Product Description

General

The Tag-it HF-I Standard Transponder IC is part of TI’s 13.56 MHz product family which is based on the

ISO/IEC 15693 standard for contactless integrated circuit cards (vicinity cards) and ISO/IEC 18000-3

standard for item management. The Tag-it HF-I Standard Transponder IC builds the basis for various

available inlay shapes which are used as consumable smart labels in markets requiring quick and

accurate identification of items, such as:

• Asset tagging

• Electronic ticketing

• Anti-counterfeit prevention

• Distribution logistics and supply chain management

• Building access badges

• Express parcel delivery

• Airline boarding pass and baggage handling

User data is written to and read from memory blocks using a non-volatile EEPROM silicon technology.

Each block is separately programmable by the user and can be locked to protect data from modification.

Once the data has been ‘locked’ then it cannot be changed.

To give some examples, information about delivery checkpoints and timing, place of origin/destination,

pallet assignments, inventory numbers and even transportation routes can be coded into the transponder.

Multiple transponders, which appear in the Readers RF field, can be identified, read from and written to by

using the Unique Identifier (UID), which is programmed and locked at the factory.

For operation a reader with antenna is required to send a command to the transponder and to receive its

response (see Figure 1-1). The command of the Reader can be either in addressed or non-addressed

mode. The Transponder does not transmit data until the reader sends a request (Reader talks first

principle).

The Tag-it HF-I Standard Transponder IC is compliant to the ISO/IEC 15693 and ISO/IEC 18000-3

standard. To build a complete transponder, the Tag-it HF-I Standard Transponder IC has to build a

resonance circuit with the antenna it is assembled on e.g. an etched aluminum antenna.
