I remember using Barclays ATMs in Sheffield in the mid 70s.
There were no plastic cards; you had to get the bank to post you a pack of five punched cards, each of which could be used to draw the princely sum of £10.
There was a re-ordering slip in the envelope with those punched cards, which you could post back to the bank when you needed some more punched cards. In practice that often meant posting the reordering slip back as soon as you got it, so as to be sure of not running out of punched cards.
