Visa & Mastercard: the companies getting paid every time you tap your card

Every time you tap your card to buy a coffee, book a flight or pay for your groceries, there’s a good chance two companies you’ve probably overlooked are making money.

Visa and Mastercard don’t lend you money or hold your savings. Instead, they get paid because they operate the networks that move money every time a bank-issued card is used.

It’s an important distinction and one that’s easy to miss. Visa and Mastercard aren’t banks. They’re payment networks. Think of them as the tollbooths on one of the world’s busiest financial highways, collecting a small fee every time a transaction travels across their rails.

That difference shapes almost everything about their business. It explains how they make money, where the risks sit and why investors might think about them very differently from traditional banks.

The invisible network behind every tap

Most card payments involve more than just you and the business you’re buying from.

Behind the scenes, there are usually four key players: you, the bank that issued your card, the merchant and the merchant’s bank. Sitting somewhere in the middle is Visa or Mastercard, authorising the payment and securely routing information between the two banks in a matter of seconds.

It all happens so quickly that most of us never think about it.

Take a $100 purchase. The merchant doesn’t receive the full $100. Part of the payment goes to the bank that issued your card. Another small slice goes to Visa or Mastercard for operating the payment network, while the merchant’s bank keeps its own fee for processing the transaction.

Visa and Mastercard only receive a small portion of each payment. But when those payments happen billions of times every year, those small fees add up.

Why Visa and Mastercard aren’t banks

Once you understand that Visa and Mastercard are infrastructure businesses rather than lenders, the next question becomes obvious: where do they actually make their money?

The easiest way to understand Visa and Mastercard is to first understand what they’re not.

Banks lend money. They accept deposits. They take on the risk that borrowers won’t repay their loans and earn much of their profit from the difference between the interest they charge borrowers and the interest they pay depositors.

Visa and Mastercard do none of those things.

If someone doesn’t repay their credit card balance, Visa and Mastercard don’t absorb that loss. The issuing bank does.

That means the payment networks don’t carry large loan books or rely on interest income in the way banks do. Instead, their earnings are driven by how much spending flows across their networks, how much cross-border activity takes place and how many additional services they can sell alongside the payment itself.

It’s a more asset-light model that depends on facilitating transactions rather than financing them.

Where the money comes from

At first glance, collecting a tiny fee on every payment might not sound especially exciting.

But scale is what turns small fees into meaningful revenue.

Visa and Mastercard process trillions of dollars in payment volume every year across consumers, businesses and governments worldwide.

Most of their revenue comes from four sources:

• Domestic payment volume
• Cross-border payment volume
• Data processing and transaction services
• Value-added services such as fraud prevention, tokenisation and analytics

Cross-border spending is one area that is critical to their businesses.

Think international holidays, overseas shopping or booking flights with foreign airlines. These transactions generally attract higher fees than domestic payments, making them highly valuable to the networks.

Another increasingly important revenue source sits beyond the payment itself.

Both companies are expanding their value-added services businesses, offering banks and merchants products like fraud detection, cybersecurity, tokenisation, consulting and data analytics.

That matters because it means they’re earning more than just a fee every time someone taps their card. They’re increasingly monetising the technology and infrastructure built around the payment ecosystem itself.

Why the moat has been so hard to crack

If collecting a fee on billions of transactions is such an attractive business, why hasn’t someone simply built a better network?

The answer comes down to three powerful competitive advantages.

1. Network effects

Payments are one of the clearest examples of a network effect.

Consumers want to carry cards that are accepted almost everywhere. Merchants want to accept the cards that most customers already use.

That creates a self-reinforcing cycle that’s difficult for new entrants to break. A new network needs both merchants and consumers to adopt it at the same time, but each group is reluctant to move until the other already has.

Scale becomes an advantage that grows stronger over time.

2. Switching costs

Building a payment network isn’t just about processing transactions.

Banks, merchants and payment providers have spent decades integrating fraud controls, settlement systems, compliance processes and operational infrastructure around Visa and Mastercard.

Replacing those systems isn’t impossible, but it is expensive, operationally risky and time consuming.

That creates meaningful switching costs, even if an alternative network offers lower fees.

3. Trust

Perhaps the biggest advantage is one that’s hardest to measure.

Consumers expect their card to work every time they tap it. Merchants expect payments to clear quickly and securely. Banks expect fraud systems to operate reliably at enormous scale.

Decades of investment in security, resilience, tokenisation and fraud prevention have built a level of trust that’s difficult to replicate.

When you’re moving trillions of dollars every year, reliability becomes one of the network’s most important competitive advantages.

What could put pressure on Visa and Mastercard business?

Even businesses with strong competitive advantages aren’t immune to pressure.

For Visa and Mastercard, the biggest risks come from two directions: regulation and alternative payment systems.

The regulatory challenge isn’t hypothetical. 

Visa and Mastercard are working through a US$38 billion settlement with U.S. merchants over claims the networks charged excessive fees to process credit card payments, part of a legal dispute that has already run for years and seen at least one earlier settlement attempt rejected by the courts as insufficient. 

The current agreement has cleared preliminary court approval, but merchant groups have signalled they may still challenge aspects of it, so the final outcome and its long-term effect on interchange economics remain unresolved.

That’s the broader takeaway. Highly profitable businesses sitting at the centre of global payment infrastructure are likely to remain under regulatory scrutiny for years to come.

The next challenge: alternative payment rails

Regulation isn’t the only force worth watching.

Over the longer term, new ways to pay could gradually reduce the amount of spending flowing across traditional card networks.

Real-time account-to-account payment systems are one example. Instead of routing a payment through Visa or Mastercard, these systems allow money to move directly between bank accounts, often in seconds. Australia already has the New Payments Platform (NPP), while other markets have developed similar infrastructure.

Buy now, pay later (BNPL) is another. BNPL providers can reduce the role of traditional credit cards in some purchases, routing a portion of consumer spending around the card networks entirely.

None of these alternatives look close to replacing Visa or Mastercard across the broader payments ecosystem today. Consumers value the convenience, fraud protection and near-universal acceptance that cards offer. Merchants have built their systems around them. Banks continue to issue them at enormous scale.

That doesn’t mean new payment technologies should be dismissed altogether. The more useful question is will enough payment volume gradually shifts elsewhere over time to chip away at the economics of the existing networks.

Blockchain and stablecoins: threat or infrastructure upgrade?

Stablecoins deserve a closer look because both Visa and Mastercard have moved well beyond treating them as a distant threat. Increasingly, they’re helping build the infrastructure themselves.

Visa has expanded its stablecoin settlement pilot program to support stablecoin-linked card programs across more than 50 countries and also introduced a beta version of a broader Visa Stablecoin Platform, designed to help financial institutions integrate stablecoins into everyday payment and settlement operations.

Mastercard has taken a similar path, acquiring stablecoin infrastructure firm BVNK to extend its own settlement capabilities, with plans to expand stablecoin settlement optionality across the United States and Latin America through 2026.

The key point is that neither company is sitting back waiting to be disrupted.

Instead, both are positioning themselves to support stablecoin settlement if adoption continues to grow. That said, both programs remain pilots and partial rollouts rather than the primary way transactions are settled.

The more useful way to think about it isn’t whether blockchain replaces Visa and Mastercard, but whether the two companies successfully make themselves the layer stablecoin activity settles through, rather than losing that settlement volume to a rail they don’t control.

The bear case

Visa and Mastercard are often cited as examples of high-quality businesses, reflecting their long history of profitability and consistent earnings growth.

That’s also where the bear case begins.

Great businesses don’t always make great investments if the price already assumes years of future growth.

Both companies have enjoyed years of strong payment growth, expanding profit margins and significant share buybacks. Their share prices have reflected much of that success.

Cross-border spending has been another important driver, particularly as international travel recovered following the pandemic. 

But growth rates can slow.

The second part of the bear case is regulation.

A highly profitable duopoly operating at the centre of global payments will almost always attract political and regulatory attention.

The proposed US$38 billion merchant settlement is one example, but it’s unlikely to be the last.

Governments around the world continue to review payment fees, competition and consumer protections. Future regulatory changes could reduce parts of the industry’s fee pool, even if the underlying demand for electronic payments continues to grow.

None of this necessarily means the investment case is broken.

It simply means investors shouldn’t assume today’s growth rates or fee structures will continue indefinitely.

Why Visa and Mastercard investors still keep coming back

Despite those risks, it’s easy to see why different types of investors continue to follow these companies closely.

Both businesses benefit from one of the most enduring trends in the global economy: the gradual shift from cash to digital payments.

Every time someone chooses to tap a card instead of paying with cash, shop online instead of in-store or travel internationally, there’s another opportunity for the payment networks to earn a fee.

Their earnings are driven much more by payment volumes, than by the credit cycle that shapes a traditional lender’s results.

Rather than being primarily exposed to credit quality, investors in these companies gain exposure to the growth of digital commerce.

Two businesses with more similarities than differences

It’s easy to compare Visa and Mastercard as rivals, but in practice they’re structurally similar businesses.

Both operate global four-party payment networks.

Both benefit from the same long-term shift towards electronic payments.

Both continue investing heavily in fraud prevention, cybersecurity and value-added services.

And both enjoy powerful network effects that make it difficult for competitors to replicate their scale.

The differences are more about emphasis than business model.

The choice of one rather than the other, is largely a judgement about execution rather than two fundamentally different business models.

Visa remains the larger company by payment volume and processed transactions, reflecting decades of relationships with financial institutions around the world.

Mastercard has generally built a larger value-added services business as a proportion of its overall revenue, giving it somewhat greater exposure to software, data and advisory services alongside payments.

Their geographic footprints also differ, reflecting different partnerships with banks across regions over many years.

What would change the investment story?

Travel demand has always been influenced by economic conditions, seasonality and geopolitical events. Short-term fluctuations are part of the business.

One soft quarter of cross-border spending isn’t enough to overturn any long-term investment case.

Instead, investors may be better served by watching for persistent changes over time.

Some of the questions worth asking include:

• Is payment volume consistently growing in line with the broader economy?
• Are regulators pushing interchange rates materially lower than current expectations?
• Are alternative payment systems starting to take meaningful market share?
• Is growth in value-added services slowing as those businesses mature?
• Is stablecoin settlement volume increasingly moving through rails that Visa and Mastercard don’t control, rather than through the settlement infrastructure they’re building themselves?

Looking at these trends over several quarters is generally more informative than reacting to a single earnings report. They’re simply the key signposts worth monitoring as the payments landscape continues to evolve.

The bottom line

It’s easy to think of Visa and Mastercard as credit card companies.

In reality, they’re something quite different.

They’re the infrastructure sitting behind billions of everyday purchases, quietly moving money between banks every time someone taps, swipes or shops online.

Their success isn’t built on lending money or collecting deposits. It’s built on facilitating commerce.

Those characteristics have contributed to consistently high profitability over many years.

The opportunity isn’t simply that people will keep paying electronically. That trend is already well established.

It is whether Visa and Mastercard can continue capturing a meaningful share of that growing payment volume and of the emerging settlement rails like stablecoins, while expanding the higher-value services, all without regulation or emerging competitors materially changing the economics of the business.

In many ways, Visa and Mastercard don’t need consumers to spend more than ever before. They simply need more of the world’s spending to keep flowing through their networks.

That’s a remarkably durable business model.

Whether it’s a remarkable investment depends on the price that an investor is willing to pay.
