How Does an RFID Tag Work? Understanding RFID Tag Communication and Identification Technology
Understanding the Basic Working Principle of an RFID Tag From years of working with RFID deployment projects, I have found that the most common misunderstanding is treating an RFID tag as a simple “wireless barcode.” It is not. An RFID tag is a miniature electronic identification device containing an antenna and an integrated circuit (IC) that communicates through radio waves. At Cykeo, our RFID engineers have tested tags and readers in environments ranging from European manufacturing workshops to warehouse corridors where metal interference, dense inventory, and moving vehicles affect reading performance. The difference between a laboratory test and a real deployment often comes down to antenna design, frequency selection, tag orientation, and reader configuration. An RFID system usually contains three essential components: Component Function RFID Tag Stores identification data and communicates with readers RFID Reader Sends radio frequency signals and receives tag responses S...
