The Full Form of RFID: Radio-Frequency IDentification

RFID stands for Radio-Frequency IDentification. RFID is a way to use radio waves to identify and track things. It’s like giving things a special radio sticker that can talk to a computer without needing to touch or see it. RFID works like a digital barcode using radio waves. An RFID tag, like a smart sticker, holds information that a reader can “talk” to wirelessly, identifying objects and making tasks easier.

RFID technology is used in things like key cards for entering buildings, tracking packages in warehouses, and even in some credit cards for quick payments. It helps computers know where things are without having to physically touch them.
