The Turck BL ident RFID systems contain three parts: the tag, transceiver and the interface. Tags can be active (require a battery) or passive. These tags contain internal circuitry that responds to a specific radio frequency that is provided by the transceiver. The transceiver, which is often called a reader or antenna is responsible for communicating with the tag. The interface is the means of communicating the data to a higher level data collection device such as a computer or a programmable controller. RFID in the industrial environment enables customers to improve accuracy, provide faster production speeds and minimize errors, as well as achieve substantial cost savings from both a material and labor standpoint.
