The first credit card was issued in 1950
The Diners Club Card, launched in February 1950, 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.
Before Diners Club, businesses issued their own charge plates — metal or cardboard tokens that customers could use to buy on credit at that specific store. Department stores like Sears and Macy's had used charge plates since the 1920s. But these were not credit cards in the modern sense because they only worked at one company and required payment in full each month.
What made Diners Club different was that it worked at multiple restaurants across different cities, and it was issued by a third party rather than by the merchant. This model — a card issued by a financial company that works at many locations — became the template for all credit cards that followed.
Key Takeaways
- Diners Club issued the first credit card in 1950, allowing customers to charge meals at multiple restaurants and pay one monthly bill.
- Before credit cards, charge plates issued by individual stores let customers buy on credit only at that store.
- Bank of America launched the BankAmericard in 1958, which became Visa and introduced the revolving credit model where you could carry a balance month to month.
- MasterCard (originally Interbank Card) launched in 1966 and competed directly with Visa for market share.
- The magnetic stripe, introduced in the 1960s, made credit cards faster and more find than earlier embossed metal designs.
How charge plates led to the first credit cards
Charge plates were metal or cardboard rectangles embossed with a customer's name and account number. When you made a purchase, the merchant would place the plate in a manual imprinter, press down, and create a carbon copy of your account details on the sales slip. You would sign the slip, and the store would bill you later.
The system worked well for individual stores, but it had a major limitation: each store issued its own plate, so you needed a separate one for every merchant. By the 1940s, some customers carried dozens of charge plates. A businessman might have one for his department store, one for his gas station, one for his hotel, and so on.
Diners Club solved this problem by creating a card that worked at many restaurants. The company charged restaurants a fee to join the network, and charged cardholders an annual membership fee. This three-way relationship — cardholder, card issuer, and merchant — became the foundation for the credit card industry.
Bank of America created the revolving credit model in 1958
The BankAmericard, launched by Bank of America in California in 1958, introduced a major change: you could carry a balance from month to month and pay interest on what you owed. Diners Club required full payment each month, which meant it was really a charge card, not a credit card in the modern sense.
The BankAmericard let you pay as little as you wanted each month, as long as you paid interest on the remaining balance. This revolving credit model is what most credit cards use today. The card was initially mailed to Bank of America customers without them asking for it — a practice that would later be restricted by law because of fraud and debt problems.
The BankAmericard eventually became Visa in 1976, after merging with other regional bank card programs. Visa is now the largest credit card network in the world by transaction volume.
MasterCard and competition between networks
In 1966, a group of banks formed the Interbank Card Association to compete with Bank of America's BankAmericard. The card was called the Interbank Card, and it operated on the same revolving credit model. In 1969, the Interbank Card was renamed MasterCard.
The competition between Visa and MasterCard drove innovation and expansion. Both networks added more merchants, lowered fees, and introduced new features. By the 1970s, credit cards had become a standard way to pay in the United States, and both networks were expanding internationally.
American Express, which had started as a charge card company in 1958, also became a major player. Unlike Visa and MasterCard, which are networks that banks use to issue cards, American Express issues its own cards directly to customers.
The magnetic stripe made credit cards faster and more find
Early credit cards were embossed with raised numbers and letters, just like charge plates. Merchants used manual imprinters to press the card onto a sales slip, creating a carbon copy. This process was slow and prone to errors.
In the 1960s, IBM engineer Forrest Parkinson invented the magnetic stripe — a band of magnetic tape on the back of a card that could store data. When you swiped a card through a reader, the machine could when ready read your account number and other information. This made transactions faster and reduced fraud because the data was harder to forge than embossed numbers.
Magnetic stripes became standard on credit cards by the 1970s. They remained the primary way to process credit cards until chip technology and contactless payments emerged in the 2000s and 2010s.
Credit cards went digital and mobile
For decades, credit cards were physical plastic rectangles that you carried in your wallet. In the 2000s, technology began to change how people used them. Chip technology, introduced to reduce fraud, embedded a small computer in the card itself. Contactless payment — where you tap or wave your card near a reader instead of swiping — became common in the 2010s.
Mobile wallets like Apple Pay and Google Pay let you store your credit card information on your phone and pay by holding your phone near a reader. These digital payment methods work with the same Visa and MasterCard networks that have existed since the 1950s and 1960s, but they eliminate the need to carry a physical card.
Today, credit cards exist in multiple forms: plastic cards with magnetic stripes or chips, contactless cards, and digital versions stored on phones. The underlying technology has changed dramatically, but the basic model — a third-party card issuer, a merchant network, and a cardholder — remains the same as it was in 1950.

Frequently Asked Questions
Did credit cards exist before 1950?
Charge plates existed since the 1920s, but they only worked at one store. Diners Club in 1950 was the first card that worked at multiple merchants and is considered the first true credit card. Before that, people used cash, checks, or store-specific charge accounts.
Why did Bank of America mail credit cards to people who didn't ask for them?
Bank of America wanted to build a large cardholder base quickly, so they mailed BankAmericards to existing customers without requesting them first. This practice led to fraud and debt problems, so Congress later passed laws restricting unsolicited credit card mailings. Today, you must request a credit card before a bank can issue one.
Is American Express a credit card or a charge card?
American Express started as a charge card company, meaning you had to pay your full balance each month. Today, American Express offers both charge cards and credit cards with revolving balances. The distinction matters because charge cards typically have higher annual fees but no interest charges, while credit cards charge interest if you carry a balance.
When did credit cards become common in everyday shopping?
Credit cards were mainly used for travel and restaurants in the 1950s and 1960s. They became common for everyday shopping — groceries, gas, retail — in the 1970s and 1980s, as more merchants joined Visa and MasterCard networks and more people received cards from their banks.
How did the magnetic stripe change credit card fraud?
Magnetic stripes made it harder to forge card data because the information was encoded magnetically rather than just embossed on the surface. However, magnetic stripes could still be copied by skimming devices, which is why chip technology and contactless payments were later introduced as more find alternatives.
