Based On The Design And Implementation Of Rfid-library Loan System

RFID has been around for over sixty years. A distinct advantage to RFID is the automation of processes. Generation 2, with its stable operations in read rates and information exchange allows ease of operation. With extra stability, great gains in processing speed can be made using automated sorting and material handling by limiting or in some case eliminating human invention. Gen 2 allows the dozens of individual objects within a group to be uniquely identified at the same time because backscatter is controlled; previously this was an intermittent problem. Backscatter control results in very stable reads by allowing multiple objects to be differentiated within the electrical scanning field. RFID is a means of uniquely identifying an object through a radio link. A reader also called an interrogator communicates with a tag, called a transponder. Each item has a unique identification code. Data between the tags and the readers are exchanged via radio waves and no direct line of sight is required for the transaction to occur. The reader requests data from the tag, or processes the signal being emitted by the tag, decodes the transmission and transfers the data back to the computer system. The type of tag determines how the tag will respond to the reader.The computer may do various tasks to process the data such as record the reading, look up the tag ID in a database to direct further action or direct the interrogator to write additional information to the tag.Book processing, which is based on barcode technology , also is more complicated, the need to manually open the book's title page and find the location bar code for scanning, and borrowing is less efficient. Meanwhile, the barcode is easy to damage, fouling weak. Frequent occurrence of damage could not be read bar code data situation, the book also affected by the efficiency, but also affect the reader's satisfaction of the library. The combination of both technologies can accelerate the circulation of books and improve staff efficiency. This article is based on RFID library lending system of research, presents a viable solution.
