[0002] Anti-counterfeiting labels are labels that can be affixed to the surface of the labeled item, its packaging, or any related accessories, serving an anti-counterfeiting function. The anti-counterfeiting features and identification methods of anti-counterfeiting labels are the essence of the label, preventing activities aimed at deception and unauthorized imitation or duplication.

[0003] Chinese Patent Application No. 202420601312.7 discloses an anti-counterfeiting label with variable digital codes, belonging to the field of anti-counterfeiting label technology. It includes a face paper layer, a pattern printing layer at the top of the face paper layer, a variable QR code layer in the middle of the pattern printing layer, an anti-counterfeiting layer above the pattern printing layer and the variable QR code layer, an adhesive layer at the bottom of the face paper layer, and a backing paper layer at the bottom of the adhesive layer. The sides of the anti-counterfeiting layer, pattern printing layer, face paper layer, adhesive layer, and backing paper layer are flush. This invention programs the variable QR code layer and prints personalized patterns on the pattern printing layer, enabling the printed anti-counterfeiting labels to achieve personalized features, ensuring each label has a unique pattern. From color to pattern, everything can be different. The pattern and digital codes of the anti-counterfeiting layer are also different, making it a completely personalized product. The backing paper layer is peeled off, and the label is pasted on the adhesive layer for easy use.
