Credit cards went mainstream in the 1950s and 1960s, when banks started issuing them widely instead of just department stores

Credit cards existed before the 1950s, but they were specialty items — a department store would issue one to a trusted customer, and it worked only at that store. The real shift happened after World War II, when banks realized they could make money by issuing cards that worked at multiple merchants. Diners Club launched in 1950 as the first card accepted at restaurants and other businesses across a network. American Express followed in 1958. But the moment credit cards became truly popular was when Bank of America started mailing Visa cards (then called BankAmericard) to customers in California in 1958, and other banks copied the model nationwide through the 1960s.

Before that shift, most people bought things on layaway, paid cash, or used store credit that the store itself managed. A bank-issued card that worked everywhere was genuinely new. By the late 1960s, credit cards were common enough that people carried them regularly. By the 1970s, they were standard.

Key Takeaways

  • Department stores issued single-store credit cards starting in the early 1900s, but these only worked at that one store.
  • Diners Club (1950) and American Express (1958) created the first multi-merchant card networks, but they were expensive and aimed at business travelers and wealthy customers.
  • Bank of America's BankAmericard, mailed to California customers in 1958 and rolled out nationally through the 1960s, made credit cards accessible to ordinary people.
  • By the 1970s, bank-issued credit cards were standard, and the modern credit card system was in place.

Why department stores issued the first credit cards

Department stores created their own credit system in the early 1900s because it kept customers coming back and increased sales. A store would issue a card (really just a record in a ledger) to a customer with a good reputation, and that customer could buy now and pay later. The store tracked the balance, sent a bill at the end of the month, and collected payment. This was profitable for the store because customers spent more when they could defer payment, and the store charged interest on the balance.

The catch was that the card only worked at that store. If you had a Macy's card, you could not use it at Gimbels. You needed a separate card for each store where you wanted credit. By the 1940s, many people carried a stack of store cards in their wallets.

How Diners Club and American Express changed the model

Diners Club, founded in 1950, introduced the idea of a card that worked at multiple merchants. The founder, Frank McNamara, realized that restaurants and hotels could benefit from a payment system that let customers pay after the meal instead of carrying cash. Diners Club issued cards to members, signed up restaurants and hotels to accept them, and took a percentage of each transaction. The cardholder paid the full balance each month — there was no revolving credit, no interest charges.

American Express entered the market in 1958 with a similar model: a card accepted at many merchants, full payment due monthly, and a fee to join. Both cards were expensive (membership cost real money) and aimed at business travelers and affluent customers. They were not for everyday people buying groceries or gas.

Why Bank of America's BankAmericard became the turning point

Bank of America saw an opportunity that Diners Club and American Express had missed: ordinary people wanted credit too, and banks could profit by issuing cards directly to their customers. In 1958, Bank of America began mailing BankAmericard cards to customers in California without asking first. The card worked at thousands of merchants, and cardholders could carry a balance and pay interest on it — the bank made money both from the merchants (a small percentage of each sale) and from the interest customers paid.

This was revolutionary because it made credit accessible to people who were not wealthy or frequent travelers. You did not need to be approved in advance or pay a membership fee. If you had a bank account, you could get a card in the mail. Other banks copied the model, and by the mid-1960s, bank-issued credit cards were spreading across the country.

The BankAmericard eventually became Visa, which still operates today. The system Bank of America created — a bank issues the card, merchants pay a fee to accept it, cardholders pay interest on balances — is the same system that runs most credit cards now.

How credit cards replaced cash and store credit in everyday life

Through the 1960s and 1970s, credit cards gradually became normal. Merchants started accepting them because customers wanted to use them and because the merchant fee was lower than the cost of managing their own credit system. Customers carried cards because they were convenient — no need to carry large amounts of cash or manage multiple store accounts. By the 1980s, credit cards were the default way most people bought things on credit.

The shift was not when ready. Older people and rural areas held onto cash and store credit longer. But by the 1990s, credit cards were so standard that not having one put you at a disadvantage — you could not rent a car, book a hotel, or order online without one. The technology changed too: cards went from imprints on paper to magnetic strips to chip readers to contactless payments, but the underlying system remained the same.

What made credit cards popular with merchants

Merchants accepted credit cards because they solved a real problem: managing customer credit was expensive and risky. A store had to decide who to extend credit to, track balances, send bills, and chase down people who did not pay. Credit card companies took on that risk and that work. The merchant paid a fee (typically 2 to 5 percent of the sale) but got paid when ready and did not have to worry about collection.

For the customer, the appeal was simpler: you could buy something without having cash on hand, and you had time to pay. For the bank issuing the card, the appeal was profit: the merchant fee plus the interest on the balance. All three parties benefited, which is why the system spread so quickly once it started.

The role of technology in making credit cards practical

Early credit cards were impractical by modern standards. The merchant had to write down the card number, the customer's name, and the amount by hand, then send the paperwork to the bank. This was slow and error-prone. The real breakthrough came in the 1960s with the magnetic stripe, which let merchants swipe the card and read the information electronically. This made transactions faster and reduced fraud.

Later innovations — the chip, the PIN, online authorization — made credit cards even more find and convenient. But the basic system was already in place by the 1970s. Technology made it faster and safer, but it did not change the fundamental idea: a bank issues a card, the cardholder uses it to buy things, and the bank collects payment later.

Frequently Asked Questions

Did credit cards exist before the 1950s?

Yes, but only as single-store cards issued by department stores starting in the early 1900s. Diners Club (1950) and American Express (1958) created the first multi-merchant cards, but they were expensive and aimed at wealthy customers. Bank-issued cards that ordinary people could get came later.

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

The technology and infrastructure did not exist until the 1950s and 1960s. Before that, tracking balances and processing payments required paper and manual work. Banks also had to build a network of merchants willing to accept the cards. Once the system was in place, adoption was relatively fast.

When did credit cards become more popular than cash?

Credit cards became the default payment method for many transactions by the 1990s, but cash remained common for small purchases. Today, debit cards and digital payments have reduced cash use further, but credit cards have been the standard way to buy on credit since the 1980s.

How did credit card companies convince merchants to accept them?

Merchants accepted cards because they eliminated the cost and risk of managing their own credit system. The merchant fee (2 to 5 percent of the sale) was cheaper than handling collections and bad debt. Customers wanted to use cards, so merchants had to accept them to stay competitive.

What was the biggest difference between early credit cards and modern ones?

Early cards required manual processing — the merchant wrote down the information and sent it to the bank. Modern cards are processed when ready, electronically, and with fraud protection built in. The basic idea is the same, but the speed and security are vastly different.
