What is RFID (radio frequency identification) RFID, which stands for Radio Frequency Identification, represents a wireless communication method that harnesses electromagnetic or electrostatic coupling within the radio frequency segment of the electromagnetic spectrum. Its primary purpose is to provide a distinct means of identifying objects, animals, or individuals. How does RFID work? In every RFID setup, you've got three main parts: a scanning antenna, a transceiver, and a transponder. When you put the scanning antenna and transceiver together, they make what's called an RFID reader or interrogator. Now, there are two kinds of RFID readers - fixed ones and ones you can move around (mobile readers). The RFID reader is like a device that's connected to a network, and it can be either something you carry around or something fixed in place. It uses radio waves to send signals that wake up the RFID tag. Once the tag wakes up, it sends a signal back to the antenna, and this sig
