Where Did RFID Come From?
RFID, or Radio Frequency Identification, is a technology that uses radio waves to identify and track objects. It works with a reader that sends out a pulse, and a tag that uses this pulse to get power and send back information. Unlike barcodes, RFID tags don't need to be seen to be read, can hold more data, and many can be read at once. The technology has a long history, starting from World War II's "friend or foe" identification systems, and later developed for security in shops, access control for doors, and tracking inventory. Major developments came from government projects like tracking nuclear materials and cows, which led to its use in toll roads and supply chain management. Today, RFID is common in retail, like Uniqlo's self-checkout, and continues to be a key technology in various industries.
