RFID readers are an integral part of any RFID tag system. Without them, it’s far more difficult to be able to determine the information contained on a RFID. Think of a RFID reader a bit like your own personal translator; it’s a way to quickly and efficiently gather information form the tags that you place on or in various items.
How RIFD Readers Work
There are many different types of RFID readers, and each of them convey information a bit differently. At their core, though, RFID readers sense RFID tags and then gather the information that they contain. They utilize radio waves to capture the information embedded in a tag. This is similar to capturing information from a barcode or label.
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. The transponder, in contrast, converts the radio frequency to usable power and also sends and receives messages. When the transponder is hit by the radio waves, it begins to deliver the information stored on it. This process only takes a few milliseconds.
With that said, each of these readers function a bit differently. Some automatically record when coming within range of a tag, while others have screens that convey more information to a user at the moment.
