RFID era is coming, driving the broad prospects of conductive ink

with the east wind of the Olympic Games and the WorldExpo, RFID (electronic tag) has gradually become an irreplaceable product for the printing and production of tickets for various large-scale events. The 70million visitors to the Shanghai WorldExpo have made RFID reach the highest point of its career, and RFID, taking advantage of the east wind, has entered the vision of ordinary people and become a rising star in the printing industry

in fact, RFID did not appear in the past two years. As early as 2007, when China began to replace the second-generation resident ID card on a large scale, RFID has quietly entered people's vision. The second-generation ID card is by far the largest RFID application, because the second-generation ID card is the application of RFID technology, and it is its built-in chip that makes it applicable in various fields

rfid features

rfid is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not need human intervention, and it can work in various harsh environments. RFID technology can identify high-speed moving objects and multiple tags at the same time

rfid is divided into low frequency, high frequency and ultra-high frequency according to different application frequencies; It can also be divided into passive RFID and active RFID according to the mode of energy supply, but no matter which type, its working principle is the same. A complete RFID system consists of two parts, a signal transmitter and a receiver

the author believes that the biggest feature of RFID is that it can record data and give feedback to the corresponding terminal. The recorded data can be rewritten repeatedly, and its shape is unlimited, and its size and shape can be changed, making it suitable for a variety of materials. It is doomed that RFID can be applied in various fields, such as packaging, clothing, food, logistics and so on

rfid application

rfid contactless chip design has made RFID successful in the application of large-scale event tickets. Tickets for the Shanghai WorldExpo can be checked without contact and alignment. Ticket holders only need to hold tickets and brush them within a distance of 10 cm from the reading and writing equipment to enter the site easily, which can meet the needs of a large number of people who need experience to verify their admission in a short time

after the two grand events, RFID also appeared from time to time in daily life. The electronic ticket system of the 19th Golden Rooster Hundred Flowers Film Festival is another application of RFID and statistics in the electronic ticket system. RFID technology is used to store all kinds of information on the ticket and the keys of the organizing committee. Users are also invited to carefully understand the information stored in the chip and embedded in the paper, effectively ensuring the anti-counterfeiting security of the conference tickets. When the spectators enter the venue, they can quickly pass the inspection with a flick of RFID electronic ticket machine. At the same time, the system will record in detail when the ticket holder enters the venue, seat area and other information. RFID electronic tickets have the characteristics of high reliability, tamper proof, anti detection and low cost, which fundamentally eradicate fake tickets. At the same time, the low-cost characteristics provide strong support for the promotion and popularization of RFID electronic tickets

tickets have become one of the largest applications of RFID, which has greatly promoted the development of electronic tag technology in China. Xu Dongying of Shanghai Huahong, a ticket supplier for the WorldExpo, once predicted that the high-frequency RFID application would increase at a rate of no less than 20% to 30% per year in the next few years, and the label printing business would also increase at the same rate

in addition, RFID has been applied to food packaging. It is reported that the bottle label of Changyu high-end wine is equipped with an electronic tag (RFID production), which inputs the information of the bottle from production to storage, logistics and sales. It can realize real-time dynamic tracking, and ensure the whole process backtracking of products and the rapid recall of problematic products. In addition, RFID can also realize the function of anti-counterfeiting. This has been confirmed by some liquor manufacturers. At present, Tuscany winery in Italy and Moutai (600519, Guba) in China all install RFID tags on the bottle cap to prevent counterfeiting, which can identify the authenticity and year at the dealer. Once the cap is opened, the label will automatically become invalid. The Dow pacxpert flexible packaging technology has been highly praised since its inception. It has the characteristics of global unique code, digital signature, anti transfer, anti duplication and so on. It adopts the metal antenna production and processing technology of fragile paper substrate. So far, Wuliangye (000858, Guba) has purchased tens of millions of qr2235 UHF electronic label chips for the anti-counterfeiting of Wuliangye wine, and has mass produced tens of millions of bottles of wine with RFID anti-counterfeiting labels, which are sold in the national market. This is by far the largest UHF RFID commercial project in China

obstacles faced by the development of RFID

although RFID showed its skills during the two major events, one of the important factors of retreating to the mountains and forests after the two major events was the cost. According to the current production process, the price of each RFID tag ranges from US $0.3 to US $0.6. Even at the cheapest $0.30, it takes about 2 yuan to convert into RMB. In general, except for high-end alcohol, I'm afraid there are not many products that can afford this price

in the final analysis, the reason why the cost of RFID tags cannot be reduced is still technology. Although they are called tags, the printing method of RFID is very different from that of traditional tags. Chip is the key of RFID, which is determined by its special structure and cannot bear the pressure of printing machine. Therefore, in addition to inkjet printing, the process of printing surface layer first, then compounding with chip layer and die cutting is generally adopted. There are three manufacturing techniques for Antennas: etching, coil winding and printing. RFID antenna printed with conductive ink is a new technology developed in recent years

printing conductive ink will also be the most ideal way to reduce the production cost of RFID tags. Not long ago, BASF, an ink manufacturer, announced that it had developed a metal ink for the production of flexible antennas for RFID tags. It is said that cypprint ink can replace the expensive and conductive printing materials used in the previous addition process, thereby reducing the manufacturing cost of RFID antenna

in addition, recently, fino Lantai launched a new UHF beltfid tag, which is designed for single tier applications, including consumer electronics, retail supply chain and clothing labeling

although currently in the market, the conductive ink market for RFID antenna printing accounts for only a very small part in the progress of integration and coherent technology. However, the author believes that as more and more manufacturers focus on conductive ink, the cost of conductive ink will continue to decrease in the future, and the application of RFID will also show explosive growth

rfid's future

now RFID has developed for many years, and the only factor that restricts it from moving forward is the cost, which has also ushered in a glimmer of dawn with the efforts of many ink manufacturers. 2011 is the first year for the RFID industry to enter the growth period, and it is also the beginning of the rapid development of the RFID industry. Ouyangyu, Secretary General of the China RFID industry alliance, said that as the most widely used technology in the IOT concept and the most mature business model, RFID will have a market size of more than 15.7 billion yuan next year and more than 20 billion yuan by 2012. It can almost be concluded that the RFID era is already in front of us, and the RFID era is coming
