Dee Hock, the visionary founder of Visa Inc. who built a system for modern electronic payments infrastructure that transformed how money changes hands, died this weekend at 93.

While Hock’s name may not be well-known, his impact is felt by anyone who has made or received a card payment. Modern shoppers take for granted the nearly instantaneous speed of card payments online or at a store counter, but reaching that point required vast technological innovation as well as unprecedented coordination between rival banks.
