This document outlines a system and device for detecting incorrect or absent information related to legal operation of a motor vehicle. Information is periodically gathered by an in-vehicle system capable of reading RFID-tagged documents (such as registration and insurance) and vehicle features (such as license plate and vehicle identification number). Radio-frequency transmission of the information (or an abbreviated version thereof) is performed on receipt of a valid RF activation signal from a portable or fixed-location extra-vehicle reading system. Upon receipt of the information, the extra-vehicle reading system ensures that no discrepancy in on-vehicle information is present by performing a local check and consulting an authoritative database. If a discrepancy is encountered, information is missing, or the authoritative database entry is flagged, law-enforcement officials are notified. The system may also be used for detection of moving infractions such as speeding and red light violations and logging of vehicle locations for security purposes.
