DRM Labs has developed Voupon iTV, an interactive system that lets TV watchers use and redeem coupons by using TV remote control. "When a consumer is watching an interactive commercial that offers a percent or dollar off discount Voupon for a specific product at a specific retailer, the consumer can accept the Voupon by using their remote. The Voupon gets attached to the consumer's registered credit card or inputs their credit card information at the time."
