Jewelex India Pvt. Ltd., a jewelry retailer in Mumbai, India, implemented a four-month RFID pilot project in the Opulence store of the Shangri-La Hotel in New Delhi to improve store inventory tracking and product safety. This system uses passive RFID tags and active tags. Passive tags are used for low-priced goods and active tags are used for expensive jewelry.
This system was developed by Orizin Technologies. The RFID reader installed on the ceiling of the store continuously counts the items with active tags, while the RFID reader on the counter reads the passive tags of low-priced goods, thus realizing the inventory of the store. Real-time tracking.
Jewelex India currently only installs this system in one store to test RFID technology. If the pilot project succeeds in improving inventory tracking and safety, the company plans to use this solution in all three retail stores (two in India and one in Dubai).
All jewellery placed in the store cabinets are labeled. Low-priced items use cheap, reusable passive tags; high-priced items use battery-powered active tags. The operating frequency of the two types of tags is 865-868 MHz, using a proprietary air interface protocol. Passive tags are approximately 1 inch * 1 quarter of an inch, and active tags are approximately 1 square inch and 1 quarter of an inch thick. The label is attached to the jewelry with a plastic coil. Each tag has a unique ID number, which corresponds to the information of the item in the back-end database, said Orizin creator and CEO Prashant Agrawal.
Apply active RFID tags on high-priced jewelry
Active tags have a battery life of 8 months and a long reading distance, so employees do not need to use traditional methods for inventory: such as using a handheld reader to browse store cabinets or install RFID readers on the cabinets.
If someone attempts to damage the active tag, detach the tag from the jewelry, or take the labeled item away from the store, the Orizin system will trigger an audible alarm. The software will also detect the movement of the goods. For example, if a jewelry is taken out of the cabinet and placed in other areas of the store, the system will also send an alarm to notify the staff.
The reader is installed on the ceiling of the store where it cannot be seen by the public. The number of readers required by the store depends on the size of the store. “A reader can cover an average of 400 square feet,” Agrawal said. “If the reader is 10-15 feet above the ground, it can scan all the active tags in the store.”
In addition, for safety reasons, a reader is installed under the floor of the store exit. If a labeled jewelry leaves the store, the reader captures the tag ID code, triggers the system to send an alert in the form of an email or text message to the authorized store management personnel, and change the status of the item to “lost” in the software. In addition, the ceiling reader can be set to scan all active tags at a certain time interval. If the check label is not found during the scan, the system will issue an alarm and determine that the corresponding item has been lost.
For low-priced goods, passive RFID readers read passive tags by placing a plate of labeled jewelry on a desktop reader. The read data is uploaded via Ethernet and integrated into the store’s jewelry management system Ornate.
According to Agrawal, passive tags are more cost-effective than active tags. “Therefore, stores only put active tags on valuables, and passive tags are used for the rest of the items,” he said.
When a product is sold, store employees use software to disassemble and kill the label, which can then be used on other items.
Jewelex India hopes to achieve 100% security and real-time inventory. According to Agrawal, the Orizin system is sold worldwide and runs at 915 MHz in the United States.
