Abstract
A vehicle having an item detection system is provided having at least one indicator for selectively emitting an alarm when activated, a vehicle alarm control module, at least one radio frequency identification (“RFID”) tag, and a radio frequency (“RF”) interrogator. The vehicle alarm control module is in communication with the at least one indicator and includes control logic for sending an activation data signal to the at least one indicator to selectively activate the at least one indicator. The RFID tag is configured for receiving a query RF signal and transmitting a reply RF signal upon receipt of the query RF signal. The RF interrogator is in communication with the vehicle alarm and is located within a specified distance of the RFID tag. The RF interrogator has a processor, and includes control logic for transmitting the query RF signal to the RFID tag.
