Library business: a space for RFID technology to play its role

library is a special field, and its business model is also different from other fields. In this era of information explosion, books and various forms of media products are also increasing. It is not easy to manage these complicated data in an orderly manner. From another point of view, the reader group of the library is increasing every day, and today's readers have higher and higher requirements for the library. The library must improve the overall service quality to meet the requirements of today's demanding readers

the business of the library requires an efficient and convenient management system. Therefore, the application of many new technologies starts from the library, such as bar code + magnetic stripe technology. One of the earliest application fields is the library, and many libraries still use this technology for book management. However, with the development of the times, this technology has become increasingly unable to meet the needs of library business. In contrast, RFID technology is increasingly accepted by libraries and has become a new helper in library business management

there are several advantages of using RFID to assist the business management of the library. First of all, RFID technology does not need visibility. Managers can clearly understand the situation of books entering and leaving the library and the location of each book in the library without naked eyes. This can make the procedures of borrowing and returning books simpler, and also make the inventory of books easier. For those readers with bad records, the system can also send a prompt in advance. Therefore, at the same time, RFID system can detect multiple targets at the same time, instead of the traditional bar code technology, which can only complete the scanning and registration of one book at a time. This has further improved the efficiency of library business

at present, many libraries at home and abroad have adopted RFID technology for management. For example, the Douglas County Library in Colorado, USA, installed Vista sorting system provided by ITG company (Integrated Technology Group) in the rubber tree public library with low accuracy of resistance strain gauge and fixed strain gauge inside its lone sensor. The core technology of this system is RFID tag. The sorting system can help the library to put the books dropped within 24 hours back on the shelf. Bob pasicznyuk, director of the Digital Service Department of the library, said that the area of the lone tree library itself is not large, but the library has always hoped to adopt the automatic data sorting and processing system rather than spend too much money on large-scale equipment. At present, the lone tree library has developed a plan to track the benefits of this automatic sorting and processing system. The tracking results show that the results of the implementation of the system are very satisfactory: after the application of this system in the whole library system, about 66% of the staff's time has been saved

another example is that the library of the Max Planck Institute of European legal history, which collects up to 320000 documents, also uses RFID system to manage books and archives. It is reported that the museum is the first institution in this industry to adopt this system. Sigrid amedick, the librarian of the library, said that RFID tags can provide safe and long-term data storage. These specially treated labels use pH neutral adhesive, which is bonded to historical documents and periodicals and books often read in the library. The adhesive designed in it will not degrade any label sticking data. Amedick said that the new durability label is very important for the Max Planck Museum, because there are many in the museum. This is because with the continuous development of new materials and new processes, the literature will be updated every 4 to 5 years. Bar code labels have been the standard technology used in the library for many years, but they are no longer suitable for the current needs, because these bar code labels may fall off books after many years. In addition, if bar code labels are used, the library also has to affix an electronic supervision (EAS) label on the books to give an alarm when the assets are taken away without authorization. The RFID tag used this time can provide EAS function, so the number of tags that must be pasted before can be reduced by half. The memory of this tag is 2048 bytes. It is said that after the application of RFID tag system, the workflow of the library has accelerated by 25% to 50%

in China, there are not a few libraries that apply RFID technology. For example, Shenzhen library is a foreign library with an area of more than 30000 square meters and a construction area of 50000 square meters. Its collection of books has reached 4million. Shenzhen Library has created many firsts. It is the first free public library in China; Anyone can apply for a library card as long as he has an ID card, not limited to local residents; It is also the first library in Shenzhen to adopt RFID technology. At present, Shenzhen library receives 3million readers annually, and RFID technology helps them easily deal with nearly 10000 readers

Shanghai Changning District Library is the first library in East China to adopt RFID intelligent management system. The RFID system of the library is provided by Shanghai Afadi company. The RFID intelligent collection system of Afadi library includes: self-service borrowing, librarian workstation, label conversion, query, shelving and inventory system, 24-hour self-service book return, intelligent detection and other equipment. RFID system layer includes RFID device layer, controller layer, middleware layer and management application layer. The RFID system of Shanghai Changning District Library, which has been running for four months, has progressiveness in technology and architecture and functional expansibility, realizes the seamless link between horizon and ILAS management platforms, supports the IC card of Shanghai Center Library and the RFID reader card of Changning District Library, and continues to participate in the circulation of Shanghai center library. It is reported that Shanghai Afadi's Library RFID intelligent collection management system uses Shanghai belling RFID chip bl75r04 2kbit, which conforms to the iso/iec15693 wireless interface standard 2kbit electronic tag chip, which can be made into electronic tags or contactless cards, with a reading and writing distance of 60cm, and a data transmission rate of 26.5kbit/s, making the recognition rate of 50 cards per second. The on-chip 2K bit E2PROM is divided into 64blocks. The data retention time is more than 10 years, and the number of reads and writes can reach 100000. According to huangjihua, the managing director of Shanghai Afadi smart tag system technology Co., Ltd., the RFID solution provided by the company for Hangzhou library system is also being implemented

in the era of knowledge explosion, library is an important place for people to learn and seek knowledge, and RFID technology is also playing an increasingly important role in the field of library with its unmatched advantages. RFID technology has begun to play a big role in the field of libraries, and this trend will be further extended and deepened in the future
