Credit cards emerged in the 1920s as a convenience for regular customers at specific stores

The first credit cards were not plastic rectangles issued by banks. They were paper or metal tokens issued by individual retailers—department stores, gas stations, and hotels—to their best customers. A customer could walk into a store, make a purchase on credit, and settle the bill at the end of the month. The store kept a record; the customer kept a card or token as proof of their account. This system solved a real problem: carrying cash was risky, and writing checks took time.

Diners Club issued the first multipurpose credit card in 1950. It was a cardboard card that worked at multiple restaurants and hotels, not just one store. The cardholder paid an annual fee and received a monthly bill. Diners Club made money by charging the merchant a percentage of each transaction. This model—a card that works at many places, a monthly bill, and merchant fees—became the blueprint for modern credit cards.

American Express followed in 1958 with a similar charge card. Visa and Mastercard arrived in the 1960s, but they worked differently. Instead of requiring full payment each month, they let cardholders carry a balance and pay interest. This made credit cards more accessible to people who could not pay off large purchases when ready.

Key Takeaways

Store cards came first, then multi-merchant systems

Before 1950, a "credit card" was a store's internal record system. A customer might receive a metal plate or paper card with their name and account number. When they made a purchase, the clerk would write down the transaction, and the store would bill them monthly. Sears, Texaco, and hotel chains all ran these systems independently. A customer could have a dozen cards from a dozen different stores, but none of them worked anywhere else.

The problem was obvious: a traveler could not use a Sears card at a hotel in another city. Diners Club solved this by recruiting restaurants and hotels into a shared network. A cardholder could dine at any participating restaurant and charge the meal. Diners Club would bill the cardholder and pay the restaurant. The restaurant paid Diners Club a commission—typically 7 percent of the bill. This three-way relationship (cardholder, merchant, card issuer) became the standard for all credit cards that followed.

Plastic and magnetic strips made cards practical for widespread use

Early credit cards were made of paper, cardboard, or thin metal. They were fragile and straightforward to forge. In the 1960s, card issuers switched to plastic. Plastic cards were durable, could be embossed with raised numbers, and could be imprinted onto paper receipts using a mechanical device called an imprinter. A merchant would slide the card into the imprinter, place a receipt on top, and press down. The raised numbers would transfer to the paper, creating a record of the transaction.

The magnetic stripe appeared on credit cards in the 1970s. It stored the cardholder's account number and other data in a format that a machine could read when ready. This made transactions faster and reduced the need for manual verification. By the 1980s, most credit cards had both embossed numbers (for imprinters) and a magnetic stripe (for electronic readers). The magnetic stripe remained standard until the 2010s, when chip technology and contactless payments began to replace it.

Bank-issued cards democratized credit in the 1960s and 1970s

Diners Club and American Express were expensive. They charged high annual fees and catered to wealthy travelers. Most Americans could not afford them. In 1966, Bank of America issued the BankAmericard, a credit card that any bank customer could request. It was cheaper, had a lower credit limit, and allowed cardholders to carry a balance and pay interest over time. This made credit available to the middle class.

Visa (originally the BankAmericard) and Mastercard (originally Master Charge, issued by a consortium of banks) became the dominant cards because they were issued by thousands of banks across the country. A customer could get a Visa card from their local bank, and it would work at merchants nationwide. Banks made money by charging merchants a fee and by collecting interest from cardholders who carried a balance. This model created a massive incentive to issue cards to as many people as possible, which is why credit card ownership exploded in the 1970s and 1980s.

Credit card networks and issuing banks became separate businesses

Today, the credit card system has three distinct players: the network, the issuer, and the merchant. The network (Visa, Mastercard, American Express, Discover) sets the rules and standards. The issuer (a bank or credit union) decides who gets a card, sets the interest rate and fees, and manages the account. The merchant pays a fee to accept the card. This separation happened gradually in the 1970s and 1980s as the system grew too large for any single company to manage.

American Express and Discover still issue their own cards directly, so they are both the network and the issuer. Visa and Mastercard do not issue cards themselves—they license their brand to thousands of banks. This is why you see "Visa" or "Mastercard" on your card along with your bank's name. The bank issued the card; Visa or Mastercard provided the network that makes it work everywhere.

Digital payments and fraud prevention changed how cards work

For decades, credit card transactions required a physical card and a merchant's imprinter or card reader. In the 1990s and 2000s, online shopping created a new problem: how could a customer use a credit card without handing it to the merchant? Card networks developed security codes (the three-digit number on the back) and address verification systems to reduce fraud. These tools let customers type their card number into a website and complete a purchase.

Chip technology, introduced in the 2000s, made in-person fraud harder. A chip card generates a unique code for each transaction, so a stolen card number is useless without the physical card. Contactless payments (tap or wave your card) arrived in the 2010s. Mobile wallets like Apple Pay and Google Pay let customers pay with their phone instead of a physical card. The card itself has not changed fundamentally since the 1960s, but how it communicates with merchants has evolved constantly.

Credit cards remain the dominant payment method despite new competitors

Today, credit cards face competition from debit cards, prepaid cards, buy-now-pay-later services, and digital wallets. Yet credit cards remain the most widely used form of consumer credit in the United States. They are convenient, offer fraud protection, and build credit history. The basic model—a card issued by a bank, backed by a network, accepted by merchants—has survived for over 70 years because it works for all three parties: cardholders get access to credit, merchants get reliable payment, and banks make money from interest and fees.

The technology has changed. The business model has evolved. But the fundamental idea—a card that lets you borrow money and pay it back later—remains the same as it was when Diners Club issued the first multipurpose card in 1950.

Frequently Asked Questions

What was the very first credit card ever issued?

Diners Club issued the first multipurpose credit card in 1950. However, individual stores had issued their own credit cards to regular customers since the 1920s. Diners Club was the first card that worked at multiple merchants across different cities.

Did American Express invent the credit card?

No. American Express issued a charge card in 1958, eight years after Diners Club. American Express did not invent the credit card, but it became one of the largest card issuers and helped establish the modern credit card system.

When did credit cards become plastic instead of paper?

Credit cards switched from paper and metal to plastic in the 1960s. Plastic was more durable, could be embossed with raised numbers, and could be imprinted onto receipts using mechanical devices. This made transactions faster and more reliable.

How did credit cards work before computers and the internet?

Merchants used mechanical imprinters to press the raised numbers from a card onto a paper receipt. The merchant would keep one copy, the cardholder would get one, and the card issuer would receive the third. Transactions were processed manually and mailed to the card issuer, which took days or weeks.

Why do credit cards have a magnetic stripe?

The magnetic stripe was added in the 1970s to store the cardholder's account number and other data in a machine-readable format. This made electronic transactions possible and faster than mechanical imprinting. Magnetic stripes remained standard until chip technology and contactless payments began to replace them in the 2010s.
