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.
