This idea seemed impossibly cool. Bringing mobile payment to billboards are a step ahead of the usual functions of what typical billboards do. With just a simple swipe, you can do good to the society. Its actually a pretty cool idea. Coined the ‘The Social Swipe’, it allows people to swipe their credit card through a dual screen billboard. And the best thing is, you immediately turn this into a donation with very cool story and graphics as you slide through. A bread being sliced into half, a boy getting unroped and more. Interesting use of technology.
