Two-dimensional code anti-counterfeiting and anti-smuggling refers to generating a series of numbers through technical means, and then converting them into two-dimensional codes. Users can obtain the authenticity information of products by scanning codes. Anti-smuggling means that if the same QR code is scanned multiple times, the management background can see the number of code scans, and normally it can only show that it has been scanned once. When it is found that the product has been scanned many times and appears in the city where it should not appear, it can be judged that it is smuggled between dealers.
