Anti-theft label for metal containers

Practical, safe and easy to recycle metal containers have many advantages, but are generally incompatible with radio frequency (RF) anti-theft tags because they absorb the waves emitted by the antenna, which jeopardizes the operation of the process. . To avoid theft, large retailers are obliged to place risky products in locked cabinets, which not only restricts staff, but can also deter consumers from buying goods. Checkpoint Systems, which specializes in developing anti-shrinkage and automatic identification labels, has finally found a solution. Its label, called Metal Label, can be detected by a gate, even if the packaging is made of metal. This, according to the company, is the first time on the market.

Recalibration of frequency

“The principle is to recalibrate the label frequency of about 8.2 MHz so that it can be detected by the antenna”, explains Julien Tibult, RFID Manager at Checkpoint Systems, not to mention this patented technology that took years of development. In order for the label to work, the chain it contains must be slightly offset from the surface of the container. The result is a 2 to 3 mm thick device compared to a few microns for a conventional label. This micro-revolution in the world of RF-tags responds to the important evolution of shrinkage in stores. Many items in metal packaging have long been a concern, including those with high face value, such as baby formulas, some coffees, foie gras, canned tuna or crab, and canned energy drinks, which can sometimes surprise or even surprise prices. deodorants and face creams. And then there was Covid, who stimulated DIY. Specialized brands have experienced a resurgence of theft of items presented in metal pots, such as paints or varnishes, or those that, although presented in blister packs, are made of metal, such as wood.

Flights have halved

“We are finally responding to companies that have not had the opportunity to defend themselves,” Says Julien Tibult. Tests conducted so far in Europe and the United States have proved convincing. Most retailers who managed to unfold metal labels noticed a 50% reduction in shrinkage when one of them noticed that the theft in one of the product lines had decreased by 85% in six weeks. Labels are available in 41 x 14 mm format, so they can also be placed on thin products such as cosmetics. They consist of an adhesive liner, which is glued to the product, and a plastic housing, inside which is an electronic circuit. Like other radio frequency tags, this circuit is disabled when ordering. The cost of Metal Label is 110 euros per thousand copies. There is no need to modify the gate in the store.
