RFID Technology in the Jewelry Industry: Overcoming Challenges with Smart Jewelry Trays (IoT Expo China-IOTE® Expo)


In the retail landscape, high-value products like electronics, luxury items, and appliances have shown a demand for RFID. However, the penetration of RFID in this sector has been limited. Through discussions with industry experts, we identify key reasons behind the delayed adoption of RFID in the jewelry industry:

Cost Constraints: The upfront investment required for RFID systems poses challenges, given the comparatively smaller and slower circulation of luxury items like jewelry.

Technical Complexity: The diverse shapes, sizes, and metal elements in jewelry demand RFID tags and readers adaptable to complex environments, posing difficulties for large-scale tag production.

Lack of Awareness: The jewelry industry has relatively less familiarity with RFID technology. While RFID finds widespread use in other sectors, its application in jewelry is still in its early stages, with technologies like barcodes being more mature.

However, a recent development involves a foreign company deploying a new RFID-based smart jewelry tray in a global jewelry retailer, aiming to address these challenges. Let’s delve into the workings of this RFID smart jewelry tray.


Working Principle of the Smart Jewelry Tray:

Based on RFID technology, each jewelry or watch is equipped with an RFID tag storing a unique ID. When placed on the tray, the built-in reader activates the tag with radio frequency signals, reads the information, and transmits it via a built-in antenna to a Bluetooth gateway device. The data is then uploaded to a server, enabling precise tracking and management of jewelry.

Avoiding Misreads:

To ensure high-performance and accurate reading, shielding materials, such as arsenic, are strategically placed around the tray’s periphery. This helps disperse radio frequency signals, preventing unintentional reading of neighboring tags. Carefully designed, these shielding materials effectively prevent misreads without compromising normal reading operations. Additionally, the smart jewelry tray adjusts the transmission power of the reader to narrow the ultra-high frequency transmission range.

Features and Advantages of the Smart Jewelry Tray:

Precise Tracking: The tray captures real-time RFID tag information, ensuring accurate tracking and positioning of each piece of jewelry.

Enhanced Efficiency: Through automated data collection and transmission, the smart jewelry tray significantly reduces manual input and verification, boosting operational efficiency.

Improved Security: Real-time monitoring of jewelry inventory helps prevent theft or loss. Data analysis and alerts also enable timely identification of potential security risks.

Optimized Management: Analyzing sales data assists businesses in understanding market demands and consumer preferences, providing robust support for inventory management and sales strategy formulation.

The application of RFID technology in the jewelry industry faces challenges such as cost, technical complexity, and limited industry awareness. However, with ongoing technological advancements, the future holds promise for the widespread adoption of RFID in the jewelry sector.
