Visa

Listen to a podcast episode from 1440's editor in chief that explains how a credit card transaction works behind the scenes.

When you buy even something as small as a $5 latte, a global relay between banks and networks like Visa and Mastercard is triggered. It all started with a 1958 campaign from Bank of America that jump-started the credit card revolution.

Visa, the first credit card network, still dominates competitors with a roughly 52% market share by purchase volume.

Among the major credit card companies in the US, Mastercard had about 25% of the market share in 2025. American Express had roughly 20%, and Discover had the smallest market share of about 4%.

The name Visa was conceived by the company's founder, Dee Hock.

Visa was previously called National BankAmericard Inc. (NBI), but as other banks began to license the network and it expanded internationally, it needed a name less associated with both Bank of America and America itself. Hock believed that the word "Visa" implied no national identification and was relatively easy to pronounce in any language.

Bank of America helped establish Visa as a global credit card network business after it rolled out its first credit cards.

At the time, those credit cards were called "BankAmericards." Today, Bank of America owns less than a 2% share of Visa—many other banks (as well as institutional investors) help govern and profit from the network.

Roughly 39% of Visa's revenue comes from data processing fees.

Visa gets roughly 0.13% to 0.14% of each transaction. About 32% of its revenue stems from the money banks pay Visa to use its services, and roughly 26% of its revenue comes from international transaction fees.

Watch a video that visualizes what really happens inside a credit card network when you make a purchase.

Every tap sets off a lightning-fast relay. When someone buys coffee with their Visa, a tiny "runner" races between the coffee shop's bank, Visa's network, and their bank—all in under a second. The catch? No money has actually moved yet. Here's what really happens behind that instant "Approved."

Visa Founder Dee Hock abruptly left the credit card company in 1984, saying his inner voice told him that business, power, and money are not what life is about.

The history of credit cards begins with the 'Fresno Drop.'

On a 1958 morning in Fresno, California, about 60,000 people woke up to find a strange rectangular piece of plastic on their doorstep without explanation. Those chosen for the "Fresno Drop" didn't know it yet, but Bank of America was behind the credit card delivery stunt.

American Express charges merchants more than other card companies to accept AmEx, making Visa a more accessible option for many merchants.

Each card network charges merchants a discount rate, which is a fee merchants pay to accept cards. American Express charges higher discount fees than competitors like Visa and Mastercard as the business is more reliant on fees for operation.

Stablecoins now transfer more value than Visa or Mastercard.

Because stablecoins operate on public blockchains, transfers can occur nearly instantly without intermediaries, unlike traditional credit card networks. This has fueled stablecoins' adoption within the crypto world and in cross-border payments. Stablecoin transfer volume rose from about $3B in 2018 to roughly $18T in 2024, overtaking Visa's roughly $16T and Mastercard's $10T.
