Application Of RFID In Logistics Storage

RFID is a kind of new information technology, with which the contactless rapid transmission of data and information can be realized. At present, RFID is broadly used in the fields as manufacturing, forge-proof, animal identification, traffic card, logistics and supply chain management etc., which has brought about great technical renovation, especially in logistics field. It dramatically enhances logistics data collection speed and as well as the working efficiency. However, as the cost for RFID tag and RFID reader is rather high and the lack of national standard of RFID electromagnetic wave frequency, few enterprises have adopted it. As a result RFID technology has not been really adopted and spread. But with the falling of RFID tag and RFID reader cost as well as the formation of the national standard, it is going to be a favor for the logistics enterprises.RFID is the technology that RFID tag transmits data in wireless way, automatically identifying the objects through radio wave and obtaining data, no need for straight line of sight between the object and the reader, and it is a kind of read-and-write technology. The principle of RFID is to use wireless electronic magnetic wave to transmit data, and to use low-frequency, high-frequency, ultra-frequency, microwave etc under different condition; taking the advantages of them; accomplishing the mission of rapid data-collection. Moreover, as it is dirty-resistible and reusable, RFID technology is seen to be more and more popular.As traditional storage begins with stock-in and ends with stock-out, in between there is a series of operations like inspection, Stock-taking, stock article locating and stock-out sorting that are all accomplished by manpower. Such operations is time-consuming, low efficient, fallible, slow informing, and cannot adapt to the development of modern logistics storage, and therefore it badly calls for a new kind of logistics information technology to substitute traditional mode. And RFID technology is the key to such a problem. The application of RFID, can advance the efficiency of stock-in inspection, achieve rapid article-locating, save Stock-taking time, and improve stock-out sorting efficiency.The study of RFID at Shenzhen Institute of Technology training room, has explored an immature solution to application of RFID in logistics storage. The solution includes stock-in and stock-out program design, RFID configuration, RFID auxiliary device configuration, RFID and relative devices cost analysis, etc., and is attempted to be used for material storage of HONGKONG CHOW TAI FOOK JEWELLERUY CO.,LTD to optimize the operation efficiency. The success of such attempt will definitely bring an overwhelming effect on logistics storage field.Just as other information technology, RFID also confronts a lot of network and computer security problem. Moreover there is also RFID self-security problem, such as reader internal security problem, RFID access security problem, etc. To solve these problems, besides applying cryptographic technology, hash switch, Kill command and so on to protect the security of data, we should also continuously improve the security of the devices.
