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 the target object for item tracking and data exchange. RFID readers are usually divided into two different types, fixed RFID readers and handheld RFID readers.
Fixed RFID Reader
Fixed RFID readers
are generally equipped with 1-4 antenna ports, the number of antennas depends on the coverage required for the RFID application. Some applications, like file input and output, require only a small coverage area, so a single antenna will do the job just fine. Other applications with greater coverage often require multiple antennas to create the necessary coverage.
Fixed RFID readers only need to be fixed in one place and kept powered on, and data will be collected continuously. So, if you want to capture how many items go into your warehouse in a day, but don't want to manually scan each shipment, using a stationary RFID reader
is a great way to automate the process. Fixed RFID readers generally have a larger read range than handhelds and can monitor a larger area at a time.
Handheld RFID Reader
The handheld RFID reader
can also communicate with a host or smart device when reading RFID tags. Because handheld RFID readers are lightweight and battery-powered, they can be taken with you wherever you go. And compared with the fixed type, the handheld type does not need to be installed, and the RFID tag can be read just by opening the device. In addition, the initial investment cost is low, the application scenarios are more abundant, and the collection functions are more diversified.
