Abstract: A digital passive advertising display system and method where affiliates register to be “walking billboards”. Each affiliate can carry a display tag on their belongings such as on backpacks, or they can carry a larger display on their body. The tag or display is in radio contact with the affiliate's smartphone using a short range radio system such a BLUETOOTH™ or WiFi. A central system accepts location-based or global brand ads from advertisers and keeps track of the location of affiliates. Location-based ads based on an affiliate's location can then be pushed to his or her smartphone and hence to the display or tag. The thus affiliate displays the ad for passers-by to see. Affiliates can be compensated for carrying displays and displaying ads, and affiliates can sign up sub-affiliates.
