How to choose the right hardware for an RFID document tracking system?

Choosing the right hardware for an RFID document tracking system is critical.

UHF RFID system consists of UHF RFID reader, UHF RFID antenna and UHF RFID tag. In the RFID document tracking system. The RFID tag  attach to the document box or document bag.

The RFID system sends data to a tracking system with RFID readers and tags, forming automatic data collection. The choice of different RFID devices will have a great impact on the actual application effect of the entire project.

In RFID projects, misreading and low recognition rate are the most common problems for users. And these problems can be solved by choosing appropriate RFID equipment. Here are our recommendations on how to choose the right RFID equipment for your RFID document tracking system.

How to Choose the Right UHF Tag for an RFID Document Tracking System

When managing files, you need to identify how many files there are in a filing cabinet. Even to the point of how many files there are on each floor. The thickness of the file bag is different, and some are as thin as 1-2mm. In this case, we need to choose RFID tags with good reading performance. When two ordinary RFID tags  put together, the performance becomes very poor. Larger changes in tag frequency occur when coupling between tag antennas occurs.

How to choose the right UHF RFID antenna

When it comes to UHF RFID antennas, in actual RFID applications, we often don’t know how to choose. The most important characteristics for selecting an antenna are. Polarization direction, antenna gain, beam angle, operating frequency band, mechanical size and application environment. In the management of files and archives. We need to choose antennas with a very uniform field distribution.

Many people would think that the reader and the near-field antenna of the reader should identify by the near-field antenna. In fact, this is not true. RFID document tracking systems should use long-range RFID antennas. In many RFID document tracking projects. The antenna installed inside or below the filing cabinet and needs to read from a distance of 15-30cm. The conventional near-field antenna can read up to 30cm under the condition of the reader’s maximum RF output. And the RFID tag should have good performance. So near-field antennas cannot guarantee 100% accuracy.

How to choose the right UHF RFID reader

We should consider the following points when choosing the right RFID reader:

• Frequency: Should be UHF (860-960MHz)
• Antenna ports: 2, 4, 8 or more ports
• Communication interface: Wifi/RS232/Ethernet/POE
• Reading speed/reading distance

You can choose according to your actual needs.

How to choose the right RFID cabinet

Attentions

At present, there are many types of smart filing cabinets on the market with different functions. Some don’t work very well. If a document not stored in the specified location. The actual location information of the file cannot be found. And only the original registered location information can query. So the location function is useless. Choose intelligent filing cabinets combined with RFID technology. Which can quickly locate, count, and automatically identify in batches. In this way, real-time monitoring and intelligent management of the whole process of borrowing, returning, checking and depositing can be realized. The RFID intelligent file cabinet can update the file location information in real time and realize on-site supervision.

To Sum Up

RFID technology has the characteristics of non-contact data collection, good data security. Plus fast reading speed, large capacity of RFID smart labels, long service life, and reusability. We widely use it in archives, libraries, government and enterprise units, schools and other fields.
