The QR code itself is not anti-counterfeiting. It is necessary to have a mobile APP application and an enterprise commodity information database to achieve anti-counterfeiting effects. The principle is to assign a unique two-dimensional code to each product, and use non-replicable material printing technology to ensure that the two-dimensional code can not be copied. Consumers can query the QR code by downloading the mobile phone APP when purchasing the goods, and check the goods. Information, manufacturing companies and other information can be identified.

The anti-counterfeiting of the two-dimensional code is generally composed of two layers. The use process needs to be raised to the bottom layer of the surface layer. The bottom layer of the two-dimensional code anti-counterfeit label is generally composed of special colloid, so it will not be revealed together when the first layer is uncovered. This prevents the tag from being transferred to the anti-counterfeiting function.

The characteristics of the QR code anti-counterfeit label:

1, two layers of labels, you can print more information content.

2. The label cannot be lifted to prevent the label from being used twice.

3. The two-dimensional code anti-counterfeit label can also combine the advantages of fiber texture, digital variable graphics, two-dimensional code and other technologies to form a comprehensive anti-counterfeiting mark with multiple anti-counterfeiting functions, and enhance the anti-counterfeiting strength of the anti-counterfeiting mark.

4, two-dimensional code anti-counterfeit label with a certain background data operation, can achieve points, anti-smuggling, intelligent marketing and other functions.

QR code anti-counterfeit label identification method:

Uncover the label surface and try to see if the bottom layer can be completely uncovered.

The application scenarios of QR code are very broad, and various applications have unique scenes and uses. The personalized features are obvious, and the scope is applicable to:

1, the main reading class application (mobile phone code)

(1) Traceability

The green food production source allocates barcodes to the food, and enters detailed information and certification status for each food with the quality certification agency. When consumers purchase food, they can use the mobile phone to scan the code or send a text message to query the product certification status and other information anytime and anywhere, and report false and incorrect information in time.

(2) Anti-counterfeiting

The two-dimensional code is printed on the bills, documents and high-value products, supplemented by the client and the background verification system, to form an information security application. In such an application, the client can identify the pre-generated ticket or product information in the verification system after identifying the two-dimensional code. By comparing these information with the real thing, you can verify the authenticity of the object.

(3) Advertising media

The merchant will print the QR code containing the website in magazines, newspapers, promotional materials, outdoor advertisements, and users can quickly access the merchant website by scanning the client scan through the QR code installed in their mobile phone, which strengthens the merchant and potential. User interaction enriches the information contained in the ad.

(4) Electronic business card

When printing a paper business card, the company prints the name, contact information, e-mail, address and other information in the form of a QR code on the business card. The user who receives the business card can use the mobile phone client to read the QR code on the business card, and then the information contained in the QR code can be stored in the address book of the mobile phone.

(5) Shopping through train

On a larger print ad, the hot product will be displayed in the style of the shelf, supplemented by the necessary text description. If the user finds that he or she has the goods he needs, he can use the mobile phone to take the code and directly enter the order page. After filling in a small amount of information (such as the number of pieces of shopping), the order can be completed, and the step of re-searching for the product by the user is omitted.
