Indian Jeweler Seeks 100 Percent Security From RFID
Hoping to eliminate all shrinkage, Jewelex India is testing a system that uses active tags to track high-value items in real time, while utilizing less expensive passive tags for lower-cost jewelry.
Dec 30, 2008—Jewelex India Pvt. Ltd., a jewelry retailer based in Mumbai, India, is completing a four-month pilot of a radio frequency identification system designed to improve inventory tracking and security for products in its stores. The system—which employs passive RFID tags for its less expensive inventory, and active tags for high-value items—is in place at its Opulence store in the Hotel Shangri-La, located in New Delhi.
Developed by Orizin Technologies, the system provides real-time inventory tracking with RFID interrogators installed in the store's ceiling, to take a constant inventory of items bearing active tags, as well as a countertop RFID interrogator to read the passive tags attached to lower-value items.
All jewelry is first tagged as it is placed in cabinets on the sales floor—some with less expensive reusable passive tags, and the high-value items with battery-powered tags. Both tag types employ a proprietary air-interface protocol operating at 865-868 MHz. The passive tags measure approximately 1 inch by a quarter inch, while the active tags are about 1 inch square and a quarter-inch thick. Tags are typically attached to the jewelry using a plastic loop. Each tag is encoded with a unique ID that store personnel can input into a back-end server and link to data regarding that item, according to Prashant Agrawal, Orizin's founder and CEO.
The active tags, with a battery life of about eight months, have a longer read range and do not require inventory to be conducted by employees using such traditional methods as sweeping a handheld reader along the store cabinets, or by installing RFID readers in the cabinets themselves.
