RFID anti-counterfeiting technology embeds microchips into products and uses intelligent electronic tags to identify various items. These tags are produced according to the principle of RFID radio frequency identification, RFID tags and RFID readers exchange information through radio frequency signals, and compared with traditional bar code technology, RFID can save more time and manpower and material resources, reduce production costs, and improve work efficiency. It is being considered more and more as a replacement of barcode technology.
In response to the counterfeiting problem in the commercial field, a new and safe anti-counterfeiting technology is developed and designed by using the RFID radio frequency identification technology which is expandable, flexible and secure, combining the one-time one secret authentication mechanism and studying the initialization of the read-write and the electronic label and the verification of the electronic label.

For a long time, counterfeit and shoddy goods not only seriously affect the economic development of the country, but also endanger the vital interests of enterprises and consumers. In order to protect the interests of enterprises and consumers and ensure the healthy development of socialist market economy, the state and enterprises spend a lot of human and financial resources on anti-counterfeiting and anti-counterfeiting every year. However, most of the anti-counterfeiting technologies used in the domestic market are still made on paper-based materials, such as laser anti-counterfeiting, fluorescent anti-counterfeiting, magnetic anti-counterfeiting, temperature change anti-counterfeiting and special plate printing, etc. These technologies have played the role of anti-counterfeiting to a certain extent for a period of time, but so far the above anti-counterfeiting technologies are not perfect, and their technologies are not unique and exclusive and easy to Reproduction, thus can not play a real anti-counterfeiting role. Radio Frequency Identification (RFID) anti-counterfeiting technology, compared with other anti-counterfeiting technologies such as laser anti-counterfeiting and digital anti-counterfeiting, has the following advantages: each tag has a global unique ID number – UID, which is placed in ROM when the chip is made and cannot be modified or imitated; no mechanical wear and tear, anti-fouling; The reader has the performance of ensuring its own security, etc.
Great application value
Not only that, a large number of research results also show that: RFID anti-counterfeiting technology applies pseudo-random key and simple bit operation to realize the information exchange between read-write and electronic label, the algorithm complexity is low. In addition, this technology can effectively protect the authenticity of products, and can be better applied to the anti-counterfeiting protection of gold, jewelry, special books and other valuable items in circulation, which has a large commercial promotion value and application value.
RFID anti-counterfeiting components
- Tag: Composed of coupling components and chips, each tag has a unique electronic code and is attached to the object to identify the target object.
- Reader: Read (sometimes can also write) tag information equipment, can be designed for handheld or fixed.
- Antenna: in the tag and the reader between the transmission of radio frequency signal.
The basic working principle of RFID anti-counterfeiting technology is not complicated: the tag enters the magnetic field, receives the radio frequency signal from the reader, and sends out the product information stored in the chip by virtue of the energy obtained from the induction current (Passive Tag, passive tag or passive tag), or the tag actively sends a signal of a certain frequency (Active Tag, active tag or active tag), and the reader reads the information and decodes it, then sends it to the reader. The reader reads the information and decodes it, then sends it to the central information system for relevant data processing.
A complete RFID system is composed of a reader / writer and an electronic tag, that is, the so-called transponder and application software system. Its working principle is that the reader / writer transmits radio wave energy of a specific frequency to the transponder to drive the circuit of the transponder to send out the internal data. At this time, the reader / writer will receive and interpret the data in sequence, send it to the application for corresponding processing.
Specific applications of RFID anti-counterfeiting technology
1. Commodity anti-counterfeiting
It is the anti-counterfeit marker of commodity network scanning electronic label and its production method, which is characterized by: issuing authorization and processing of the electronic label according to the encoding and encryption rules; the electronic label issuance management system issues the label of its products according to the demand application of the manufacturer, and each commodity has a unique encoding serial number. The legality of the electronic label is verified by means of networked terminal scanning. Its characteristics are: universal and simple, easy to identify, simply impossible to imitate, and extremely safe, reliable and accurate.
2. Ticket anti-counterfeiting
In transportation and tourist attractions, fake ticket incidents occur repeatedly. In these fields, it is more urgent to apply RFID technology for anti-counterfeiting, and at the same time, it is also very convenient. For example, in railway stations, subways, as well as tourist attractions and other places where there is a lot of foot traffic, the use of RFID electronic tickets instead of traditional manual tickets both to improve efficiency, but also play a role in anti-counterfeiting, a multi-benefit. For example, in the competition and performance and other occasions where the ticket volume is relatively large, RFID technology for ticket anti-counterfeiting, not only no longer need manual identification, to achieve rapid passage of personnel, but also to identify the number of times the ticket is used to prevent the ticket is stolen out of the hand again, to do “times anti-counterfeiting”.
3. Document anti-counterfeiting
Internationally in the passport anti-counterfeiting, electronic wallet, etc. can be embedded in the standard passport cover or document RFID tags, the chip at the same time to provide security features and support hardware encryption. Domestic applications in this field have also formed a considerable scale, such as the promotion and application of the second generation ID card is a typical representative of this area, this technology will soon be widely used in the management of important documents issued.
4. Luxury anti-counterfeiting
Anti-counterfeiting electronic label has been widely used to many aspects, such as: medical, libraries, shopping malls, etc., but for some luxury goods, or relatively unfamiliar, because even a small part in some jewelry goods to do the relevant anti-counterfeiting electronic label, are only greatly obviously enhance the efficiency of jewelry enterprises, such as: inventory, point warehouse, in and out of the warehouse, and reduce the rate of theft only It is not particularly useful for the holder who buys jewelry. If the need is to add on top of this jewelry can continue to have tracking and positioning functions after the purchase, so that not only can customers wear jewelry with confidence in the future, even if accidentally lost can also be located in the first time to jewelry information. This not only let the customer have the full sense of security also can stimulate more people who have the ability to purchase luxury goods to purchase these luxury goods.
This kind of electronic label not only can be used in the jewelry, also can be used to many big brand of wine, top clothing protection, with people more and more will enjoy life, those who have the ability to have the conditions to enjoy these luxury goods will be more and more important to the protection of these items, believe in the near future, such an upgraded version of the electronic label will come into being and be widely used in life.
Petroleum and petrochemical, national grid, logistics, clothing and other fields can use RFID tags, as long as the items of value can be supervised with RFID tags, even if it is the transport of personal items. What is greeted here is not only a low-cost intelligent anti-counterfeiting product, but also an Internet of things era that can be applied to information-based real-time management.
RFID anti-counterfeiting traceability system at home and abroad has set off a new trend of anti-counterfeiting using electronic technology, especially RFID anti-counterfeiting, which has gradually started to gain importance in the application of middle and high-end products due to its advanced technology. Due to the successive meat and vegetable quality problems in China, the country also attaches great importance to meat and vegetable quality traceability, and traceability systems are being gradually promoted throughout the country. Traceability in high value-added industry products can also achieve effective and reasonable control of the quality of product suppliers.
Most industry users first of all have gradually become aware of the advanced nature of RFID anti-counterfeiting, in addition to the process of contact, due to the high cost of inputs can not be applied. Due to the high investment in RFID systems (generally one-time hardware and software investment to millions), and RFID tags cost more than two-dimensional code, printing and other anti-counterfeiting technology costs are still much higher.
The implementation of RFID anti-counterfeiting system can effectively reduce the one-time use cost of enterprises using RFID anti-counterfeiting. Software from a one-time investment to cloud computing software services for rent, and does not require a one-time investment in computer servers, network equipment and other hardware inputs, only the acquisition of the necessary RFID reading and writing equipment. It is expected that the one-time investment in system implementation will be reduced from one million to about 200,000. For certain industries, such as food, pharmaceutical industry, the need to be able to effectively track the quality, traceability. The application of RFID systems can ensure the exchange of high quality data in the food supply chain, the thorough implementation of source food tracking solutions and the ability to provide complete transparency in the food supply chain.
