An advertising compliance monitoring system is provided that includes a
tag affixed to a sign or marketing material or shopper ID card, the tag
communicating with a reader on a periodic basis. The tag includes a
memory for storing tag data, a transmitter and a receiver. The tag uses
sleep modes to conserve power. The tag transmits tag data to a reader in
response to an interrogation request, or automatically on a periodic
basis. The tag data includes an identification number used to identify
the tag associated with a particular sign, price, marketing material or
shopper, status data (e.g., delivered, displayed), and time and date
information. This data is processed by a central server to determine
compliance with and/or exposure to a particular advertising program.
