Introduction to different classifications of RFID readers

The RFID reader is the core of the RFID system. It is a device that communicates with RFID tags by sending and receiving radio waves. It can automatically identify target objects for item tracking and data exchange. RFID readers are usually divided into two different types, fixed RFID readers and handheld RFID readers.

Fixed RFID readers are generally equipped with 1-8 antenna ports, and the number of antennas depends on the coverage required by the RFID application. Some applications, such as file input and output, require only a small coverage area, so one antenna can do the job well. Other applications with larger coverage areas usually require multiple antennas to create the necessary coverage.

The fixed RFID reader only needs to be fixed in a certain place and kept powered on, and it will continue to collect data. Therefore, if you want to collect how many goods are in the warehouse in a day, but do not want to manually scan each time the goods are purchased, then using a fixed RFID reader is a good way to automate the process. Fixed RFID readers generally have a larger reading range than handheld RFID readers, and can monitor a larger area at a time.

The handheld RFID reader can also communicate with the host or smart device when reading the RFID tag. Because the handheld RFID reader is lightweight and battery-powered, you can take it with you wherever you go. And compared to the fixed type, the handheld type does not need to be installed, just open the device to read the RFID tag. And the initial investment cost is low, the application scenarios are more abundant, and the collection function is more diversified.
