Merchants have to pay credit card transaction fees each time a card is swiped

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.

Why American Express charges merchants more than other card companies to accept AmEx

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.

Credit card companies make money through interest, annual fees, and more

They also profit from interchange fees, the fee the retailer has to pay the credit card network in order to facilitate a transaction. The fee is typically between 1% and 3% of the transaction amount.

American Express runs on a 'spend-centric' model, using perks and merchant fees to drive profit

American Express cardholders tend to spend more money per transaction than other credit card users, which makes the interchange fees merchants have to pay to accept American Express cards worth it while incentivizing other companies to pay the interchange fee as well.

American Express is both a card issuer and a processing network

Unlike most credit card companies, American Express issues credit cards and processes payments—something called a closed-loop model. By offering both services, American Express profits from both interest and interchange fees, and also has access to more data on how customers spend their money so it can offer better perks.

Card issuers are financial institutions that open credit to customers, while card networks facilitate purchases between merchants and customers

Card issuers give customers credit cards, set rate limits, and collect payments. Card networks, on the other hand, dictate where credit cards can actually be used by managing relationships between the network and merchants. These networks make money on interchange fees, which merchants pay to accept a specific card network at their stores.

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.

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%.

In 2018, the Supreme Court sided with American Express in a case that significantly changed antitrust regulation.

The US Department of Justice sued Visa, Mastercard, and American Express in 2010 over alleged anticompetitive contracts with merchants. While Visa and Mastercard settled out of court, American Express went to trial and had its case taken all the way up to the Supreme Court—which ruled that both sides of a transaction business must be analyzed to determine a monopoly.

American Express intentionally targets wealthy cardholders, who spend higher amounts per transaction and tend to make more transactions than the average cardholder, thereby reducing the company's risk.

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.

Charge cards are different from credit cards

Unlike credit cards, charge cards often don’t have a preset credit limit, but cardholders need to pay off the entire balance every month.

In 2025, American Express paid $230M to settle fraud and deceptive marketing charges

American Express launched a wire payment service targeted at small businesses and falsely touted the service as a tax-deductible business expense in 2018. American Express was also accused of allowing small businesses to open corporate credit cards without the necessary employer identification number (EIN).

Financial institutions check for lots of things before authorizing a purchase

Before authorizing a purchase, card issuers consider whether or not the cardholder has a high enough available credit limit to make the purchase, where the purchase is being made in order to reduce fraud, and more.

Why there are microchips in credit cards

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.

Gap and Sephora now accept BNPL, despite paying up to 8% per sale

Despite these merchants paying roughly 2% to 8% of each sale's cost (more than they pay for most credit card processing fees), they're signing on, in part, because BNPL can help them improve their conversion rates at checkout.

Who actually pays for your credit card rewards?

In 2018, 92% of all credit card spending was made on a rewards card, which seems like a good deal to many who apply for rewards cards offering discounted flights, points, and more. But in actuality, the customers are often the ones who end up paying for the rewards in the grand scheme of things.

BNPL companies typically make money via merchant fees rather than interest

When a merchant partners with a buy now, pay later app, consumers are more likely to spend more money with that merchant—meaning that the merchant is willing to pay a small fee in exchange for the ability for customers to pay with buy now, pay later.

Microchips in payment cards improve security by generating unique transaction codes

Magnetic strips store unchanging data that is easily cloned, but microchips act as miniature computers that encrypt sensitive data. They also resist fraud by creating data unique to each transaction, preventing duplication.

On credit and debit cards, magnetic stripes have been slowly replaced by microchips that use dynamic, encrypted data to prevent card cloning and counterfeit fraud.

The Platinum American Express card is among the most expensive mainstream travel credit cards

American Express charges a $895 annual fee on its Platinum Card in exchange for nearly $3.5K worth of credits and benefits. Some of the credits include a $600 for hotels, a $400 credit at restaurants with Resy, a $300 Lululemon credit, and even a $200 credit at Oura ring. (Some users may experience a paywall.)

Managing too many credit cards can be costly if they have annual fees

However, canceling cards must be strategic if it becomes necessary, as it can negatively impact your credit score. Before canceling, experts suggest asking if it's possible to downgrade to a no-annual-fee version in order to keep the account open, thus preventing potential hits to your credit score.

Some banks derive half of their income from overdraft fees on checking accounts

The fees are incurred when a customer withdraws more money than is left in the account, typically around $35 per overdraft. One in 11 Americans pays more than $350 a year in such fees, generating tens of billions of dollars each year for banks..

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.

Rewards credit cards can offer points, travel miles, and more

For every dollar that a cardholder spends on a rewards credit card, they can also receive benefits such as cash back, airline miles, and more. For many, rewards are the reason they make so many purchases on credit cards in the first place.

Fintech companies made it easier for merchants to request tips, leading to fatigue

In recent years, companies such as Square and Toast have created touch screen technologies prompting customers at coffee shops and casual restaurants to tip upwards of 25%. Despite the interesting psychological conundrum this presents to consumers, one tech columnist argues that shoppers don't need to succumb to the pressure.

Mutual funds come with a few associated fees.

American Express is credited with inventing the traveler's check

In the 1890s, then American Express President James C. Fargo was frustrated that he couldn't get cash while traveling in Europe outside of major cities. Marcellus Berry, an American Express employee, came up with the idea of a traveler's "cheque": a prepaid check, similar to cash, that requires the signature of both the customer and the receiving institution to be valid. American Express never modernized the spelling of the word "cheque" and stopped providing them at the end of 2020.

See an original Diner’s Club charge card

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.

American Express uses co-branded cards to provide brand-specific perks

Co-branded credit cards are partnerships between a card issuer and another company. Unlike regular credit cards that offer many different kinds of benefits at different companies, co-branded cards tend to only offer perks with the partner company. For example, American Express has a co-branded card with Delta airlines that allows users to earn points specifically towards the Delta rewards program.

Algorithms built to detect credit card fraud can deny charges if they perceive the attempted purchase is unfamiliar or unusual based on historical data, even when a person has enough credit to make the purchase.

Only 14% of transactions are in cash, as of 2025

Credit (35%) and debit (30%) cards have long eclipsed cash as the primary method of payment in the US. It is a primary backup, however, with 90% of customers intending to use cash to pay or store value and 80% carrying cash.

American Express debuted its first charge card in 1958 to give travelers access to cash abroad

The original American Express charge card was made of purple paperboard and allowed customers to book travel. Unlike credit cards, the card's balance had to be entirely paid off each month. When the card first launched, 250,000 customers used it, and 17,500 companies had agreed to accept it.

Gas stations top the list of riskiest places to use a debit card

Unlike credit cards, debit cards withdraw funds directly from your checking account, and federal laws provide fewer consumer protections against debit fraud. Gas station "skimmers" and long periods of separation from the card at restaurants are some of the more vulnerable spots for use.

American Express has acquired restaurant software companies to elevate its cardholder experience

One of the many perks of American Express cards is dining credits and special reservation access to fine dining restaurants. Since American Express cardholders are often more affluent than other credit card users, restaurants have benefited from increased partnerships with American Express to offer cardholders preferential reservations and premium experiences. In 2019, American Express acquired Resy, a reservation software, and went on to acquire Tock in 2024.

While the Fed is involved in issuing new generations of cash, the way it adds to the money supply does not involve printers

The majority of money in circulation is credit, not cash. This credit, which acts similarly to direct deposit from employers, is added to bank accounts by the Federal Reserve. The Fed also employs tools like the federal funds rate and open market operations to expand or contract credit.

Why Americans are drowning in credit card debt

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.

American Express is targeting Gen Z, who are generally less risk-averse than older generations

Unlike Millennials, who grew up during the Great Recession in 2008, Gen Z has a higher risk appetite and has grown up with more gamified spending platforms, like online gambling and prediction markets. Analysts say Gen Z's risk appetite makes them prime targets for credit card companies like American Express that can sell younger customers on large benefits in exchange for annual fees.

Tariffs are typically paid by the importing company or organization to the US Treasury.

The costs and fees for a payday loan include a 'finance charge'

Payday lenders typically make money via finance charges, a percentage or dollar amount that the borrower owes the lender per $100 borrowed. While the finance charge can range from $10 to $30 for every $100 borrowed, this would equate to an annual percentage rate of almost 400 percent for a two-week loan.

Credit card issuers determine your credit limit using your payment history, income, and more

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.

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.

The 'Centurion' card is American Express' highest-tier, invite-only credit card.

An explanation of hard credit checks vs. soft credit checks

Some buy now, pay later services do a soft credit check rather than a hard credit check, like credit card companies would do when someone applies for a card. While hard credit checks can impact your credit score, soft pulls typically do not.
