Pull a credit card from your wallet today and you will probably see a sleek piece of plastic or metal with a chip, contactless technology and perhaps a rewards logo. The first widely recognized general-purpose payment card looked far less impressive. It was essentially a cardboard membership card designed to help customers pay restaurant bills without carrying cash.
Diners Club introduced that breakthrough in 1950, decades before tap-to-pay, online shopping and digital wallets became routine. Yet the story of that early card reveals more than a curious piece of financial history. It shows how a simple payment convenience gradually became a massive borrowing system, complete with revolving balances, interest charges, rewards programs and a global payment infrastructure.
