numbers that identifies the pro-
ducer.
5.
Object class
: Sequence of numbers that describes the object, e.g., item
number.
The company prefix and the object class are each of variable length, but to-
gether are always 44 bits long.
6.
Serial number
: Sequence of numbers that identifies the item, for example,
the sequential serial number of the item.
