The older bank buildings put the ATMs in the vestibule for customer safety. You had to swipe your atm card at the entrance to buzz the door in order to get access to the ATM machine. It was an attempt at security for the customers.
But it didn’t take long for people to realize that you could use anything with a magnetic strip to buzz the door.
