W.I.T.H.: Digitizing the entire cash tipping industry

I broke my hand a few years back... It was pouring rain when my cab driver pulled over. He popped open the trunk and gave me a thumbs up. I quickly realized he was politely excusing himself from stepping out to help me with my bag. Soaked, I squatted and single-handedly struggled to lift my bag over the bumper. Suddenly, I felt the bag being pulled from the other side, quickly shoved into the trunk, slamming it shut. Turns out, it was a young bellhop from the hotel next door that came dashing to the rescue. He stood drenched in his oversized trainee uniform, beaming with pride. I smiled back and thanked him, sheepishly apologizing for not having any change. He urged me not to worry. Ironically, the only person who got tipped that day was my driver. The event made me realize that perhaps we needed to shift our focus from the concept of a point of sale to what I call a point of give solution. It really made me wonder - how many other people, industries, businesses around the world are affected by the disappearance of cash? It proved to be more than I had ever imagined.
