The QR code itself does not have anti-counterfeiting technology, but the real anti-counterfeiting function is the anti-counterfeiting system. The function of QR code is a carrier. The purpose is to access the anti-counterfeiting system conveniently and quickly by scanning the QR code, and get the feedback of the authenticity of the product.

Moreover, in order to ensure the uniqueness of the two-dimensional code label, the general anti-counterfeiting system will generally add the number of verifications on the label, usually 1, and the system will generally default that the first query is true. If it is not the first inquiry, it will not be recognized by the anti-counterfeiting system and belongs to counterfeiting. Therefore, the QR code anti-counterfeiting label is still very safe. Even if the counterfeiter wants to make a fake, he should carefully consider the cost of making a fake. Combining two-dimensional code with anti-counterfeiting technology, two-dimensional code label can realize two-dimensional code anti-counterfeiting.

Therefore, the most important thing on the anti-counterfeiting label is the anti-counterfeiting data, which is used to smuggle goods.
