    Radio Frequency Identification (RFID) is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information that can be read from several meters away without requiring direct line-of-sight12.

    How RFID Works

    RFID systems consist of three main components: a scanning antenna, a transceiver, and a transponder (the RFID tag). The scanning antenna and transceiver are often combined into a single device called an RFID reader or interrogator. The reader sends out radio waves that activate the RFID tag, which then sends back data to the reader12.

    There are two main types of RFID tags:
