UHF Library Tag: Enhancing Book Management Efficiency

In modern library management, UHF library tags are becoming an important tool for enhancing the efficiency of book tracking and management. These tags not only simplify the circulation process of books but also significantly improve inventory management accuracy. This article will explore the key features of UHF library tags, the impact of application environments, and future development trends.

The Basic Types of UHF Library Tags

UHF library tags are mainly divided into passive RFID tags and active RFID tags. Passive RFID tags are the most widely used, with operating frequencies including low frequency (LF), high frequency (HF), and ultra-high frequency (UHF). Among these, ultra-high frequency (UHF) tags are widely used in libraries due to their long-distance reading capability and high data transmission rates.

Passive RFID tags mainly come in two types: inlays and hard tags. Inlay tags are usually very thin and can be adhered to various materials, making them suitable for managing most library books. Hard tags are made of durable materials such as plastic, metal, or ceramic and are typically used in applications that require higher durability. Although hard tags are more durable, they are also more expensive. In contrast, inlay tags are the preferred choice in libraries due to their low cost and good applicability.

The Impact of the Environment on the Performance of UHF Library Tags

In a library environment, UHF library tags performance may be affected by various factors. Metal and liquid environments are two major sources of interference.

Impact of Metal Environments

Metal shelves or devices in libraries may impact the performance of UHF library tags. Metal can cause parasitic capacitance and electromagnetic interference, detuning the RFID tag and reader. This interference can affect the reading distance and reliability of the tags, especially in areas with a high presence of metal. Therefore, to ensure normal tag operation, libraries need to consider these potential interference factors during design and layout.

Impact of Liquid Environments

Liquids can also affect the performance of UHF library tags. Liquids absorb radio frequency signals, reducing the reading effectiveness of the tags. Although liquids are not as common as metals in libraries, their presence during book cleaning or maintenance can still cause signal attenuation. Therefore, libraries need to pay special attention to the performance of UHF library tags in liquid environments when selecting and applying these tags.

Future Development Directions of UHF Library Tags

With technological advancements, UHF library tags are developing towards green environmental protection, anti-counterfeiting, anti-transfer, and diversification of raw materials. Future tags will use special inks to directly print antennas on various materials and then bind chips. The chips in these tags can have globally unique coding information that only authorized manufacturers can read. This coding method ensures the uniqueness of the tags and prevents information copying and transfer, thereby enhancing the security and reliability of book management.

In addition, future tags will focus more on environmental protection and user-friendliness. The new tag materials will not only prevent reuse but also quickly break apart when torn to ensure they cannot be reused. Using special adhesives can effectively prevent second heating transfers, further enhancing the anti-counterfeiting capability of the tags.
