Did they have ATM back then?

I think he only had credit cards. Back in the day you coukd only use a ATM card to pull money out, credit cards didnt have that option right away. Maybe they lost it with her luggage. Plus its a movie, you have to kind of not think about that.

I think back then a lot of people used traveler's cheques when they traveled.

Nope. As a kid we had to go to the bank drive thru to get cash. Not ATMs.

So much about your banking was tied to a signature card sitting in your local bank branch back then. There were things you couldn't do even at branches of your local bank elsewhere. Also, consider that banking was not an interstate business back then. Banks operated within state. The Cirrus network was starting around then, but even using an ATM (they did exist in 1980) at a bank that was not your own likely would not have been possible. So you're from Chicago, a big city, the liklihood of finding a branch of your bank in Arizona is slim to none. Likely there were no banks in common. The inter-bank networks were just getting started and certainly no one would know about using an ATM that way. It would actually been more out of left field than a trash-bag airbag that was in the family truckster.

I'm sure they had ATMs in the middle of the Arizona desert and the Grand Canyon. Maybe Clark could just use one at the nearest cactus or the one hole repair shop and the small town hotel. ATMs and their obnoxious expensive service charges have been around to curse us since the late seventies.

As a kid I lived on Long Island. There were no ATM's here at the time if this movie. To be honest there wasn't much here at all back then. Now it's just like Queens- yuck!

Yes they did but they were located at a bank (for after hours banking), not usually found at a hotel, gas station, etc. like they are today.

Oh, for fuck’s sake, YES, we had automated teller machines in 1983. They were external to banks in major US cities. They were not ubiquitous. Your topic asks IF we had them. We did. You do not ask how widespread they were.

You want the right answer? Ask the right question.

PS An interrogatory (question-asking) sentence ends with a “?”
not with a “.”

Yes, I am amusing myself at your expense.
