Across the globe, libraries are renowned as hallowed havens of knowledge and their role in nurturing human intellect explains why they are highly regarded in our society. By incorporating different technologies, readers, and librarians can now bid goodbye to the laborious manual practices that resulted in never-ending queues and lost books. Thanks to RFID technology, library-goers can now locate desired books and check out at the reception with just a simple tap. Today, we center our piece on customized RFID systems for libraries and the resulting impact of their use.
RFID Library System.
RFID library systems are advanced tracking systems that communicate wirelessly using special electromagnetic fields. The requisite hardware that allows libraries to implement RFID tracking includes an RFID tag and a suitable scanner. The wide array of learning materials found in libraries e.g. books, audiobooks, DVDs, and manuscripts are tagged with RFID labels. The labels are programmed with publication as well as author details for hassle-free identification.
Automatic readers then pick up the harbored data and display it to the attendants or visitors, thereby stamping out manual scanning. This contributes to shorter or zero queues and saves a significant amount of time.
How RFID Works in Libraries?
Although RFID may sound complicated, it is in reality a simplified and fast process. Wireless communication is the basis for RFID library management and the resources needed are relatively affordable and quite dependable. When rolling out RFID, libraries follow different implementation strategies. For instance, a library can deploy RFID as the primary technology for self-checkout services. This option allows you to borrow and return library items without necessarily having to queue for a librarian to serve you.
The self-checkout station or kiosk consists of an in-built reader, which activates the tags attached to any library item. As you place the book on the kiosk, the reader powers the tag prompting the tag to transmit the distinct identification information to the reader. Within a fraction of a second, the system matches the identifier with the corresponding book record in its database. It swiftly retrieves details such as the book’s title, author, due date, and availability status. These details are displayed on the kiosk screen, allowing you to confirm the checkout. To return the borrowed book, you simply place the book in a designated return slot or on the library counter. An RFID reader nearby reads the tag’s identifier and communicates with the library system to update the book’s status. The book is marked as returned and immediately removed from your account. This process occurs quickly and accurately, making the return process efficient.
