The founders of ViVOtech are vocal proponents of the value proposition for contactless payments. They have staked their company’s future on it. But from their participation in a number of high-profile mobile payment trials they found that the typical value proposition had a weak spot. Full service restaurants with table service didn’t like the idea of contactless payments–because they did not want their staff to take possession of a diner’s keys or cell phone to initiate a contactless payment back at the point of sale (POS) device. And you can bet the diner wouldn’t like this either.
