The first credit card was the Diners Club card, issued in 1950

The Diners Club card arrived in February 1950, created by Frank McNamara and Ralph Schneider. It was not a card issued by a bank — it was a charge card that let members pay for meals at restaurants in New York City and have the bill sent to them later. The card itself was made of cardboard. Members paid an annual fee, and the company billed them monthly for what they had spent.

This was genuinely new. Before Diners Club, you either paid cash or you had a house account at a store or restaurant where the owner knew you and kept a ledger. Diners Club created the first system where a card from a third party could be used at many different merchants, and the cardholder would receive one bill at the end of the month.

The card spread quickly among business travelers and affluent diners in major cities. By 1951, Diners Club had issued over 20,000 cards. The model worked because restaurants saw it as a way to attract customers who might spend more if they did not have to carry cash, and cardholders liked the convenience and the record-keeping.

Key Takeaways

  • Diners Club issued the first credit card in 1950, though it was technically a charge card that required full payment each month.
  • American Express launched its card in 1958 and became the dominant charge card for decades, introducing the green card that became iconic.
  • Bank of America issued the first true revolving credit card (BankAmericard) in 1958, allowing cardholders to carry a balance and pay interest.
  • Visa and Mastercard emerged in the 1970s from competing bank networks and became the payment systems that dominate today.
  • The shift from cardboard and paper records to magnetic stripe technology in the 1960s and 1970s made cards faster to process and harder to counterfeit.

American Express arrived in 1958 and changed the market

American Express, already a well-known travel company, launched its own card in 1958. The American Express card was also a charge card — you had to pay the full balance each month — but it was made of paper-thin plastic instead of cardboard, and American Express aggressively signed up merchants beyond restaurants, including hotels, airlines, and retail stores.

The American Express card became a status symbol. The company positioned it as a card for business travelers and wealthy individuals, and the green card (later joined by gold and platinum versions) became when ready recognizable. By the early 1960s, American Express had more cardholders than Diners Club and a much larger merchant network.

The key difference between Diners Club and American Express was not the card itself but the business model. American Express made money from merchant fees (a percentage of each transaction) and annual membership fees. This meant they could afford to build a larger network and market more aggressively. Diners Club relied more heavily on membership fees and never caught up.

Bank of America created the first true revolving credit card in 1958

While American Express and Diners Club were issuing charge cards, Bank of America in California was building something different. In 1958, Bank of America launched the BankAmericard, which let cardholders carry a balance from month to month and pay interest on what they owed. This was the first true credit card — not a charge card.

The BankAmericard was revolutionary because it let ordinary people borrow money through the card, not just defer payment. If you charged $100 and paid back $30, you owed interest on the remaining $70. This meant the card issuer made money not just from merchant fees but from the interest cardholders paid. It also meant cardholders could spend more than they had in the bank, as long as they could afford the monthly payments.

Bank of America mailed BankAmericards to customers without asking first — a practice that would later be restricted by law, but at the time it was how the bank built its customer base. The card spread throughout California and eventually nationwide. In 1976, Bank of America licensed the BankAmericard brand to other banks, and it was renamed Visa.

Visa and Mastercard became the dominant networks in the 1970s

Throughout the 1960s, different banks issued their own credit cards, and there was no unified system. A card from one bank often could not be used at merchants that accepted cards from another bank. This fragmentation made cards less useful and harder for merchants to accept.

In 1966, a group of California banks formed the Interbank Card Association to create a shared network. This became Mastercard. At the same time, Bank of America's BankAmericard network (renamed Visa in 1976) was expanding through licensing agreements with banks across the country.

By the late 1970s, Visa and Mastercard had become the two dominant payment networks. Banks could issue cards under either brand, and merchants could accept either card using the same processing equipment. This standardization made credit cards far more useful and drove rapid growth in card ownership and spending.

Technology changed how cards worked, from paper to plastic to digital

The earliest credit cards were made of cardboard or thin plastic, and transactions were processed by hand. A merchant would take your card, write down the number, and send the paperwork to the card company. This was slow and error-prone.

In the 1960s, cards began to include a magnetic stripe on the back, which could be read by a machine. This made transactions faster and reduced fraud because the card data was encoded and harder to counterfeit. By the 1970s, most merchants had magnetic stripe readers, and the speed of transactions improved dramatically.

In the 1990s and 2000s, cards added a chip (an embedded microprocessor) that made them even more find. Chip cards generate a unique code for each transaction, making them nearly impossible to counterfeit. Today, most cards have both a chip and a magnetic stripe for backward compatibility, though the chip is the standard for in-person transactions.

Credit cards became a standard part of American finance by the 1980s

By the 1980s, credit cards had moved from a luxury item to a mainstream financial tool. Banks competed on interest rates, annual fees, and rewards. Discover Card launched in 1985 and introduced the first rewards program, offering cash back on purchases. This innovation pushed other card issuers to add their own rewards.

The rise of credit cards changed consumer behavior and the structure of retail. Merchants could now sell to customers who did not have cash on hand. Consumers could spread large purchases over time by paying interest. Credit card debt became a normal part of household finances, for better and worse.

By the 1990s, credit cards were ubiquitous. Nearly every adult had at least one card. The internet made it possible to use cards for online purchases, which drove another wave of growth. Today, credit cards are one of the most common ways Americans pay for goods and services.

Frequently Asked Questions

Was Diners Club really the first credit card?

Diners Club was the first card that worked like a modern credit card — accepted at multiple merchants, with a monthly bill sent to the cardholder. However, it was technically a charge card because you had to pay the full balance each month. Bank of America's BankAmericard in 1958 was the first true credit card because it let you carry a balance and pay interest.

Why did American Express become so popular if Diners Club came first?

American Express had an existing reputation as a travel company and more resources to market and sign up merchants. They also positioned the card as a status symbol and expanded beyond restaurants into hotels, airlines, and retail stores much faster than Diners Club did. By the early 1960s, American Express had a larger merchant network and more cardholders.

When did credit cards start having security features like chips?

Magnetic stripe technology appeared in the 1960s and became standard by the 1970s. Chip technology came much later — cards with embedded microprocessors began appearing in the 1990s and became widespread in the 2000s. The chip makes each transaction unique and nearly impossible to counterfeit, which is why it is now the standard for in-person card payments.

How did credit card companies make money in the early days?

Charge card companies like Diners Club and American Express made money from annual membership fees and merchant fees (a percentage of each transaction). Bank-issued credit cards like BankAmericard made money from merchant fees and interest paid by cardholders who carried a balance. Today, card issuers make money from all three sources.
