Libraries have gotten by with barcodes for several decades. Barcodes are used as item tags, library ID cards, and more for data collection. But today, many libraries embrace RFID technology to seek efficiency, faster inventory management, and improved security. Why are modern libraries shifting from barcode to RFID? In this article, we will go over the difference between these two technologies.
Technology
RFID stands for Radio Frequency Identification which uses radio waves to communicate with RFID tags and readers. RFID tags contain a microchip and antenna to store and update more complex data, like borrowing and returning history, security information, etc. Barcodes consist of a series of parallel black lines and white spaces of varying widths to encode information. The barcoding technology requires a barcode scanner to read the barcode, convert it into a digital signal, and retrieve the associated data from a database. The barcode itself does not store detailed information.
Efficiency
No need for precise alignment, RFID is well known for its ability to scan multiple items simultaneously at a higher accuracy rate. This is an unbeatable advantage for faster self-checkout service during peak times and streamlined inventory management at libraries. While the barcode scanner requires direct line-of-sight for scanning and only captures each code individually. It is time-consuming and may cause a high error rate due to manual operations.
Barcode has significant security limitations since it doesn’t have inherent security features, meaning that it should rely on additional systems like gates to safeguard the library materials. RFID allows for greater security than barcodes, which integrates anti-theft mechanisms, such as alerts if an item leaves the library without being checked out.
Cost
Barcoding is a very low-cost technology that is simple to implement and maintain, which is ideal for libraries with budget constraints. With RFID, the initial setup costs are high since RFID tags and readers are more expensive than barcodes. However, the long-term savings in labor costs and efficiency may offset initial expenses.
RFID is ideal for libraries with requirements of prioritizing efficiency and automation, while, barcodes are better for smaller libraries with limited budgets and simpler operational needs. Still now, both technologies often coexist in hybrid systems depending on the library's requirements and constraints.
