PROBLEM BACKGROUNDBusiness cards are today’sperson-to-person marketing tool

GDA Digital MediaGDA Digital Media is seeking a newway of accepting business cards

The idea is to build a creative machinecreative machine that willhighlight GDA’s receptive and “down-to-earth”approach to business.

“To design, build, and evaluate an innovative, multi-step machine that accepts business card and places it randomly in a defined area of the wall.”
