Radio-frequency Identification Systems
Radio-frequency Identification (RFID) systems use electromagnetic fields to automatically identify and track tags attached to objects. An RFID tag contains a microchip with stored data and an antenna. When a reader emits radio waves, the tag responds by sending its information back to the reader. This technology is widely used for inventory management, ticketing, access control, and even in pets’ microchips. RFID offers advantages such as speed and accuracy in tracking items without direct line-of-sight, making processes more efficient in various industries.
