Abstract
The present disclosure includes a system that provides visual and electronic information in a readily identifiable system. For example, the present disclosure is directed to a combination tag, suitable for use as a vehicle identification window sticker. The combination tag includes a retroreflective article having an optical surface and a radio frequency responsive element. The radio frequency-responsive element includes an antenna and an integrated circuit. The radio frequency-responsive element has information storage and transmission capabilities adapted to enable an interrogation system to obtain information from the radio frequency-responsive element. The radio frequency-responsive element is operably coupled to the retroreflective article.
