The first ATMs were designed to dispense a fixed amount of cash when a user inserted a specially coded card.[13] A Chemical Bank advertisement boasted "On Sept. 2 our bank will open at 9:00 and never close again."[14] Chemical's ATM, initially known as a Docuteller was designed by Donald Wetzel and his company Docutel. Chemical executives were initially hesitant about the electronic banking transition given the high cost of the early machines. Additionally, executives were concerned that customers would resist having machines handling their money.[15] In 1995, the Smithsonian National Museum of American History recognised Docutel and Wetzel as the inventors of the networked ATM.
