Abstract:
A system comprising two or more cards, at least one being a sensor card, and at least one being a response card, provide interactivity features for traditional print-type advertising content. The sensor card senses an environmental variable, such as the presence of a person, then wirelessly communicates to a proximately located response card, which initiates an activity based on the received wireless communication.
