Development and application status of RFID

what can connect the World Cup football match, razor blade and lost luggage? They are all potential users of a rapidly developing product tracking technology, namely RFID technology. Due to the large-scale investment of Metro Group and the alliance and cooperation of many enterprises, such as Siemens, Intel, SAP or Microsoft, RFID technology has gradually become a hot topic

rfid development and application status quo

in the supermarket, it is really tiring to take out the goods one by one from the fully loaded shopping car. Who can do it faster? Is it faster for customers to pick up and place goods, or is it faster for cashiers to pick up items and wait for checks to be paid? In the near future, people can walk forward with goods more calmly and freely than before, because using RFID Technology (radio frequency identification technology), all goods can be identified at one time, and payment and collection can be implemented

how does this technology work? The RFID tag is equipped with a chip and a tiny antenna. Most of the tags are placed on self-adhesive plastic film or paper tape. The surface of the label is sometimes less than 1.5cm2, with a thickness of about 0.3mm. The memory in the chip can store up to 10000 B of information about products, logistics and production. The distance between the scanner and the label is allowed to reach 1.5m (adjustable according to different models and environmental conditions). The principle of this technology is not novel, but because the label is very thin, it can be placed in the outer package, and the production cost of the chip is low, so it has been widely used

advantages in logistics

from the perspective of logistics, chips have great advantages. The data can be supplemented, changed and deleted at will. The chip can store much more information than the barcode, and there is no need to check the access data information visually. And it can access the information of multiple transponders at the same time. Its main advantages are: goods and their data are in the same location at the same time, so RFID technology is needed in the place of identification, transportation and storage. In this way, the rapid sorting and inventory of commodities can be realized in the logistics and storage area, and the rapid identification and transportation can be achieved in the airport, and the purpose of commodity security and theft prevention can be achieved

this technology can be well applied to the procurement of spare parts. Even if there are many kinds of spare parts in the automotive industry, the spare parts can be correctly identified after 10 years. RFID technology has been well used in the management of containers and pallets. With this "rewritable" label, you can avoid the trouble of uncovering old barcodes and pasting New barcodes every time. Therefore, Paul Cramer, located in herzebrock clarholz, reached a cooperation intention with Schreiner logi data, located in Munich, as early as the beginning of 2002, in order to optimize the internal logistics system and cargo circulation, and equip the Cramer CRI pallet series with RFID technology

a new EU regulation also promotes the application of RFID technology. Since 2005, food manufacturers have required their food to be well tracked repeatedly. This can be easily achieved through this technology. The basic tree industry environmental protection announced that the annual decline in apparent consumption of steel and domestic steel offset each other

use has become a reality

at present, there is a good trade momentum in the trial stage. But people have expressed dissatisfaction with the decline in profits in recent years. "In the future, technological innovation will become the main competitive factor in this industry. Through the storage technology of the future store initiative, met tensile testing machine is an extremely widely used testing machine, and RO group is committed to promoting the modernization of trade business." Confirmed by Dr. Hans Joachim Koerber, chairman of Metro Group. Using labels in the field of commodity circulation should reduce the difficulty of the whole process from the manufacturer's tracking of commodities to the customer's payment. In addition to the purpose of commodity safety and theft prevention, we should also reduce the labor intensity of inventory work

only in the scope of Metro Group (located in Rheinberg), RFID tags have shown their good practicality since 2003. This supermarket has simply become an experimental site for 40 partners - from label manufacturers such as Feig electronic, smart balance manufacturers such as Bizerba and Mettler Toledo, to Liebherr's talking refrigerator. In this field, the collaboration between software manufacturers such as Nestle, kraft and Microsoft, sap and service providers is excellent. About 1700 different goods in the supermarket carry RFID tags. With this label, people can find out the origin at any time and have a good grasp of the supply chain from Metro central warehouse in Essen to Rheinberg supermarket. We should not only provide customers with product information such as price, manufacturer, shelf life and weight, but also use RFID technology to automate the purchase work. For this reason, the company sets RFID tags for the goods supplied to the future store station of Rheinberg central warehouse, and reads the relevant contents after arriving at the supermarket. After the goods continue to be transported to the point of sale from the supermarket warehouse, the relevant information is read again to confirm that the goods have been removed. From November, 2004, all pallets and outer packages of about 100 Metro suppliers will be RFID tagged

From July to November 2003, kaufhof Warenhaus Ag carried out large-scale experiments in two logistics enterprises and two branches, and achieved positive results. With the help of RFID tags, the company can track Gerry Weber's textile products in all links from logistics, goods preparation and deployment to collection. At the cash register, the receiver is finally separated from the goods. Siemens business service coordinates the pilot project involving about 20000 RFID chips, while Siemens a&g assembles information reading and writing devices to the shopping malls and warehouses of Neuss and the department stores of wesel. UWE quiede, the project leader in charge of assembling RFID technology in department stores, talked optimistically about the application prospect of RFID Technology: "Where goods need to be identified, RFID technology needs to be used. Therefore, at the entrance of digital products and mobile phones, the data collection of the pallet containing 60 goods can be completed in an instant. We obviously feel the saving of time when checking or checking in the branch store. Mall personnel also see another way to use, that is, the salesperson can quickly and comprehensively obtain product information.

the 2006 World Cup is enough." The organizing committee also wants to equip 12 stadiums in Germany with RFID technology. At present, they are cooperating with Philips Semiconductors to carry out this work. The staff of the organizing committee want to make it more difficult to forge tickets by using personal RFID tags and electronic admission technology, so as to ensure that only legal personnel can enter the venue. Such a system should be able to prevent violence and prevent the black market trading of tickets

the road to mass production

at present, the cost of manufacturing RFID tags is still relatively high. According to different use occasions, the price of tags is between 0.5 ~ 1.50 euros. In order to make the label as the information carrier of each commodity, the production cost of the label must be greatly reduced. Only by reducing the price of each label to 0.05 euros, it is possible to make such labels available in large numbers. "The price of a 0.5 Euro label is still too high." Quiede said, "but we will continue to carry out this work."

it will take time to completely abandon the practice of using bar codes. "Every system has its rationality, so RFID tags and bar codes will continue to coexist." Christoph Gebauer, head of the Sales Department of Schreiner logi data company, firmly said, "in the past few years, bar codes have also continued to develop. For example, two-dimensional codes and data array codes can also provide richer information in a very small volume. Nevertheless, the development space of RFID technology is still huge, and it has opened up a new field of use." When quoting wireless receiving technology, it is also necessary to clarify the specific details of the actual work, such as how to ensure that the required data information can be obtained

transparent customers

because there are many opportunities to store data information, the issue of how to protect data information has also been put on the agenda. Although people can protect RFID technology from black market trading and plagiarism, it still opens the door to abuse. Usually, this kind of label is set on the price tag and removed after the customer pays. However, since it does not need people's visual inspection, it may be hidden or placed inside the packaging box. When using bank cards in combination (about 25million German citizens regard them as their avatars), it is possible to make customers' shopping behavior and other information public. Therefore, the Consumer Association foebud in bielerfeld has announced that it will develop a data personalization device that can detect and find hidden signal receivers

RFID tags are very useful and easy to set in many occasions of logistics. Even though it will take time for a large number of uses, the topic of RFID is in the ascendant. As Mr. John Davies, vice president of Intel solution market development group, said, "the application of RFID technology is not only the popularization of a technology and the development of a business process, but also a new mainstream technology direction
