radiofrequency identification (RFID)

Radiofrequency Identification (RFID) is a technology that uses radio waves to automatically identify and track objects or individuals. It involves a small electronic tag, called an RFID tag or chip, attached to an item, and a reader device that emits radio signals. When the reader's signals reach the tag, it responds with stored information, such as a unique ID. This system allows for quick and contactless identification, commonly used in inventory management, access control, and supply chains, improving efficiency and accuracy without the need for direct line-of-sight scanning like barcodes.
