Credit cards emerged in the 1950s, starting with Diners Club in 1950

The first credit card you could use at multiple merchants was Diners Club, launched in February 1950. It was created by Frank McNamara and Ralph Schneider, who wanted a way to pay for restaurant meals without carrying cash. The card worked at 27 restaurants in New York City at launch. Within a year, Diners Club had expanded to 10,000 cardholders and 1,000 merchants.

Before Diners Club, stores and gas stations issued their own cards that worked only at that single business. A shopper might carry five or ten different cards, each one usable at one place only. Diners Club changed this by creating a card that worked across many restaurants, hotels, and shops. The cardholder paid Diners Club monthly, and Diners Club paid the merchants.

Diners Club charged an annual fee and took a percentage of each purchase from the merchant. This model — the cardholder pays a fee, the merchant pays a percentage — became the standard that credit card companies still use today.

Key Takeaways

  • Diners Club, founded in 1950, was the first credit card that worked at multiple merchants rather than just one store or gas station.
  • Before credit cards, consumers either carried cash or used single-merchant cards issued by individual businesses.
  • American Express entered the market in 1958 and became the largest travel and entertainment card company.
  • Bank-issued credit cards like Visa and Mastercard arrived in the 1960s and made credit cards available to far more people than travel cards did.
  • The technology behind credit cards has changed from imprinting machines to magnetic strips to chip readers, but the basic business model has remained the same since 1950.

American Express and the rise of the travel card

American Express launched its credit card in 1958, eight years after Diners Club. Unlike Diners Club, which focused on restaurants and hotels, American Express positioned itself as a card for business travelers and affluent consumers. American Express charged higher annual fees but offered more prestige and broader acceptance.

American Express and Diners Club were called travel and entertainment cards because they were designed for people who traveled for business or leisure. Both required the full balance to be paid each month — you could not carry a balance from one month to the next. This made them different from the credit cards that came later, which allowed you to pay over time and carry a balance.

Travel cards remained exclusive and expensive. They were not available to most people. A cardholder needed a steady income and a good reputation to get one. This changed when banks entered the market.

Bank credit cards: Visa and Mastercard in the 1960s

The first bank-issued credit card was the BankAmericard, launched by Bank of America in California in 1958. It was the first card that let cardholders carry a balance and pay interest on what they owed. This was revolutionary. Instead of paying the full bill each month, you could pay a minimum amount and owe interest on the rest.

BankAmericard expanded nationally and was renamed Visa in 1976. Around the same time, a group of banks created Mastercard (originally called Interbank Card) to compete. Visa and Mastercard were not owned by a single company the way Diners Club and American Express were. Instead, they were networks that many different banks could join. A bank would issue the card to its customers, and Visa or Mastercard would handle the transactions.

This network model made credit cards available to millions of people who could never have gotten a Diners Club or American Express card. You did not need to be wealthy or a frequent traveler. You just needed a bank account and a decent credit history.

How credit card technology has changed since 1950

The earliest credit cards were made of cardboard or thin plastic and had no security features. Merchants wrote down the card number by hand or used a mechanical imprinting machine that pressed the card number onto a paper receipt. There was no way to verify that the card was real or that the person using it was the cardholder.

In the 1960s and 1970s, cards began to include a magnetic stripe on the back. This stripe held the cardholder's account number and other information. A merchant could swipe the card through a reader to pull up the account information instantly. This made transactions faster and reduced fraud because the merchant could verify the card was real.

In the 2000s, cards began to include a chip (also called an EMV chip) embedded in the front. The chip is more secure than a magnetic stripe because it creates a unique code for each transaction. A criminal who steals a card number cannot use it without the physical card and the chip. Today, most cards have both a chip and a magnetic stripe for backward compatibility.

The latest development is contactless payment, where you tap or wave the card near a reader instead of inserting it or swiping it. This technology has been available since the 2000s but became widespread during the COVID-19 pandemic when merchants wanted to reduce physical contact.

Why credit cards took off in the 1960s and 1970s

Credit cards grew rapidly once banks started issuing them because they solved a real problem: carrying large amounts of cash was inconvenient and unsafe. A credit card was lighter, easier to replace if lost, and offered a record of purchases. Merchants liked them because they reduced the risk of bad checks and counterfeit cash.

The ability to carry a balance — to pay over time — also made credit cards attractive to consumers. You could make a large purchase and pay for it gradually instead of saving up the full amount first. This made credit cards a form of short-term borrowing.

By the 1980s, credit cards had become mainstream in the United States. Most adults had at least one card. Today, credit cards are the most common form of payment for in-person and online purchases in the U.S., though debit cards and digital payment apps have grown significantly in recent years.

The difference between early credit cards and today's cards

The basic structure of a credit card has not changed much since 1950: you borrow money from the card issuer, you use the card to make purchases, and you pay back what you borrowed plus interest. But the details have changed significantly.

Early credit cards charged a flat annual fee and a simple interest rate. Today's cards often have no annual fee but offer rewards — cash back, airline miles, or points — that vary depending on what you buy. Some cards charge different interest rates depending on your credit score. Some offer a 0% introductory rate for a limited time.

Early cards were issued only by banks or large companies like American Express. Today, retailers, airlines, and other businesses issue their own branded credit cards in partnership with a bank or payment network. A store card might offer discounts when you shop there, or an airline card might give you free checked bags.

The biggest change is in how widely available credit cards are. In 1950, you had to be wealthy or well-connected to get one. Today, credit card offers arrive in the mail and email constantly, and many people have multiple cards. This has made credit more accessible but also more risky — it is easier to overspend and carry debt.

Frequently Asked Questions

Did credit cards exist before 1950?

Single-merchant cards existed before 1950. Gas stations and department stores issued their own cards that worked only at that business. But Diners Club in 1950 was the first card that worked at multiple merchants across different industries. That is what made it the first true credit card.

Why did it take so long for credit cards to become popular?

Early credit cards were expensive to use and only available to wealthy people. The real breakthrough came in the 1960s when banks started issuing cards and letting people carry a balance. Once credit cards became accessible to ordinary people, they spread quickly.

Are credit cards safer now than they were in the 1950s?

Yes. Early cards had no security features — a criminal who found your card number could use it. Modern cards have chips that create a unique code for each transaction, making them much harder to counterfeit. Contactless payment and digital wallets add another layer of security.

What happened to Diners Club?

Diners Club still exists but is much smaller than Visa, Mastercard, and American Express. It is now owned by Discover Financial Services. Most people today use Visa or Mastercard because they are accepted almost everywhere, while Diners Club is accepted at fewer merchants.

How did credit cards change the way people spend money?

Credit cards made it possible to spend money you did not have yet. Before credit cards, most people saved up before making a large purchase or used installment plans from the merchant. Credit cards made borrowing easier and faster, which increased consumer spending but also increased personal debt.
