In reply to Ed B.

The problem is that everyone is giving technology-based payment systems like Apple Pay way, way too much credit. If it is ever expected of people to own the device needed in order to pay, and other systems are unavailable, then we're all in trouble. There are many people today who opt for cheaper flip-phones instead of expensive smart phones with pricy data plans, and the system is not going to be available or practical all over the world. Tying payment systems exclusively to things like smart phones is a big mistake, and one that this Visa exec seems convinced will be made.
