When you paid for something with a credit card, the clerk would put it into a little gadget, then place a credit card form on top. A roller would move over it, causing the embossing on your card to imprint on the form.
Plus, they’d check your credit card number in a little book. If your number was listed in the book, your card was declined. Imagine… you could steal a card, and use it for at least a week or so before the book was printed up and distributed to merchants across the country. See how the communications revolution changed the world?
