Design and manufacturing method for anti-counterfeit electronic label, anti-counterfeit electronic label and anti-counterfeit packaging

Abstract

The invention relates to a method of designing & manufacturing anti-counterfeiting RFID tags, the anti-counterfeiting RFID tags obtained and the anti-counterfeiting package related. The invention belongs to application of radio frequency identification technology. The tag design comprises an adopted folded dipole antenna form using fragile paper as antenna substrate board. Integrate antenna and fragile paper substrate board securely and firmly. In alignment with the central position of the chip overlay an “island”-type compound gasket on the bottom surface of fragile paper substrate, so that the antenna forms an arch spatial structure at the center position of the IC chip. Coating the fragile paper substrate surface with adhesive, then compounding with cover layer material which coated with release fragile film former. The sizes of surface material and adhesive are larger than that of the fragile paper substrate board. The tamper-evident anti-counterfeiting UHF RFID label achieved through this method can be read reliably on the metal surface. It can avoid or reduce the probability of accidental damage during label sticking and transportation and improve anti-counterfeiting performance effectively. This invention of designing and manufacturing method is ingenious, simple, inexpensive and of high capacity.

Description

technical field [0001] The present invention relates to the application technology in the field of radio frequency identification, in particular to a method for designing and manufacturing an anti-tampering ultra-high frequency electronic label that resists metal surface interference, an anti-counterfeiting electronic label obtained by the method, and an anti-counterfeiting package with the electronic label built in . Background technique [0002] Radio Frequency Identification (RFID) technology has been widely used in many fields such as logistics industry and retail industry, which effectively improves management efficiency and greatly saves labor costs. The radio frequency identification system is composed of RFID electronic tags and RFID readers. The working process is that the RFID reader generates electromagnetic waves of a specific frequency and sends them out through spatial coupling (also known as sending question signals). When the RFID electronic tag enters When ...

Problems solved by technology

However, since the outer packaging of the product is covered by aluminum foil, the label cannot be effectively read without opening the packaging, and opening the outer packaging destroys the integrity of the product and reduces the anti-counterfeiting effect of the RFID electronic tag

[0005] Since UHF electronic tags use radio waves in the range of 900MHz to communicate with readers, they can achieve a longer reading distance, but they are greatly affected by metal and liquid environments, and they may even fail to communicate when attached to the surface of metal materials.

At present, aluminum foil or vacuum aluminized materials are commonly used for packaging and printing in the food, beverage, pharmaceutical, cigarette, and electrical industries, so it is impossible to apply electronic tags to achieve effective management of anti-counterfeiting and anti-channeling of single products

In addition, most of the anti-counterfeiting labels currently attached to the outside are made of fragile materials, which have the effect of tearing and destroying them. However, if they are directly applied to anti-counterfeiting electronic labels, the electronic labels are easily damaged during the attachment and transportation process.
