Before payment terminals, buying with a credit card was practically a workout. 😄
The embossed card was placed into a mechanical machine called a *"Knuckle Buster."*
A carbon-copy receipt was laid over the card. The cashier slid a heavy metal handle across it with the famous *"CA-CHINK!"*, imprinting the card details onto the receipt.
Then they checked a booklet of stolen card numbers.
Big purchase? Time to call the bank for an authorization code.
Today, you just tap your card. Back then... you earned the purchase! 💪😂
