RFID (Radio Frequency Identification) technology uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of three main components: an RFID tag, an RFID reader, and a software system.

RFID Tag: Each tag contains a microchip and an antenna. The microchip stores unique data about the item, while the antenna transmits this data to the reader.

RFID Reader: The reader emits radio waves and receives signals back from the RFID tags. Depending on the system, readers can scan multiple tags simultaneously from a distance ranging from a few centimeters to several meters.

Software System: The collected data is processed by specialized software, which interprets the information and integrates it into broader management systems for tracking and analysis.

This technology is widely used in various industries for inventory management, asset tracking, and improving operational efficiency by providing real-time visibility and reducing manual data entry errors.
