IUH-F192-V1-*
Product Description
• 4 bytes: Tag part number
• 1 byte: Marking
• 12 bits: Tag Mask Designer Identifier (MDID)
• 12 bits: Tag model number (TMN), defined by the manufacturer
• 4 or 8 bytes: Tag serial number
Depending on the manufacturer, the serial numbers do not have to be unique or may even
be omitted.
Bank 11: User memory
Bank 11 contains a memory that the user can freely access. The size of this memory depends
on the chip type, or this memory may not be present.
3.2.4 Elektronic Product Code EPC
The electronic product code EPC 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 used. This number sequence is saved to the RFID tag, offering world-
wide unique identification of the tagged object.
The EPC was defined by GS1 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 num-
bers, please contact the GS1 branch in your country (http://www.gs1.com/contact).
The EPC is defined by GS1 with at present 13 different encoding schemes. SGTIN-96 (serial-
ized global trade item number) is given here as an example of a frequently used encoding
scheme. SGTIN-96 has a defined format, and is structured as follows:
1. Header: The header specifies the EPC standard used, and denotes the number se-
quence.
2. Filter value: Denotes the unit of the product, for example, end product, additional pack-
aging, 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 producer.
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 together are al-
ways 44 bits long.
6. Serial number: Sequence of numbers that identifies the item, e.g., the sequential serial
number of the item.
3.2.5 Influence of various materials on the sensing range
In the UHF range, the nature of the surrounding area and the surface to which the transponder
is secured have a serious influence on the range that the system can attain. The UHF transpon-
der cannot be mounted on metal without requiring adaptations. Glass has a negative influence
on the sensing range when used as a mounting surface. If a UHF transponder is mounted on
damp material, the sensing range is much poorer than the range of a transponder mounted on
dry material. The mounting surface often affects the read range much more than the material
between the transponder and the read/write device. The graph shows the effect of different
materials on the sensing range.
