With the promotion and popularization of printing technology, common anti-counterfeiting technologies on the market gradually present own disadvantages.

But this connection is very fragile. The counterfeits can be easily realized by only an attacker by adopting the means of recovering the package, promoting the printing technology, copying the inquiry code and the like.

In order to improve the counterfeiting difficulty, some enterprises adopt a mode of adding RFID labels, and due to the reasons that the manufacturing cost of RFID in the past is high, special equipment is needed and the like, counterfeiters give up counterfeiting low-value commodities from the economic benefit perspective. However, as the semiconductor technology is gradually mastered and popularized, the anti-counterfeit technology for the RFID is also seriously threatened, and particularly, the RFID which transmits a fixed ID only in one direction is very easy to be counterfeited. In addition, the RFID technology requires special equipment to read data, which cannot be read by a common mobile phone, so that ordinary people cannot process the data in time when needing to verify counterfeit products.

Recently, the anti-counterfeiting of the NFC chip is similar to the anti-counterfeiting method, so that some users cannot verify the anti-counterfeiting of the NFC chip without being supported by the equipment in time. This also leaves some counterfeiters with luck psychology to be available. The mode of printing the fixed ciphertext outside the common commodity is almost impossible to imitate in batch from the practical point of view. If the product is not deeply combined with anti-counterfeiting technology, a counterfeiter still has a plurality of opportunities to imitate the product.
