Barcodes are used to carry commodity information, and each commodity has a unique barcode.

In the anti-counterfeiting industry, bar codes are mainly used as anti-counterfeiting goods to carry anti-counterfeiting information, but some anti-counterfeiting companies directly make anti-counterfeiting codes into bar codes.

So bar codes are not anti-counterfeiting, but anti-counterfeiting has been used as anti-counterfeiting labels in this way.
