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

Abstract

The invention relates to a design and manufacturing method for an anti-counterfeit electronic label, an anti-counterfeit electronic label and anti-counterfeit packaging, belonging to application technology in the field of wireless radio frequency identification. The method comprises the following steps that a label antenna is designed to be a folded symmetry dipole antenna; fragile paper is used as a substrate of the antenna and is firmly combined with the antenna to form a whole; an island-shaped composite pad is arranged at the bottom of the fragile paper substrate and aligned with the center of a chip so as to enable an arc space structure of the antenna to form at the center where the chip is located; an adhesive is applied on the surface of the fragile paper substrate, a surface bar coated by a film forming agent is compounded on the top of the adhesive, and the dimension of the surface bar and the adhesive is greater than the area of the fragile paper substrate. The tearing-proof and sticking-proof anti-counterfeit electronic label prepared by the method enables reliable reading of the label on metal surface to be realized, probability of accidental damage of the label in the process of applying and transporting to be eliminated or reduced and anti-counterfeit performance to be improved. The design and manufacturing method provided in the invention is ingenious, simple and practicable, and enables low cost and great production capacity to be achieved.

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

[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.
