Credit cards emerged in the 1950s, but the idea of buying now and paying later goes back much further
The first credit card you would recognize — a plastic card you could use at multiple stores — arrived in 1950. Diners Club issued it to 200 people in New York so they could pay for meals at restaurants without carrying cash. American Express followed in 1958 with a card aimed at business travelers. But the concept of a merchant extending credit to a customer existed for centuries before plastic showed up. Understanding where credit cards came from helps explain how they work today and why they carry both power and risk.
Key Takeaways
- Diners Club issued the first general-purpose credit card in 1950, designed for restaurant meals in New York City.
- American Express launched its card in 1958 and expanded the idea to travel, hotels, and other merchants.
- Bank of America created the first bank-issued credit card in 1958, which eventually became the Visa network.
- Credit cards replaced earlier systems like charge plates and store-only credit accounts that had existed since the early 1900s.
- The magnetic stripe, added in the 1960s, made cards faster to process and set the standard for modern credit cards.
Charge plates and store credit came first
Before plastic cards, stores issued charge plates — small metal rectangles embossed with a customer's name and account number. Department stores like Sears and Macy's used them starting in the 1920s. A customer would hand the plate to a clerk, who would press it onto a paper form to imprint the account details. The store would bill the customer monthly. These plates worked only at that one store.
Oil companies did something similar. Shell, Texaco, and other gas stations issued their own cards in the 1930s and 1940s so regular customers could fill up without paying cash. Again, each card worked only at that company's pumps. The system was convenient for the merchant — it encouraged repeat business and reduced the need to handle cash — but it locked customers into one brand.
Diners Club created the first multi-merchant card
In 1950, Diners Club founder Frank McNamara had dinner at a restaurant in New York and realized he had left his wallet at home. The embarrassment stuck with him. He imagined a card that would let him pay at multiple restaurants without carrying cash. He and his partners launched Diners Club that year with a straightforward plastic card.
The card worked like this: a restaurant would call Diners Club to verify the cardholder's account. If approved, the restaurant would write down the card number and the amount on a paper slip. At the end of the month, Diners Club would bill the cardholder. The restaurant would send the slip to Diners Club, which would pay the restaurant minus a fee — usually 7 percent. By 1951, Diners Club had 20,000 cardholders. By 1955, it had 500,000.
American Express and Bank of America expanded the model
American Express, already known for traveler's checks, saw an opportunity. In 1958, it launched its own card aimed at business travelers and affluent customers. American Express charged an annual fee — something Diners Club did not — but offered better customer service and accepted at more merchants. American Express also started issuing cards to its own employees and customers of its traveler's check business, which gave it a head start in cardholders.
The same year, Bank of America in California issued the first bank credit card. Unlike Diners Club and American Express, which were their own companies, Bank of America was a bank. It could lend money directly to cardholders and earn interest on unpaid balances. This model proved more profitable than the fee-based approach. Bank of America's card eventually became Visa. Other banks copied the model, and by the 1960s, bank credit cards were spreading across the country.
The magnetic stripe made cards faster and more find
In the 1960s, IBM developed the magnetic stripe — the dark band on the back of a credit card that stores data. Instead of writing down a card number by hand or calling to verify an account, a merchant could swipe the card through a reader. The machine would read the cardholder's information when ready. This made transactions faster and reduced errors. It also made fraud harder because the data was encoded, not just printed.
The magnetic stripe became the standard for all credit cards by the 1970s. It remained the standard for decades until chip technology and contactless payments arrived in the 2000s and 2010s. But the basic idea — a card that stores your account information and lets a merchant read it quickly — came from that one invention.
Credit cards replaced cash for everyday purchases
Through the 1960s and 1970s, credit cards remained mostly for travel, restaurants, and department stores. Most people still paid for groceries and gas with cash. But as more merchants accepted cards and more people carried them, the cards became a normal way to pay. By the 1980s, credit cards were everywhere. Supermarkets accepted them. Gas stations installed card readers at the pump. The card became the default payment method for millions of people.
This shift changed how people borrowed. With a charge plate or store credit, you had to go to that store and ask for credit. With a credit card, credit was already in your pocket. You could spend up to your limit whenever you wanted. The card made borrowing easier and faster — which was convenient, but also meant people could go into debt without thinking as carefully about it.
Modern credit cards still follow the 1950s model
The credit card you use today works almost exactly like the Diners Club card of 1950. You present a card to a merchant. The merchant verifies you have credit available. You owe the card issuer money, which you pay back monthly. The merchant pays the card issuer a fee. The card issuer makes money from interest on unpaid balances and from the fees merchants pay.
The technology has changed — chips instead of magnetic stripes, contactless instead of swiping — but the business model has not. Understanding this history matters because it shows that credit cards are a tool designed to benefit the merchant and the card issuer first, and the cardholder second. Knowing how they work and what they cost you is the only way to use them without letting them use you.
Frequently Asked Questions
Did credit cards exist before 1950?
Not in the form we know them. Charge plates and store credit accounts existed since the 1920s, but they worked only at one store or company. Diners Club in 1950 was the first card you could use at many different merchants.
Why did Bank of America's card become Visa?
Bank of America's card was called BankAmericard. In 1976, the bank spun off the card business into a separate company and renamed it Visa. Other banks that had licensed the card technology formed their own association, which also used the Visa name. Today Visa is a network that thousands of banks use to issue cards.
When did credit cards start charging interest?
From the start. Diners Club and American Express charged annual fees but no interest if you paid in full each month. Bank of America's card charged interest on unpaid balances from day one. This made bank cards more profitable and more dangerous for cardholders who carried a balance.
How did merchants verify a credit card before the magnetic stripe?
They called the card issuer by phone or looked up the card number in a printed list of stolen or invalid cards. This took time and was error-prone. The magnetic stripe made verification when ready and automatic, which is why it became standard so quickly.
