You can copy some simple QR codes and barcodes. If the counterfeit goods copy the real product QR code or barcode, the information scanned by the mobile phone is still the real product information. If you can't find the product information after scanning, you can't judge it as a fake. Consumers can't use the scanning results as the basis for distinguishing the authenticity of goods.
Extended data:
Features of QR code:
1, high-density coding, large information capacity: it can accommodate up to 1850 capital letters or 27 10 numbers or10/08 bytes, or more than 500 Chinese characters, which is several times higher than ordinary bar codes.
2. Wide coding range: Barcodes can encode digitized information, such as pictures, sounds, characters, signatures, fingerprints, etc. , and represented by bar code; Can represent multiple languages; Can represent image data.
3. Powerful fault-tolerant and error-correcting function: This enables the QR code to be read correctly when it is partially damaged due to perforation, fouling and other reasons, and the information can still be recovered when the damaged area reaches 30%.
4. High decoding reliability: far lower than the decoding error rate of two millionths of ordinary bar codes, and the error rate does not exceed one millionth.
5. Encryption measures can be introduced: good confidentiality and strong anti-counterfeiting.
6, low cost, easy to manufacture and durable.
7. The shape, size and proportion of bar code symbols are variable.
8. Two-dimensional barcode can be read by laser or CCD reader.
