Application of anti-counterfeiting technology in printing and packaging engineering (Part 2)

v. IC card (integrated circuit card)

an integrated circuit is embedded or injected into a plastic card, and its internal operation can be carried out, so that the card has the functions of storage and microcomputer. This card, also known as integrated circuit card (IC card), was invented by the French in 1974. Its capacity is much larger than that of the magnetic card. The storage capacity of the huge market demand products produced abroad can reach several thousand bytes. Photos, blood types, fingerprints and other personal data for identification can be accommodated. Because of its good confidentiality, it can run independently without relying on the database, so it is very practical. Moreover, the memory can be divided into multiple application cells to realize multiple uses of one card

due to the low cost of IC card and the continuous improvement and perfection of its anti-counterfeiting performance, it is likely to replace the general magnetic card as most cards such as credit card, ID card, driver's license and passport, and can be extended to the anti-counterfeiting of various valuable bills and valuable commodities

VI. smart cards

the IC card has an encryption logic circuit inside, which is called smart cards. In order to deal with fake credit cards, europay international, MasterCard and visa credit card companies cooperate to launch smart credit cards and publish their BMV standards. A smart card is a smart card placed on an ordinary credit card. A smart card uses a chip that can store a large amount of information and is not easy to be counterfeited. Because the production of chips is high-tech and large investment, and the card has an encrypted logic circuit, it can restrict the hands and feet of forgers. In addition to using this card as a credit card, the cardholder can also use it as a portable insert card, a long-term customer card in a store, or even a ride card for taking public transport, so as to achieve the purpose of multiple uses of one card

VII. Laser card

has been applied in Europe, America and Japan. Its reserves are larger. At present, the maximum capacity of a card can reach 6.6m bytes. Because the data on the card cannot be rewritten, and the card itself is durable, high-temperature resistant, and not afraid of magnetic field, electrostatic interference and X-ray radiation, it is popular. Laser card has three application forms: hardware encryption, software encryption and human body feature record encryption. Unlike the IC card, this card has a strong self-management function and is relatively easy to use. Since the information is exposed on the card, once the forger gets a set of reading and writing devices and software, it can be decoded, making it lose its anti-counterfeiting function. If the IC card and laser card are comprehensively used to develop a new composite card, its anti-counterfeiting performance will be better

VIII. Radio frequency identification technology

this technology appeared in the mid-1980s. Its principle is that it uses electromagnetic induction, radio or microwave for non-contact two-way communication, and achieves the purpose of identification by exchanging data. The exchange of data and information occurs between the electronic tag inside the identified object and the reader/writer that sends instructions. The most relevant information in the electronic tag because the electronic tag is built-in, even if the environmental conditions are bad, the application of RF card will not be affected. This technology was first used in the remote control and monitoring of wild animals. Scientists placed electronic labels on animals to understand the area and scope of animal activities. Because the reader/writer has the ability of simultaneous recognition, it can carry out large flux recognition, and is widely used in many fields. In the marathon race, because there are too many people and different departures, it will be unfair if there is no accurate timing device. Therefore, experts designed such a way: Athletes tie RF cards on their shoelaces, and place small pads with micro antennas at the starting line and the finishing line of the competition. When athletes cross the pads, the timing system receives the signals from the RF cards carried by athletes, and records the time. This device can also be used to record fingerprints Palmprint or facial features are processed by digital h, and then stored in the RF card to better identify the identity. In the 1996 Olympic Games, athletes and officials carried radio frequency cards containing palm information with them. When they want to enter a safe area, they must put their right hand on the scanner. When the three-dimensional image retrieved by the system is consistent with the person, and the person carried into the area, this technology is used in many automatic toll collection highways in Europe and America. The vehicles frequently traveling on the expressway have installed RF cards on the vehicle in advance. When it passes through the toll station, it does not need to queue up for payment, but passes directly. Because a reader is installed at the toll gate to record the travel time and distance of the vehicle, and the highway fees are automatically transferred from the user's account

it is reported that RFID (radio frequency identification), known as "electronic tag", is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals without manual intervention. As a wireless version of bar code, RFID technology has the advantages of waterproof, antimagnetic, high temperature resistance, long service life, large reading distance, and encryption of data on the tag Storage strain has the advantages of elastic deformation, larger storage data capacity and free change of storage information. Its application will bring revolutionary changes to retail, logistics and other industries

relevant departments predict that by 2008, the market scale of radio frequency identification (RFID) technology used to track goods in the retail supply chain will grow to nearly 1.3 billion US dollars. RFID advocates believe that this technology is closely linked with the electronic supply chain and will most likely replace the barcode scanning technology in the near future. For example, RFID inventory tracking system refers to the automatic storage and transmission of component specifications, serial numbers and other information by attaching RFID tags to pallets, packaging boxes or components. RFID tags can transmit information to RF card readers within 10 feet, so that warehouses and workshops no longer need to use handheld barcode readers to scan the barcode of components and products in process one by one, which reduces the occurrence of omissions to a certain extent and greatly improves work efficiency. RFID advocates believe that the move could significantly cut costs and clear up obstacles in the supply chain. The demand for this technology exists in every link of the supply chain. Wal Mart has said that the company will use pallet and cargo box level RFID for three basic intelligent configurations: mainframe, microcomputer and printer by January next year, which will urge its upstream suppliers to carefully study the products using RFID and take it as part of the external transportation link. The retail giant metrogroup recently announced that this year the company will fully promote RFID technology in retail stores and distribution centers

recently, the National Standardization Administration of China announced the formal establishment of the "electronic labels" national standards working group, which is responsible for drafting and formulating China's relevant "electronic labels" national standards, so that they not only have China's independent intellectual property rights, but also are compatible with the current international standards, so as to promote the development of China's "electronic labels" into the track of standardization and standardization
