RFID in metal packaging

The co. and QinetiQ have launched a joint program to adapt QinetiQ's Omni-ID Pak(TM) integrated RFID technology for use in metal packaging. This will allow brand owners to integrate ultra-high frequency (UHF) RFID tags into metal packaging for a wide variety of applications at the unit level. Designed to mitigate issues such as signal reflection, detuning and grounding that can reduce or negate RFID's effectiveness on metal packaging or with aqueous-based products, the standalone Omni-ID Tag(TM) and integrated Omni-ID Pak(TM) technologies are said to leverage several of metal's inherent properties and shifts the format into an advantageous position. UHF tags may be mounted directly onto a metal substrate. The unique tag structure measures less than 1 mm thick and collects and focuses RF energy for efficient coupling to a chip. Using a beverage or food can as an example, the can itself would serve as the antenna, simplifying production of the RFID tag and further reducing costs. Existing Gen 1 and Gen 2 RFID tags complete the equation. The RFID chips need a short coupling antenna, and the co. says space is freed up on-pack for graphics and key messaging due to the small tag footprint.
