Generally, QR codes cannot be used as anti-counterfeiting basis. In one case, if the two-dimensional code information of each package of the same commodity is different (there is an encryption number, and the manufacturing cost is high), that is, the commodity number is unique (these numbers are stored in the database by the merchant, and there is a query record).
If the purchased product has an anti-counterfeiting code, you can inquire according to the phone number and website prompted by the product. If it can be found and displayed as the first query, it is genuine. There are generally four ways to inquire about security codes: telephone inquiry, short message inquiry, website inquiry and manual service desk. Generally, it is the most intuitive and quick to inquire about products in official website, which is recommended. If you can't find the security code information, it means that the product is probably a counterfeit product, or it may be a system problem (you need to find the manual service desk to confirm).
Why can't the QR code of multicolored jellyfish be scanned? It is true that all the security codes have been found, but one QR code can't be scanned. Where did you buy it? It is best to choose a regular five-star store to buy. Please consult me if you have any questions about colorful jellyfish.
Why can't the QR code app scan the security code? You can scan it with wechat. If not, there is something wrong with the code itself. Find the company that gave you the safety label. Some codes are poorly printed and have low recognition.
Both the QR code and the security code are real, but the smoke is fake. If the cigarette is confirmed to be fake, scanning the QR code for anti-counterfeiting also shows that it is true. There is only one possibility, that is, someone changed the real cigarettes and installed fake cigarettes.
Because the anti-counterfeiting QR code is one object and one yard, the QR code on each package is different, so you can't scan it again. Now that you have scanned and tested it, it proves that there is no problem with the anti-counterfeiting QR code. The problem lies in the product itself.
But it is impossible for someone to replace all the boxes of real cigarettes with fake cigarettes and then seal them. Too much trouble. . . .
I'm not sure about other people's anti-counterfeiting QR codes, but 9 1 anti-counterfeiting technology can really achieve one object and one code, and it can only be scanned once.
Are all products with security codes real? Your worry is not unnecessary.
I am a salesperson of an anti-counterfeiting company.
Now cost molecules will cheat in the following ways.
1. The overall design of the anti-counterfeiting label is similar, but the anti-counterfeiting inquiry method has been replaced, and all of them have been changed to the inquiry method of the anti-counterfeiting company with cost. After dialing, it will show that it is genuine. But it's actually fake.
2. The overall design of the anti-counterfeiting label is exactly the same, and the anti-counterfeiting inquiry method is the same. But the anti-counterfeiting code is a copied genuine anti-counterfeiting code or a completely fabricated anti-counterfeiting code. For the former, the consumer prompts "this product has been inquired for many times" when inquiring, while for the latter, the anti-counterfeiting telephone voice prompts "the anti-counterfeiting code does not exist".
3. If the anti-counterfeiting company that makes genuine labels is poorly managed and mercenary, the cost molecules may buy real anti-counterfeiting labels in the anti-counterfeiting company.
So be sure to go to a regular supermarket to buy products.
The above questions were answered by Zhang Delong of Beijing Kaixun Shang Hui Anti-counterfeiting Technology Co., Ltd.
The QR code of Philips purifier can't be scanned. Is the product real? Did you buy it in a specialty store? You must first make sure that you bought it in a regular shopping mall. General brands will not have such problems, such as Epsel, Philips and Bruyal, which should be very formal and will not be swept away. You'd better check it again.
The QR code cannot scan the product price. Is this product real? The information in the QR code is filled in by the manufacturer according to his own needs, and not every QR code has price information.
Is the medicine that can't be scanned by QR code true or false? This is not necessarily true, because the databases of general code scanning software are not official now, so it is normal that some of them cannot be scanned.
Whether this string of numbers under the QR code is an anti-counterfeiting code or a product number is often the content of the QR code and belongs to the anti-counterfeiting code (or traceability code).
Is the product without QR code and barcode real? Generally speaking, it is an irregular product, and the probability of counterfeit goods is relatively high.
It is not illegal for goods to have no bar code, but it is necessary to have a bar code to enter a slightly larger supermarket or shopping mall. Weighed products and products not sold in supermarkets or shopping malls can have no bar code.
