Today in 1969, Chemical Bank installed the first ATM in the U.S. at its branch in Rockville Centre, New York. The first ATMs were designed to dispense a fixed amount of cash when a user inserted a specially coded card. A Chemical Bank advertisement boasted “On Sept. 2 our bank will open at 9:00 and never close again.” Today, there are more than 2.1 million ATMs installed worldwide. And tomorrow? The mobile payment market will reach $670 billion in 2015, according to Jupiter Research.
