Analysis of anti-counterfeiting process of three-dimensional QR code anti-counterfeiting label

To improveQR code anti-counterfeiting labelFor the anti-counterfeiting performance, someone adopted a special design and developed a three-dimensional display of anti-counterfeiting labels. This kind of label uses a special process when printing, so when the temperature reaches 70 ℃, the two-dimensional code will change, so as to achieve the corresponding anti-counterfeiting effect. Today, we will understand its anti-counterfeiting principle through the anti-counterfeiting process of the three-dimensional QR code anti-counterfeiting label.

The appearance of the three-dimensional QR code anti-counterfeiting label looks the same as an ordinary anti-counterfeiting label. People need to scan the two-dimensional code with a mobile phone and then enter the corresponding anti-counterfeiting identification code for identification. And this anti-counterfeiting identification code will print the second layer of the QR code, which can only be revealed after the QR code disappears. People can use a lighter or other heating methods to heat the QR code security label. As long as the temperature is higher than 70°C, the upper black QR code will disappear and the security identification code will appear. And as the temperature continues to rise, the anti-counterfeiting identification code will gradually rise, and the pattern will be clearly visible. When the temperature of the two-dimensional code anti-counterfeiting label returns to normal, the black two-dimensional code will reappear, but the anti-counterfeiting identification code will not disappear. This can ensure the one-time use of anti-counterfeiting labels and prevent counterfeiting by counterfeiters.

Some people worry that the QR code on the anti-counterfeiting label of the QR code cannot be scanned after the high temperature, and the verification function will be lost. In fact, the appearance of the anti-counterfeiting identification code will not affect the scanning of the QR code. Therefore, consumers can directly scan and verify the anti-counterfeiting label after high-temperature processing. In order to allow consumers to test the three-dimensional QR code anti-counterfeiting labels more smoothly, the manufacturer will mark the verification method next to the QR code when printing the label.
