What are RFID tags, and how do they work?

RFID tags are electronic chips that emit radiosignals. Tags can be active or passive. Oftenan RFID tag contains only a unique identifieralthough some may contain more information.Different tags transmit at a distance that maybe limited to a fraction of an inch or extend to1,500 feet. The system with which a tag communicatesoften creates and stores informationabout where a tag is, what time it passes areader and may relate that information to a purchaseor the movement of materials or people.

RFID

Who is using it?– Walmart – EZ Pass and SmartTag for toll roads– Exxon Speedpass– New car security systems– Agriculture– Libraries– Records Management

How does it work?

• A tag is affixed to a resource.

• The tag is programmed to be recognized by the system.

• The tag can be scanned by a reader device to help manage the collection of resources.

Types of Tags

PassiveNo imbedded power source. Weaker signal.

Active Imbedded power source. Stronger signal.
