Arguably the biggest financial innovation of the past 100 years, credit cards are familiar pieces of metal or plastic that allow cardholders to borrow funds to pay for goods and services.
Hours of research by our editors, distilled into minutes of clarity.
We unpack how your $5 latte triggers a global relay between banks and networks like Visa and Mastercard, trace the 1958 campaign that jump-started the credit card revolution, and reveal how a trillion-dollar system quietly shapes the way we spend.
Every tap sets off a lightning-fast relay. When I buy coffee with my Visa, a tiny “runner” races between the coffee shop’s bank, Visa’s network, and my bank—all in under a second. The catch? No money has actually moved yet. Here’s what really happens behind that instant “Approved.”
Credit cards have evolved significantly since their invention in 1950, but security lagged in the US for years. Despite handling only a quarter of global transactions, the US once accounted for half of all credit card fraud. The 2013 Target data breach helped push the adoption of chip cards, reducing fraud but shifting risks to online scams.
Some credit card issuers also take your other payment obligations into account when determining your credit limit, such as the cost of your rent or alimony.
US consumer debt nationwide totaled $17.9T as of 2024 Q3. Mortgage debt ranked as number one, with student loan debt coming in at number two.
Before credit cards, there were charge cards from companies like Diner’s Club. While credit cards allow cardholders to carry a balance from month to month (potentially accruing interest), charge cards like Diner’s Club cards had to be paid off right away.
Unlike credit cards, charge cards often don’t have a preset credit limit, but cardholders need to pay off the entire balance every month.
Americans owe more than $1T to credit card companies. And with rising interest rates that prevent cardholders from paying down debt (not to mention the rising cost of living), that number is likely to keep growing. A podcast episode explains how the US got here, and what policymakers and individuals can do about it.
Visa has the highest credit card market share by purchase volume, coming in at 52.2%, followed by Mastercard at 24.9%.
Americans reached an all-time high debt burden in 2024. Data compiled from The Kaplan Group shows the evolution of auto loans, mortgages, credit card debt, and student loans from 2003 to 2023, and finds that after a brief decline after 2008, the total debt burden grew rapidly.
The United States is home to more than 33 million businesses, the vast majority of which are small businesses, with millions being created (and others closing shop) every year. These businesses often rely on loans, provide the goods and services that keep the economy flowing, and sometimes even grow large enough to enter public markets or provide private investment opportunities.
