The first is a brief introduction to RFID. It will introduce the framework of RFID as an anti-counterfeiting system, including the structure of tags and data. There is also a hardware product used in the anti-counterfeiting system. There is no arrangement for the video demonstration due to time constraints. RFID has a very big advantage, that is, it is very small, and it can be read and written, and it is very adaptable to the environment. Compared with other anti-counterfeiting information, its biggest advantage is that it has a relatively large amount of information, which has a larger increase in storage capacity than ordinary barcodes or other information carriers.
At present, RFID has already begun to have some applications in anti-counterfeiting. Why is RFID more suitable for anti-counterfeiting? Anti-counterfeiting is very important because it is difficult to copy such a thing that you use for anti-counterfeiting. If RFID items are produced normally, the cost is very low. At present, an RFID tag can be worth a few cents, and the cost is now 7 or 8 cents, which is 5 cents. If it is not normal, if you want to copy an RFID chip, you can probably make an RFID chip from the design The cost to manufacture is 1 million U.S. dollars to calculate. From this point of view, the benefits of RFID are very clear.
It can be seen from RFID that the cost of illegal production of chips is very high, and the total number of companies that can produce RFID chips in the world should not exceed 20. If a counterfeit RFID chip is found, it is very easy to track, and it is very easy to find the source of the chip and the entire production. This is a very big benefit.
The second advantage, when using RFID chips for anti-counterfeiting, is the combination of chip manufacturers and application vendors. For the anti-counterfeiting information, it is not only the anti-counterfeiting manufacturer’s own control, in addition, a lot of encrypted information in it is written by the application unit into the label, so that it can form the real final anti-counterfeiting label. Let’s take a look at the company that produces anti-counterfeiting products. It cannot make a real product that meets the anti-counterfeiting requirements.
RFID has been used in anti-counterfeiting with very successful cases. The first successful case was the second-generation certificate. The number of second-generation certificates issued in China has reached 1 billion, and the benefits of the second-generation certificate are gradually being seen. If you are flying by plane, you can automatically sign in with the second-generation card. If you don’t have the second-generation card, it will be very troublesome to input. If you are staying in a hotel and show your second-generation card, you can immediately come out with an accommodation registration form and sign a letter.
If you look at the train tickets, you can see the train tickets with electronic tags. The Guangzhou-Shenzhen Railway uses electronic tags and is one-time use. Why does the Guangzhou-Shenzhen Railway use RFID? It is because they found that there are too many fake tickets, which can be as high as 2% to 5%. Why are there so many fake tickets for Guangzhou-Shenzhen Railway? Because it is generally not full, it is more difficult to check the ticket. They don’t necessarily use a fake ticket. For example, if this ticket is a ticket on June 13, then he will change 3 to 8. This is very easy, and it’s 18 to do it again, and it’s very difficult to detect this ticket. is fake. This is a big problem.
The third is medicines, anti-counterfeiting and injection molding of medicines, the State Food and Drug Administration is studying how to use RFID for tracking and anti-counterfeiting of items. At present, the overall plan has been undergoing some technical and feasibility certifications, and there has been a preliminary result.
RFID is used in the anti-counterfeiting process, which consists of many applications, including equipment, tags, software, middleware, and so on. This is the entire framework of the RFID system for anti-counterfeiting. You can see that the electronic tags start from the manufacturer to the distributor, and then to the retailer at the end of the electronic tag to read and write with the electronic tag, and finally obtain the product tracking information.
When RFID is used, a technology is used, we call it digital signature. Why can RFID be used as an important anti-counterfeiting function? It is because there can be a large amount of information, and digital signatures can be placed inside. The digital signature is the only information of the label + the only information of the product + the manufacturer’s own secret key. These three contents are indispensable. If it is only the label manufacturer, it is impossible to produce a complete information record, so that the information in the label completely carries the manufacturer’s information. Manufacturers can use their own secret key to put it in the label. So everyone sees that the final anti-counterfeiting label is not only completely determined by the manufacturer of the anti-counterfeiting label, it is actually only a semi-finished product provided by the anti-counterfeiting label manufacturer. Only when the manufacturer writes the manufacturer’s own information and product information into it, the label can truly represent the identity of the product. Therefore, digital signature technology is used to ensure the information security of the label.
Another example, this is the label used by Wuliangye. There should be 20-30 million wines in the market. When you open the wine you bought in a Wuliangye specialty store, you can see that the appearance of the label does not look much different from the original Wuliangye label. The four letters of RFID are added to the left side. If you see the four letters of RFID, it will be Know that there is an RFID chip inside. This label has several features added together. The mark of Wuliangye itself uses traditional anti-counterfeiting information, and the ink itself is anti-counterfeit, and has a special feature. There is also a special mark inside. Use an electronic tag, which includes a unique code, including the unique code of the chip, and then also includes the secret control information, which also includes product information. If you read this label, it will record the date on which the label was produced on which production line, the alcohol content, and even a lot of data on the production of this bottle of wine in the database. This tag antenna has a special technology. When it is attached to the wine bottle cap, it will be difficult to tear off. The antenna will be torn off when it is torn off. After tearing off, the chip will be separated. It is also extremely difficult and extremely costly to get the antenna up. Therefore, it can be seen that this tag is an effective combination of traditional anti-counterfeiting technology and RFID anti-counterfeiting tags.
There are also the coding differences of the items below, including the serial number of the product, the date of production, and some calibration codes for verification. There are some basic information about items, either in plain text or in secret text. There are many products needed to support the entire system, including some label products. Of course, a lot of software support is needed in the middle. The middle software support includes the control of the reader and the work of integrating a lot of software to the system.
I probably want to introduce some of these things to you. I would like to introduce to you that there are big problems in the whole project process, that is, many technical difficulties have been gradually overcome. I want to talk about a few questions, first of all, the production line. The production line of Wuliangye is very fast, and it takes about one second for a bottle of wine to pass through the packaging line of the production line. This label needs to be read and written in one second, and this bottle of wine is going forward on the assembly line next to the bottle. Therefore, it is necessary to ensure that each bottle of wine must be written, and this bottle of wine cannot be written twice. There is software control and hardware realization, which is very complicated. At that time, the most troublesome thing to solve was how to ensure that the wine was written in 100% when the wine was lined up on the production line and a bottle came. At that time, the error rate was less than two per thousand. It was such a requirement. At that time, we spent a lot of effort to complete this kind of work.
How can we read the label of the product in the user area? At the beginning, we thought of various methods. Of course, the best way is that everyone has a mobile phone. Can you use a mobile phone to read it? Finally, the technology is realized. The difficulty and business difficulty are very high. Finally, we made a method. First, implement it in a distributed manner and first in a specialty store.
A reader is used in the specialty store, and all customers in the specialty store can go to the specialty store to read after buying the wine, so as to verify the authenticity of the wine. In this way, things can be pushed away smoothly. In the end, from the point of view of this matter, I feel that there are two important points in this matter.
One, we must pay attention to the consideration of the entire system. The most difficult part of the whole system consideration is the production process. How to write the electronic label information without affecting the original production process.
Second, start with simple things, don’t make things too complicated all at once, as this will make our implementation process very difficult. Start with simple things, complete simple things, and gradually expand. At the end of this year, Wuliangye will launch a mobile phone that can be read, as well as a gift-like reader. This reader can be used to verify the authenticity of customers who purchase a lot.
