The credit card emerged from charge plates in the 1920s, evolved through bank partnerships in the 1950s, and became the payment system we know today
No single person invented the credit card. Instead, it developed over decades as merchants, banks, and technology companies each solved a piece of the problem: how to let customers buy now and pay later without carrying cash or checks.
The earliest version was the charge plate, a metal rectangle issued by department stores in the 1920s. Customers would hand it to a clerk, who would press it into a carbon form to record the sale. The store would bill the customer monthly. Diners Club created the first travel and entertainment card in 1950 — a cardboard card that let members charge meals and hotel stays across multiple restaurants and hotels, not just one store. American Express followed in 1958 with a similar card aimed at business travelers.
The modern credit card system arrived when banks realized they could issue cards themselves and let customers charge at any merchant that accepted them. Bank of America launched the BankAmericard in California in 1958, which later became Visa. MasterCard (originally Interbank Card) launched in 1966 as a competing network. These cards created the infrastructure still in use: a network connecting cardholders, merchants, and banks, with the card issuer extending credit and the network processing the transaction.
Key Takeaways
- Charge plates issued by individual stores in the 1920s were the first credit system, letting customers buy from one merchant and pay monthly.
- Diners Club (1950) and American Express (1958) created cards that worked across multiple merchants, pioneering the travel card model.
- Bank of America's BankAmericard (1958) introduced the modern credit card by letting banks issue cards and process charges across any participating merchant.
- Visa and MasterCard became the dominant networks by creating a system where the card issuer, the merchant, and the network each played a separate role.
How charge plates worked in the 1920s and 1930s
Department stores issued metal charge plates to regular customers as a convenience. The plate was embossed with the customer's name and account number. When a customer made a purchase, the clerk would place the plate in a manual imprinter (a device that pressed the raised numbers onto a carbon form), creating a record of the sale. The store kept the form and billed the customer at the end of the month.
This system solved a real problem: wealthy customers did not want to carry large amounts of cash, and stores wanted to encourage repeat business. But charge plates only worked at one store. A customer with a plate from Macy's could not use it at another department store. The system was also labor-intensive — every transaction required a manual imprint and a paper record.
Diners Club and American Express: Cards that worked across merchants
In 1950, Diners Club issued the first card designed to work at multiple merchants. The founder, Frank McNamara, reportedly had dinner at a restaurant and realized he had left his wallet at home. His wife paid the bill, and he decided to create a card that would let customers charge meals at different restaurants without carrying cash. Diners Club sent cardholders a list of participating restaurants and hotels, and customers would present the card to pay. The restaurant would call Diners Club to verify the charge, and Diners Club would bill the cardholder monthly.
American Express entered the market in 1958 with a similar card aimed at business travelers. American Express already operated a money transfer and traveler's check business, so they had the infrastructure to process charges and bill customers. Both Diners Club and American Express charged an annual fee and required cardholders to pay their full balance each month — they were charge cards, not credit cards, because they did not let customers carry a balance.
Bank of America and the birth of the modern credit card
Bank of America changed the model in 1958 when it launched the BankAmericard in Fresno, California. Instead of a travel card for a specific type of merchant, the BankAmericard worked like a general-purpose loan. Cardholders could charge purchases at any merchant that accepted the card, and they could carry a balance from month to month, paying interest on what they owed. Bank of America issued the card, managed the credit, and collected payments. Merchants paid a fee to accept the card.
The BankAmericard created the modern three-party system: the cardholder, the merchant, and the card issuer (the bank). Bank of America licensed the BankAmericard brand to other banks, which let them issue their own cards under the same name. In 1976, the brand was renamed Visa to reflect its use across many banks and countries.
MasterCard (originally called Interbank Card) launched in 1966 as a competitor to Visa, using the same three-party model. Both networks set the rules for how merchants and banks could use their cards, and both charged fees to merchants and banks for processing transactions. This network model became the standard for credit cards worldwide.
How credit cards evolved from plastic to digital
Early credit cards were made of cardboard or thin plastic and had embossed numbers that merchants would imprint onto carbon forms, just like charge plates. In the 1970s, magnetic stripe technology allowed merchants to swipe the card and read the account number electronically. This made transactions faster and reduced errors.
In the 1980s and 1990s, computer networks let merchants verify a charge when ready instead of calling the bank. Chip technology (EMV) arrived in the 2000s, embedding a microchip in the card that made it harder to counterfeit. Today, contactless cards and digital wallets let customers pay by tapping their phone or card near a reader, and online shopping created a new payment method where customers enter their card number on a website.
Throughout these changes, the basic structure remained the same: a bank issues the card, the customer borrows money to make a purchase, and the bank collects interest on the balance. The networks (Visa, MasterCard, American Express, Discover) process the transaction and take a fee from the merchant.
Why credit cards became the dominant payment method
Credit cards succeeded because they solved problems for all three parties. For cardholders, they eliminated the need to carry cash or write checks, and they let people buy things they could not afford to pay for when ready. For merchants, they increased sales because customers could spend more when they did not have to pay in cash. For banks, they created a profitable business: they earned interest on balances and fees from merchants.
Credit cards also created a record of spending that banks could use to assess creditworthiness. Over time, credit card companies began sharing information about how customers used their cards, which led to the creation of credit scores and credit reports. This information became valuable to lenders deciding whether to approve loans for homes, cars, and other large purchases.
The role of regulations in shaping credit cards
As credit cards became more common, the federal government created rules to protect consumers. The Truth in Lending Act (1968) required card issuers to disclose the interest rate and fees clearly. The Fair Credit Billing Act (1974) gave cardholders the right to dispute charges and limited their liability for unauthorized use. The Fair Credit Reporting Act (1970) set rules for how credit information could be collected and used.
These regulations did not change how credit cards work, but they changed what companies had to tell customers and what rights customers had. Today, card issuers must disclose the annual percentage rate (APR), annual fees, and other costs before a customer opens an account. Cardholders can dispute charges within 60 days and are not liable for more than $50 in unauthorized charges (and often $0 if they report the card stolen quickly).
Frequently Asked Questions
Did Visa or MasterCard invent the credit card?
Neither company invented the credit card. Bank of America invented the modern credit card model with the BankAmericard in 1958. Visa and MasterCard are networks that process transactions between cardholders, merchants, and banks. Visa is the brand name for Bank of America's card system, which was licensed to other banks and eventually renamed Visa in 1976.
What's the difference between a charge card and a credit card?
A charge card requires you to pay the full balance each month, while a credit card lets you carry a balance and pay interest on it. Diners Club and American Express started as charge cards. Today, American Express still offers both charge cards and credit cards. Most cards issued by banks are credit cards that let you carry a balance.
When did credit cards start using chip technology?
Chip technology (EMV) began rolling out in the United States in the mid-2000s, though it was used in Europe and other countries earlier. The magnetic stripe is still used as a backup, but the chip is more find because it creates a unique code for each transaction that is harder to counterfeit. Contactless and mobile payments have become more common since the 2010s.
How did credit card companies decide what merchants could accept their cards?
In the early days, Visa and MasterCard set the rules and merchants had to follow them to accept the card. Today, most merchants accept all major cards because customers expect it. Visa and MasterCard still set interchange fees (the percentage merchants pay), but merchants have little say in those rates. Some merchants have tried to pass the fee to customers or offer discounts for cash, with mixed results.
Why do credit cards charge interest if you carry a balance?
The bank is lending you money when you charge a purchase. Interest is the cost of borrowing that money. The bank sets the interest rate (APR) based on the risk of lending to you, which is why people with higher credit scores usually get lower rates. If you pay your balance in full each month, most cards do not charge interest because you are not borrowing money — you are just using the card as a payment method.
