Money is moving differently now. Account-to-account payments, A2A for short, let you send money directly from your bank to someone else's bank, instantly, with no card, no middleman, no Visa, no Mastercard. Just bank to bank.

It sounds simple because it is. And that simplicity is threatening to upend a global payments industry worth trillions. Global A2A transactions are projected to rise from $1.7 trillion in 2024 to $5.7 trillion by 2029, and Europe is leading the charge.

What Is An A2A Payment?
Think of A2A payment, short for account-to-account payment, as sending money the direct way. Instead of your money traveling through a card network like Visa or Mastercard, making stops along the way and picking up fees at each one, it goes straight from your bank account to the recipient's bank account. No card. No intermediary. No detour.

It is the digital equivalent of handing someone cash, except it happens in seconds, from your phone, from anywhere in the world.

For merchants, A2A transactions can be up to 80% cheaper than card payments due to the elimination of interchange fees, resulting in substantially lower processing costs.

That saving gets passed along the chain, and for businesses billing clients, managing international payments, or receiving regular income, the difference is significant.


How Does It Work?
Step 1 — You choose to pay. At checkout or in your banking app, you select the pay-by-bank or A2A option.

Step 2 — You get redirected. Your bank's app or website opens automatically. Nothing gets typed in manually.

Step 3 — You authenticate. You confirm who you are — usually with a fingerprint, face ID, or a one-time code.

Step 4 — Payment is sent. The money leaves your account and arrives in the recipient's account. In most cases this happens in seconds.

Step 5 — Done. No card number shared. No processing delay. No fee eaten by a card network.

This mobile-native solution leverages Strong Customer Authentication protocols, requiring customers to verify their identity through multiple factors such as biometrics or one-time passwords.

The result is a payment that is faster, cheaper, and arguably more secure than the card-based alternative most people have used their entire lives.

What Are Some A2A Payment Providers?
You probably already use A2A payments without knowing it. Here are some real-world examples:
iDEAL in the Netherlands — When you shop online in the Netherlands and pay directly through your bank app, that is A2A. iDEAL processes hundreds of millions of transactions a year.

BLIK in Poland — You generate a 6-digit code in your banking app and enter it at checkout. The money moves directly from your account to the merchant's. No card involved.

Pix in Brazil — Brazil's central bank built Pix in 2020. Pix has seen P2B transactions grow by 209% between 2021 and 2022, and it now accounts for 24% of the country's e-commerce transactions.

UPI in India — India's Unified Payments Interface handles billions of transactions monthly, allowing anyone with a bank account to pay instantly using just a phone number or QR code.

Swish in Sweden, Bizum in Spain, Vipps in Norway — all A2A systems built by local banks, widely used by everyday consumers for splitting bills, paying merchants, and sending money to friends.
Why Is Account-To-Account Evolving So Rapidly?
Because it solves three problems that have frustrated merchants and consumers for decades: cost, speed, and complexity.

Cost. Traditional card payments incur interchange fees, scheme fees, and acquirer markups resulting in total costs of 0.3–3% depending on merchant size and card type. By contrast, A2A payments typically cost between 0.1–0.5%. For a business processing a million dollars in payments, that difference is tens of thousands of dollars a year.

Speed. Card payments settle in one to three business days. A2A payments settle in seconds, 24 hours a day, seven days a week. Better cash flow, less waiting, less uncertainty.

Simplicity. No card number to type. No expiry date. No CVV. No card to lose or have cloned. Just your banking app, which you already trust.

Add to this the rise of Open Banking, where banks are required by regulation to share customer data securely with third-party providers, and you have the perfect conditions for A2A to thrive. Regulation is building the highway. Technology is the engine. Consumer trust is growing fast.

Where Is A2A Payments Growing The Fastest?
Europe is the leader. In 2025, analysts are foreseeing a 30% growth in Europe's A2A payment volumes. Countries like the Netherlands, Poland, Sweden, and Spain already have mature A2A systems with tens of millions of active users.

The EU's SEPA Instant Credit Transfer regulation is now mandating that banks across the eurozone offer instant payments, which means A2A is becoming infrastructure, not just an option.

Asia is accelerating fast. India's UPI and China's Alipay/WeChat Pay dominate. Strong growth is predicted for Indonesia with a CAGR of 81.9% between 2022 and 2027, Malaysia at 19.7%, the Philippines at 18.7%, Singapore at 18.3%, and Australia at 16.3%.

Africa is leapfrogging traditional banking entirely. Mobile money systems like M-Pesa in Kenya operate on A2A principles and serve populations that never had a bank card to begin with. A2A is not replacing the old system in Africa — it is the first system for millions of people.

The Americas are catching up. Brazil's Pix is a global success story. In LATAM, digital wallets and A2A systems are responsible for 46% of the region's payments. In the US, FedNow launched in 2023 but adoption is still early — the American consumer's attachment to card rewards programmes is slowing things down.

Will A2A Payment Kill Visa And Mastercard In Europe And Worldwide?
Not kill. But pressure, significantly and permanently.

The Capgemini World Payments Report 2025 projects that A2A instant payments will grow from 16% of all non-cash transaction volumes in 2023 to 22% by 2028, whilst card payments will decline from 57% to 50% during the same period. That is not death. But it is a shrinking empire.

In Europe specifically the pressure is intensifying. The European Payments Initiative launched Wero, a pan-European A2A wallet backed by major European banks, with the explicit goal of reducing dependence on American card networks.

European regulators have made no secret of wanting payment sovereignty, the ability to move money across Europe without it flowing through US-owned infrastructure.

For Visa and Mastercard the real threat is not consumers switching overnight. It is merchants. When a small business can accept payment at 0.2% instead of 2%, the economics are obvious.

As A2A becomes easier and more familiar to consumers, merchant incentives to push it will grow, and with them, the slow erosion of card dominance.

Worldwide the picture is more varied. In markets where cards never took hold, much of Africa, parts of Asia, rural Latin America, A2A has no incumbent to defeat. It simply wins by default.

What Is The Future Of A2A Payments?
The direction is clear. A2A payments are expected to increase from 60 billion transactions in 2024 to 186 billion by 2029, a 209% increase.

But the future is not just more transactions. It is deeper integration into daily financial life:

Variable Recurring Payments (VRPs), allowing businesses to pull regular payments from your account with your permission, replacing direct debits with something smarter and more transparent.

Cross-border A2A, the holy grail. Sending money between countries instantly and cheaply, without SWIFT delays or correspondent bank fees. Still developing, but coming.

Embedded finance, A2A built invisibly into apps, platforms, and services so the payment happens in the background without the user ever thinking about it.

AI and fraud prevention, the biggest challenge for A2A is that payments are instant and irrevocable. Once sent, they cannot easily be recalled. AI is now being built into A2A systems to detect fraud before it happens.

According to Worldline, A2A is rapidly becoming the default payment infrastructure of the digital economy. The question is no longer whether it will grow, it is how fast.
