WHAT IS ISDD? IDDI has entered into an alliance with leading retail stores to provide advertisers with an ISDD (or in-store digital display) system that delivers specific messages for target audience at point-of-purchase. It is an I.T.-based infrastructure that allows advertisers to communicate to consumers in a manner that is, efficient, timely, creative, and cost effective. Digital content is managed centrally and uploaded through the internet to provide clients with up to date messages aimed towards a wide range of consumers inside retail stores across the Philippines.
