What Is RFID Technology?
The radio signal recognizes a specific target and reads and writes related data, without the need to establish mechanical or optical contact between the recognition system and the specific target. The radio signal is an electromagnetic field tuned to a radio frequency to transmit data from the tag attached to the item to automatically identify and track the item. Some tags can obtain energy from the electromagnetic field emitted by the recognizer during identification, and do not require a battery; some tags have their own power source and can actively emit radio waves (electromagnetic fields adjusted to radio frequencies). The label contains information stored electronically and can be identified within a few meters. Unlike the barcode, the radio frequency tag does not need to be in the line of sight of the recognizer, and can also be embedded in the tracked object. Expansion information: Many industries have used radio frequency identification technology. By attaching the label to a
