Credit cards have existed in some form for over a century, though they looked nothing like today's plastic cards
The first credit card systems appeared in the late 1800s, when department stores and gas stations issued charge plates — metal rectangles embossed with a customer's name and account number. A clerk would place the plate in a machine that pressed the information onto a paper receipt. The customer paid the store monthly, not the card issuer. These were store-specific: a Sears plate worked only at Sears.
The modern credit card — a card that lets you borrow money from a bank to pay any merchant — arrived in the 1950s. Diners Club issued the first general-purpose card in 1950, followed by American Express in 1958 and Visa (originally called BankAmericard) in 1958. These cards worked at many merchants, not just one store, and the card issuer, not the merchant, extended the credit.
The shift from metal plates to plastic happened gradually through the 1950s and 1960s. Plastic was cheaper to produce, easier to mail, and less likely to damage a merchant's imprinting machine. By the 1970s, plastic had become standard.
Key Takeaways
- Charge plates, the predecessors to credit cards, appeared in the late 1800s and worked only at a single store.
- Diners Club created the first general-purpose credit card in 1950, which could be used at multiple merchants.
- Visa and American Express launched their own cards in the late 1950s and expanded the credit card market beyond wealthy travelers.
- Plastic replaced metal as the standard card material during the 1950s and 1960s because it was cheaper and more practical.
How charge plates worked differently from today's cards
A charge plate was a metal rectangle, usually about the size of a modern credit card, embossed with the customer's name and account number. When you made a purchase, the clerk placed your plate in a manual imprinting machine and pressed it against a carbon receipt. The machine transferred your account information onto the paper.
The key difference: you paid the store directly, not a bank. The store extended the credit to you as a customer, and you settled your bill with them monthly. There was no separate card issuer making money from interest. Stores used charge plates to encourage repeat business and to track which customers owed them money.
Charge plates were also merchant-specific. A Texaco plate worked at Texaco stations. A Sears plate worked at Sears. If you wanted to shop on credit at multiple stores, you needed multiple plates.
Why Diners Club changed the credit card model
Diners Club, founded in 1950, introduced a card that worked at many restaurants and hotels, not just one business. The card issuer — Diners Club itself — paid the merchant on your behalf, and you paid Diners Club monthly. This was revolutionary because it meant a single card could be used across different businesses.
Diners Club targeted wealthy travelers who ate at upscale restaurants and stayed at hotels. The card solved a real problem: you could leave your wallet at home and pay with a card instead. The company made money by charging merchants a percentage of each transaction (called an interchange fee) and by charging cardholders an annual membership fee.
American Express followed in 1958 with a similar model, and Visa (then called BankAmericard) launched the same year. Visa's innovation was that it was issued by banks, not a single company, which allowed it to spread faster across the country. By the 1960s, credit cards had moved beyond luxury goods for the wealthy into mainstream use.
The shift from metal to plastic in the 1950s and 1960s
Early credit cards were still made of metal or cardboard because merchants were already using metal imprinting machines designed for charge plates. Plastic was introduced gradually as new machines were built to handle it.
Plastic had clear advantages: it was cheaper to manufacture, lighter to mail, and less likely to jam or damage a merchant's equipment. By the mid-1960s, plastic had become the standard. The plastic card also allowed for a magnetic stripe on the back, which could store more information than an embossed number and made transactions faster.
How the magnetic stripe changed credit card technology
The magnetic stripe, introduced in the 1960s, was a thin band of magnetic material on the back of the card that could store data — your account number, expiration date, and other information. Instead of manually reading an embossed number, a merchant could swipe the card through a reader that instantly pulled up your account information.
This made transactions faster and reduced errors from manual entry. It also made credit cards more portable: you no longer needed a heavy imprinting machine at every checkout. A small magnetic stripe reader could process a transaction in seconds.
The magnetic stripe remained the standard for decades. It was not until the 2000s that chip technology (an embedded microchip that stores encrypted data) began replacing it in the United States, making cards harder to counterfeit.
The move to digital payments and contactless cards
Starting in the 2000s, credit card companies began adding contactless payment technology — a chip that lets you tap your card near a reader instead of inserting it or swiping. This technology uses radio waves to transmit your payment information securely.
Around the same time, smartphones began storing credit card information through digital wallet apps like Apple Pay and Google Pay. You can now pay with your phone instead of a physical card. The underlying technology is the same — the card issuer still extends credit and you pay them back — but the delivery method has changed.
Despite these innovations, physical credit cards remain common. Many people carry both a physical card and use digital payment methods depending on the situation.
Why credit cards took so long to become widespread
Even after Diners Club and American Express launched in the 1950s, credit cards spread slowly. Many merchants did not want to pay the interchange fee (the percentage of each transaction that goes to the card issuer). Small businesses especially resisted because the fee cut into their profit.
Consumers were also hesitant. Credit cards required trust in a new system: you had to believe the card issuer would not lose your information, that your monthly bill would be accurate, and that you could dispute a fraudulent charge. Building that trust took time.
Visa's decision to license the card to banks rather than issuing it centrally was crucial to widespread adoption. Banks already had relationships with customers and merchants, so they could promote the card more effectively. By the 1970s, credit cards had become mainstream in the United States.
Frequently Asked Questions
What was the very first credit card ever made?
Diners Club issued the first general-purpose credit card in 1950. However, charge plates — store-specific metal cards — existed since the late 1800s. Charge plates are the true ancestors of modern credit cards, but they only worked at one store.
When did credit cards become plastic instead of metal?
Plastic gradually replaced metal during the 1950s and 1960s. Early credit cards were still made of metal or cardboard because merchants had machines designed for those materials. By the mid-1960s, plastic had become standard because it was cheaper, lighter, and compatible with new magnetic stripe technology.
How did people pay before credit cards existed?
Before credit cards, people paid with cash or check. Department stores and gas stations offered charge plates that let you buy on credit and pay the store monthly. Wealthy travelers could use American Express traveler's checks, which were prepaid and could be cashed at hotels and merchants worldwide.
Do credit cards work the same way now as they did in the 1950s?
The basic model is the same: a card issuer extends credit, you use the card to make a purchase, and you pay the issuer back monthly. The technology has changed dramatically — from embossed metal plates to magnetic stripes to chips to digital wallets — but the underlying system remains recognizable from the 1950s.
