Japan developed a product anti-theft plastic label

A Japanese company has developed a product anti-theft plastic tag that can be combined with an electronic monitor to form a supermarket anti-theft security system.

This commodity anti-theft plastic tag is an electronic alarm. If someone attempts to forcefully remove from the goods, a 75 dB self-oscillating alarm sounds. This alarm sound can be detected by an acoustic detector (ATD) placed in the supermarket and amplified by a power amplifier so that people in the store can hear it. If an uninvited guest wants to bring a product with this anti-theft plastic label out of the supermarket, when it goes to the exit of the protected area, another alarm will be triggered. When the microprocessor detects this coded alarm message, it immediately forwards it, thus making the main Alarms and alarms in supermarkets made a harsh alarm. If the customer is a normal shopper, the anti-theft plastic tag will not report to the checkout counter. At this time, the clearing staff can use a special tool to remove it, and send pleasant harmonic and flash signals. If the clearing agent forgets to remove it, it will issue four “beep” sounds to remind the clearing staff not to forget.

The anti-theft plastic tag is powered by a miniature battery and uses a vibratory switch that can detect any action to turn on the circuit. If the product is not touched, the vibratory switch is always off and will not turn on.
