RFID readers don’t all look or act the same. While some are mobile, others are fixed. Each sort, though, have their own benefits and drawbacks, depending on what application you’re using them for.
What are Fixed RFID Readers
Fixed RFID readers are readers that remain stationary rather than mobile. They’re useful when used to create a chokepoint to constantly monitor when RFID tags pass through a threshold. In addition, a fixed RFID reader comes with a port to which RFID antennas need to be attached with the use of cables. This means that each chokepoint needs to be equipped with a fixed reader and at least one antenna in order to read tags.
How Fixed RFID Readers Work
Like other RFID readers, fixed RFID readers work by utilizing radio waves to capture the information embedded in a RFID tag. The reader itself has two components—a transceiver and an antenna. The transceiver is what generates a weak radio signal that ranges anywhere between a few feet to a few yards away. This signal can activate and actually power the tag.
Fixed reader systems offer the possibility of providing very specific and complex information as long as they have the appropriate software. As an example, fixed reader chokepoints can be designed with two antennas that allow a person to know when a tag passes through a door. The readers will be able to read the tag at slightly different times, depending on when the tag was taken into or out of a room. This, in turn, allows someone to know which occurred.
