I can ELIMINATE credit card reciept paper. It is estimated that there are 864 million card transactions every day around the world.
I have the concept with a product in development to completely eliminate all receipt paper. ~10,000 payment card transactions every second around the world. If 1/2 of those transactions included receipt paper the average cash spent on receipt paper per second around the world is $50. The average per day then would be ~$6 million dollars. Imagine eliminating one of the biggest expenses for every retail business.
