Where is the 18 digit security code on the cigarette?

18-bit code is usually attached to the bottom or side of the cigarette case. Scrape off the anti-counterfeiting coating on the upper layer to see the numbers inside.

The spray code is arranged up and down, and each line has three groups of numbers. At the time of identification, the number can be sent to the designated number by SMS. If you receive the message reply "The product you are looking for is produced by XXX company, and the code spraying is the first inquiry", it means that you are buying genuine products. If the prompt spray code has been queried many times, you need to pay more attention.

This method may not be completely effective. Many unscrupulous merchants will cut one side of the real cigarette case with a blade and replace it with fake cigarettes for packaging adjustment. This situation requires consumers to take more precautions and try to buy in regular stores.

Anti-counterfeiting products on the market can be roughly divided into five generations from the perspective of technical characteristics and functional evolution:

First generation products: products represented by laser labels.

Consumers also have no ability to identify the authenticity of labels, and labels are easy to forge. Without comparability, it is difficult to identify 60% counterfeit products and 100% genuine products; Secondly, the temperature change label is easy for consumers to identify, but it is also easy to forge. At the same time, nuclear track anti-counterfeiting and so on have also evolved.

Second generation products: query digital anti-counterfeiting labels.

Consumers can check the authenticity of digital labels by telephone, SMS, Internet, etc., but anti-counterfeiting numbers are only printed on the surface of paper and are easily forged.

The third generation product: texture anti-counterfeiting label.

Texture anti-counterfeiting is a kind of anti-counterfeiting technology which takes the speckle marks inherent in packaging materials as anti-counterfeiting identification marks. Consumers can check files through the internet, fax, telephone and other means to distinguish authenticity. Randomness increases the difficulty of forgery in principle.

The fourth generation products: security thread anti-counterfeiting paper technology and its application products, including all kinds of product anti-counterfeiting instructions and certificates, anti-counterfeiting bottle stickers, anti-counterfeiting labels and so on. Consumers can easily identify the authenticity by identifying whether there is a security thread embedded in the middle of the paper. The imitation threshold of this kind of anti-counterfeiting technology product is extremely high, and it is impossible to forge it by printing, which truly makes it "easy to identify and difficult to forge". Therefore, it is the most effective anti-counterfeiting technology product at present and for a long time to come.

The fifth generation product: wireless anti-counterfeiting technology-mobile Internet anti-counterfeiting technology. By affixing anti-counterfeiting labels automatically marked by mobile phones on products and packages, consumers can automatically scan them with mobile phones to identify the authenticity. Combined with texture anti-counterfeiting and security thread anti-counterfeiting, consumers will really feel at ease and comfortable shopping.

Paper grain anti-counterfeiting technology: Paper grain anti-counterfeiting technology is to carry out anti-counterfeiting by extracting and identifying the anti-counterfeiting features naturally generated by paper (that is, paper grain).
