The first credit card was the Diners Club card, issued in 1950
The Diners Club card arrived in February 1950 and is widely recognized as the first true credit card. It was created by Frank McNamara and Ralph Schneider, who wanted a way to pay for restaurant meals without carrying cash. The card worked by letting cardholders charge meals at participating restaurants, then receive a monthly bill to pay in full.
Diners Club cards were made of cardboard at first, not plastic. The company charged an annual membership fee and took a percentage from restaurants that accepted the card. By the end of 1950, Diners Club had signed up about 20,000 members and 1,000 restaurants in New York City alone.
What made Diners Club different from earlier payment methods was that it created a network — a cardholder could use the same card at many different merchants, rather than having a separate account at each store. This network model became the foundation for how credit cards work today.

Bank of America's BankAmericard changed how credit worked in 1958
In 1958, Bank of America introduced the BankAmericard in California. Unlike Diners Club, which required you to pay your full balance each month, BankAmericard let you carry a balance and pay interest on what you owed. This revolving credit model meant you could borrow money from the bank itself, not just defer payment to a merchant.
BankAmericard was also the first credit card issued by a bank to its own customers. This made it more widely available than Diners Club, which had been limited to a membership program. Bank of America mailed unsolicited cards to thousands of customers in California, a practice that would later be restricted by law but that helped the card spread quickly.
The card was so successful that Bank of America licensed it to other banks across the country. In 1976, the BankAmericard was renamed Visa, and it became the largest credit card network in the world.
Mastercard launched in 1966 to compete with Visa
By the mid-1960s, Visa (still called BankAmericard) was growing rapidly, but other banks wanted their own credit card network. In 1966, a group of banks created Mastercard, originally called the Interbank Card. Mastercard used the same revolving credit model as Visa and competed directly for cardholders and merchant acceptance.
The rivalry between Visa and Mastercard drove innovation in the credit card industry. Both networks invested in technology, expanded internationally, and added new features to attract customers. Today, Visa and Mastercard remain the two largest credit card networks in the United States.
Other card networks emerged later, including American Express (which started as a travel and entertainment card in 1958) and Discover (which launched in 1986), but Visa and Mastercard have maintained their dominant position.
Credit cards moved from cardboard to plastic in the 1950s
The earliest Diners Club cards were made of cardboard, which was cheap to produce but wore out quickly and could not hold much information. By the mid-1950s, credit card companies switched to plastic, which was more durable and could be embossed with the cardholder's name and account number.
Embossing meant that a merchant could place the card in a mechanical imprinter, lay a paper receipt on top, and press down to transfer the card's details onto the receipt. This process was slow but did not require electricity or a phone line, so it worked in any store.
The next major shift came in the 1960s, when credit card companies added a magnetic stripe to the back of cards. The magnetic stripe stored the cardholder's account information in a format that machines could read electronically. This made transactions faster and reduced errors from manual imprinting.
American Express created a different model for charge cards
American Express issued its first charge card in 1958, the same year Bank of America launched BankAmericard. However, American Express cards worked differently — they required cardholders to pay the full balance each month, like Diners Club. American Express called these "charge cards" rather than "credit cards" because they did not offer revolving credit.
American Express positioned itself as a premium card for business travelers and wealthy individuals. The company charged higher annual fees than Visa or Mastercard but offered better customer service and travel benefits. Over time, American Express introduced some cards that allowed you to carry a balance, blurring the line between charge cards and credit cards.
Today, American Express is the third-largest card network in the United States, though it remains smaller than Visa and Mastercard.
The shift to online and contactless payments began in the 1990s
For decades, credit cards were used primarily in person — you handed the card to a merchant, they swiped it or imprinted it, and you signed a receipt. In the 1990s, the internet created a new way to use credit cards: entering your card number on a website to make a purchase.
Online transactions required new security measures because the cardholder was not present and could not sign a receipt. Card networks developed encryption technology and fraud detection systems to protect against unauthorized use. By the early 2000s, online shopping had become mainstream, and credit cards were the primary payment method.
In the 2010s, contactless payments emerged — you could hold your card near a reader without swiping or inserting it, and the transaction would complete in seconds. Mobile wallets like Apple Pay and Google Pay let you store your credit card information on your phone and pay by tapping the phone instead of the card itself.
Credit card regulation has changed significantly since 1950
In the early days of credit cards, there were few rules. Banks could charge whatever interest rates they wanted, impose unlimited fees, and change terms whenever they chose. Cardholders had little protection against fraud or billing errors.
The Truth in Lending Act of 1968 required card issuers to disclose interest rates and fees clearly, so cardholders could compare offers. The Fair Credit Billing Act of 1974 gave cardholders the right to dispute charges and required banks to investigate billing errors. The Credit Card Accountability, Responsibility, and Disclosure Act (CARD Act) of 2009 added more protections, including limits on interest rate increases and restrictions on fees.
These laws made credit cards safer and more transparent, but the basic model — borrowing money from a bank and paying interest on the balance — has remained the same since BankAmericard introduced it in 1958.
Frequently Asked Questions
Did credit cards exist before 1950?
Some stores and oil companies issued their own cards in the 1920s and 1930s, but these were not true credit cards — they were accounts you could use only at that specific company. Diners Club was the first card that worked as a network across many different merchants.
Why did Bank of America mail unsolicited credit cards to customers?
In the 1950s and 1960s, there were no laws against mailing credit cards to people who had not requested them. Bank of America used this tactic to sign up customers quickly. Congress later passed laws restricting unsolicited card mailings because of fraud and identity theft concerns.
When did credit cards become safer to use online?
Online credit card security improved gradually through the 1990s and 2000s. Encryption technology, fraud detection systems, and the development of find payment gateways made online shopping safer. Today, online transactions are often safer than in-person transactions because of advanced fraud monitoring.
Are credit cards still the main way people pay for things?
Credit cards remain widely used, but their share of payments has declined as debit cards, mobile wallets, and other payment methods have grown. However, credit cards are still the dominant way Americans borrow money for purchases.
What happened to Diners Club?
Diners Club is still in operation but is much smaller than Visa, Mastercard, or American Express. It is now owned by Discover Financial Services and is accepted at fewer merchants than the major card networks.
