Indian Jeweler Seeks 100 Percent Security From RFID

When an item is sold, the store's personnel detach and deactivate its tag through the software. The tag can then be reused on another item.

Although the ceiling-mounted interrogators have a long read range, they have been designed so that they can not detect a tag's signal the moment a tagged item passes the exit, thereby triggering an alarm. This function provides an additional layer of security with redundancy to the exit door reader, which also sets off an alarm if an active tag passes through that door.

To enable the ceiling readers to do this, Agrawal notes, Orizin has designed special reader antennas and a patent-pending software algorithm. "We achieved this after rigorous testing," he says.

The benefits Jewelex India is seeking are 100 percent security—through tamper-proof and foolproof detection of tagged items passing through the exit—as well as real-time inventory that reduces mistakes and the amount of time the store's staff spends manually checking each item. The company would not comment for this article.

According to Agrawal, the system is commercially available worldwide and can transmit at 915 MHz in the United States.
