In the daily operations of a company, fixed asset management is a critical task. Traditional methods often rely on manual record-keeping and barcode scanning, which can be inefficient and prone to errors. The application of RFID (Radio Frequency Identification) technology has significantly improved the efficiency of fixed asset management. This article focuses on explaining how RFID readers and tags function in the fixed asset management process, and briefly compares their advantages over traditional management methods.

Overview of RFID Technology

RFID technology automatically identifies objects and retrieves relevant information using radio waves. It consists mainly of RFID tags, RFID readers, and a back-end data system. The tags are attached to fixed assets, storing unique identification information, while the reader is responsible for reading the data from the tags and transmitting it to the management system.

RFID tags are categorized into active and passive tags. Active tags have built-in batteries, allowing them to actively transmit signals and work over longer distances. Passive tags, on the other hand, do not have a power source and rely on the signal from the reader for energy, making them more cost-effective and suitable for large-scale asset management.

How RFID Tags Work

RFID tags serve as the “electronic ID” for each fixed asset, consisting of a chip and an antenna. The working principle of a passive tag is as follows: when the reader emits a radio frequency (RF) signal, the tag’s antenna receives the signal and converts it into electrical energy to power the chip. The chip processes the data and transmits the stored unique identification code and other information back to the reader through the antenna. Active tags, with their built-in batteries, can transmit signals over longer distances without relying on the reader’s power.

This contactless identification technology enables RFID tags to be used in complex environments and allows for bulk automatic identification, making them ideal for managing large quantities of assets.

How RFID Readers Work

The RFID reader serves as the data collection terminal in the system, and its main working process includes:

1. Signal Transmission: The reader emits radio waves through its antenna. When a passive tag enters the signal range, its antenna receives the signal, converts it into energy, and powers the chip. Active tags, in contrast, automatically respond to the signal.

2. Data Reading: The tag’s chip transmits the stored information back to the reader via the antenna. The reader can read data from multiple tags simultaneously.

3. Data Transmission: The reader sends the collected tag information to the back-end management system, where the system updates the asset data in real-time.

The RFID reader does not need to be aimed directly at each tag and can read data over long distances and in bulk, greatly improving the speed and accuracy of asset inventory checks.

Application of RFID Technology in Fixed Asset Management

The collaboration between RFID readers and tags significantly enhances the efficiency of fixed asset management:

• Quick Inventory: Using handheld RFID readers, large volumes of assets can be scanned over a short period, allowing for automated inventory without the inefficiencies of manually scanning each asset.

• Real-Time Location Tracking: Fixed RFID readers can be installed in key areas to monitor the movement of assets in real-time. As assets move, the system updates their location data instantly.

• Lifecycle Management: RFID tags can store information about the asset’s condition, maintenance schedules, and more. When the reader scans the tag, the system automatically updates the data, helping companies better manage the usage and maintenance cycles of their assets.

Advantages of RFID Technology Over Traditional Management

1. Increased Efficiency: RFID systems can read multiple tags simultaneously, reducing manual intervention and the time required to scan each asset individually, thus improving asset inventory and management efficiency.

2. Data Accuracy: RFID technology minimizes errors caused by manual input and operations, ensuring higher accuracy through automated data collection.

3. Real-Time Updates and Monitoring: RFID readers can monitor asset status in real time, reducing the risk of asset loss and providing quick responses to changes in asset movement or condition.

4. Cost Reduction: By automating management, companies can reduce labor costs and extend asset lifecycles through optimized maintenance schedules, leading to lower overall costs.

Conclusion

Through the efficient collaboration of RFID readers and tags, RFID technology provides an automated, accurate, and efficient solution for fixed asset management. Compared to traditional asset management methods, RFID systems greatly enhance efficiency and reduce human errors, enabling companies to better track and manage their assets. In the future, as RFID technology becomes more widespread, fixed asset management will become increasingly intelligent and automated.
