Anti-counterfeit packaging has a new law

Japan recently developed and launched a logo card and information identification system that can use electromagnetic waves to identify authenticity. Its biggest feature is that it is different from the “bar code” that uses light reflection. It is not necessary to directly touch the logo card to accurately interpret the information, and it can instantly identify the authenticity of the ID card and the monthly pass. It can also be used in many areas such as brand name merchandise signs, anti-fake packaging, and merchandise management.
This kind of information identification system is very simple in structure, it is the electromagnetic wave hits the sign card (this kind of record identification information card length is 3â–¡, the width is 4.8â–¡, the thickness is 0.07â–¡), receives the reflection to return the weak again Electromagnetic waves can be accurately identified. If there are non-metallic obstacles, such as cloth and paper, between the recognition machine and the card, it will not affect its recognition ability and interpretation accuracy.
The information card was produced on a polyethylene sheet by a special process and a circuit composed of aluminum wires was set. When a pulsed electromagnetic wave hits the top, the circuit resonates and reflects the card's unique frequency electromagnetic wave. Therefore, the thickness and shape of the wiring are critical. As the parameters of the circuit change, the frequency of the reflected electromagnetic wave changes and the information is different.
Generally speaking, 14 pieces of information can be recorded on the above-mentioned 3 × 4.8□ size card. If you increase the number of cards used in parallel, it is entirely possible to identify a large amount of information.
At present, a reflected wave recognition system that can accept 5-50M Hz electromagnetic waves has been made. When 10 planes of logo cards are arranged to receive electromagnetic waves, the accuracy of identifying 10 cards within 1 second from the machine at 5 inches can reach 100. %.
This kind of electromagnetic wave information identification system has good physical properties. Not only can it withstand a temperature change of -70-100°C, but it can be as soft as paper, and it can be bent freely without damage. At present, the cost of producing such a card is relatively low, about 10 yen. If an identifier is included, the price is about 10 times that of a conventional barcode system.
In addition, the information recognition system can also be used to identify the current barcode, magnetic card, etc., but it must be in direct contact with the recording medium during recognition. Therefore, this newly developed identification system can be widely used in high-end packaging products and merchandise management of shopping malls and factories, as well as financial cards and personal information identification. The prospects are very good.
