Optimal Library Inventory System Using EMID Technology
This paper proposes an optimal library inventory system which is based on electromagnetic identification (EMID) technology with the advantages of using electromagnetic (EM) tag and radio frequency identification (RFID) tag. The proposed system is constructed by four processes, including deciding the tag type, finding the optimal tag location for a book, testing the tag readability for multi layer bookshelves, and connecting a couple of multi layer bookshelves with multiplexers and updating the tag reading status in the database of the computer terminal. The proposed system is tested at the library of Cheng Shiu University in Taiwan. The quality and quantity of one side and two side of antennas applied in reading EMID tags with different time intervals and locations have been tested in the study. According to the experimental results, the designed library inventory system can authenticate the location of a book automatically and can benefit administrating librarians with the capabilities of decreasing the library inventory processing time and reducing the possibility of the books being misplaced.
