Teacher Tian talks about anti-counterfeiting | How does QR code achieve product anti-counterfeiting? How much do you know about the doorway here?

Anti-counterfeiting is a multidisciplinary and strong cross-application field. There are many types of anti-counterfeiting technologies, such as design anti-counterfeiting, printing anti-counterfeiting, material anti-counterfeiting, physical anti-counterfeiting, digitalization, informationization anti-counterfeiting, structural anti-counterfeiting, biometric anti-counterfeiting, etc. At present, label identification products with anti-counterfeiting functions are widely used in commodity packaging and circulation processes, especially in currency, securities, certificates, medicine, food, tobacco, alcohol, cosmetics, clothing, electronics and other fields.

With the continuous changes in market demand, anti-counterfeiting technology is also constantly updated, iterated and combined, and more and more new technologies are used in commodity anti-counterfeiting. Especially with the acceleration of the informatization process, digital and intelligent technologies are constantly updated and iterated, and applied to anti-counterfeiting identification, which plays a very important role in commodity anti-counterfeiting and traceability management.

At present, the digital and intelligent anti-counterfeiting technologies we commonly use mainly include telephone code technology, QR code technology, image comparison technology, RFID technology, etc. In fact, these technologies themselves do not have anti-counterfeiting functions, and are mainly used for traceability and identification. However, these technologies combined with platforms and other technologies can help consumers judge the authenticity, so they are used in anti-counterfeiting label identification. In this article, the author first elaborates on telephone code technology and QR code technology in detail, hoping to give some application inspiration to label printing companies.

Telephone code technology

Telephone code technology appeared earlier and can be said to be the first generation of digital technology. It is a digital technology that uses coding technology, digital encryption technology, communication technology, computer technology, and printing technology to form an automatic identification anti-counterfeiting verification system. It can set a unique password for each label that enters the network, and store this password in the central database, and establish a telephone query system at the same time. When consumers buy products with telephone code anti-counterfeiting labels, they can make a phone call or send a text message and enter the password on the product to judge the authenticity of the product.

Around 2005, many code platform companies appeared in China, which effectively promoted the promotion, popularization and development of this technology. In addition, the national level has also launched electronic code anti-counterfeiting platforms in the fields of electronic product network access license, electronic drug supervision, quality and technical supervision, etc. For example, the electronic drug supervision code plays an important role in the status supervision of drug production and circulation, the realization of product traceability and management of regulatory departments and production enterprises, and the protection of the legitimate rights and interests of drug manufacturers and consumers.

QR code technology

The predecessor of QR code is barcode, which was first used in the information management of logistics and manufacturing. QR code itself has no anti-counterfeiting function, but is a symbol for recording information, which is used to record link addresses. However, with the rapid development of mobile communication technology, QR code technology has gradually begun to be applied in other fields, such as product packaging. By scanning QR code, consumers can obtain information about product ingredients, production batches and authenticity verification.

QR code anti-counterfeiting mainly uses QR code encryption technology to assign a unique QR code to each product. When consumers purchase goods, they can query the QR code through the mobile phone APP and verify the authenticity of the goods, manufacturers and other information. QR code can store rich product information, and it is not easy to be copied and misused through encryption technology, thus achieving high efficiency of product information anti-counterfeiting.

Diversified QR code anti-counterfeiting

With the development of digital printing technology, holographic technology and engraving technology, the forms of QR codes in labels are becoming more and more diverse, such as color QR codes, holographic QR codes, three-dimensional QR codes (also known as structural three-dimensional codes), etc., which are constantly emerging in anti-counterfeiting labels.

1. Color QR code anti-counterfeiting labels
Color QR code anti-counterfeiting labels usually combine multiple anti-counterfeiting technologies, such as anti-counterfeiting code digital information, anti-counterfeiting code color information and material feature information, to achieve triple or even multiple anti-counterfeiting effects. This multiple anti-counterfeiting feature makes the anti-counterfeiting label more difficult to be forged or copied, thereby improving the anti-counterfeiting of the product.

2. Holographic QR code anti-counterfeiting label
Holographic QR code anti-counterfeiting label is an anti-counterfeiting technology that combines laser holographic technology with information technology. Holographic QR code anti-counterfeiting labels are printed with QR code patterns containing relevant information, which can enable products to achieve "one object, one code". By scanning the QR code, consumers can not only check the authenticity of the product, but also increase the beauty of the label, thereby enhancing the product image. This type of label is often used in food and beverages (high-end bottled water, bottled beverages, organic fruits and vegetables, meat products, etc.) as well as high-end tobacco and alcohol product packaging, medicines, daily chemical products and other fields.

3. Structural 3D code anti-counterfeiting label
There is also a QR code on the market that is engraved by multi-layer materials. Because of its hierarchical structure, it is also called a structural 3D code. The structural 3D code is a material with an anti-counterfeiting structure containing multiple color layers. The anti-counterfeiting elements and information are randomly engraved on different color layers, so that different parts present different depths and different colors of structural characteristics. The structural combination pattern formed is unique and cannot be copied, and it has the characteristics of being difficult to copy.
