RFID (Radio Frequency Identification) is a technology that uses radio waves to automatically identify and track objects. An RFID system consists of three main components: a tag, a reader, and backend software.
Each RFID tag contains a microchip and antenna. When the tag enters the reader’s radio frequency field, it transmits stored data wirelessly. This allows multiple items to be read simultaneously, even without direct visibility.
Compared to barcodes, RFID offers higher speed, better accuracy, and greater automation. RFID tags can be embedded inside products, attached to metal, or used in harsh environments where barcodes fail.
