What are real-time payments, and how do they move money in seconds?
In a growing number of countries, money can leave one bank account and be usable in another a few seconds later, at any hour. Here is how these systems work, where they came from and why an instant payment needs extra care.
The short answer
Real-time payments, also called fast or instant payments, move money between bank accounts in seconds, around the clock, with the funds final and usable straight away. Examples include UK Faster Payments (2008), India's UPI (2016), Brazil's Pix (2020) and the U.S. FedNow Service (2023).
Key takeaways
- The BIS describes fast payment systems as infrastructure that delivers payment messages and final funds in real time or near real time, 24 hours a day, every day1.
- More than 120 fast payment systems were operating worldwide by 20241, from the UK's Faster Payments to India's UPI and Brazil's Pix.
- Instant payments can be very cheap: Pix is free for individuals4, and EU rules stop banks charging more for instant euro transfers than for ordinary ones8.
- Speed cuts both ways. FedNow payments are final and irrevocable6, so a payment sent to a scammer is hard to claw back.
- Always check who you are paying before you send, especially if someone is rushing you.
What counts as a real-time payment?
A real-time payment is a transfer from one account to another where the money arrives, and can be spent, within seconds. The Bank for International Settlements (BIS) defines retail fast payment systems as infrastructures that transmit payment messages and make final funds available between individuals, businesses and governments in real time or near real time, on a 24/7 basis1.
Three words in that definition do the work. Final means the payment cannot be undone by the system once it is complete. Real time means seconds, not the next business day. And 24/7 means weekends and public holidays too. A card payment, by contrast, is approved in seconds but settled between banks later, as our explainer on how card payments work shows.
How does an instant payment get from your bank to theirs?
You never connect to the payment system yourself. Your bank or payment app does. When you press send, your bank checks the request and passes it to the national fast payment system, which routes it to the recipient's bank. That bank credits the recipient and confirms, all within seconds.

The key difference from older transfers is settlement. In FedNow, each payment settles individually in the participating bank's master account at the Federal Reserve, which means in central bank money, and all payments are complete, final and irrevocable6.
What happens when you press send
- 1
You enter the payee's details
An account number, phone number, email or other alias, depending on the country and app.
- 2
Your bank runs checks
For example fraud and sanctions screening. Under EU rules, banks must also offer a free check that the name matches the account before you pay8.
- 3
The system routes and settles
The national system passes the payment to the recipient's bank and settles it between the two banks.
- 4
The recipient is credited
Their bank credits the account and both sides get a confirmation, typically within seconds.
Which countries have real-time payment systems?
Many countries now have one. According to a BIS working paper, there were over 120 fast payment systems in operation around the world as of 20241. The four below show how differently they can be built and run.

Four national systems compared
| System | Launched | Run by | A telling number |
|---|---|---|---|
| Faster Payments (UK) | 20082 | Pay.UK | 5.55 billion payments worth £4.84 trillion in 20252 |
| UPI (India) | 11 April 20163 | National Payments Corporation of India, overseen by the Reserve Bank of India | About 22.6 billion transactions in March 2026 (2,264 crore)3 |
| Pix (Brazil) | 16 November 202010 | Banco Central do Brasil | Used by 67% of Brazilian adults by February 20224 |
| FedNow (U.S.) | July 20, 20235 | Federal Reserve | 1,600 participating financial institutions in 20257 |
Scale varies enormously. India's government says UPI handled 85% of the country's digital payments in fiscal year 2025-26 and about 49% of global real-time payment volume in 20253. FedNow started with 35 banks and credit unions plus the U.S. Treasury's Bureau of the Fiscal Service in 20235, and participation is voluntary, so not every U.S. bank offers it yet.
Europe took a legal route. The EU's Instant Payments Regulation, adopted on 13 March 2024, required payment providers in the euro area to be able to receive instant euro transfers from 9 January 2025 and to send them from 9 October 2025, with later deadlines for countries outside the euro area8.
Why are instant payments often so cheap?
Some systems were designed with low prices in mind. Brazil's central bank made Pix transfers free of charge for individuals; the BIS reported an average cost to merchants of 0.22% of the payment, against 2.2% for credit cards in Brazil, and a fee to payment providers of BRL 0.01 per 10 transactions4.
The EU went further and wrote price parity into law: any charge for sending or receiving an instant euro transfer cannot be higher than what the same provider charges for an ordinary credit transfer8.
Worked example
Pix versus a credit card on a R$200 sale
Using the BIS averages, a merchant would pay about R$0.44 on a R$200 Pix payment (0.22%) and about R$4.40 on the same sale by credit card (2.2%)4. These are illustrative averages; real fees depend on the merchant's contract.
What are the risks of sending money instantly?
The feature that makes instant payments useful also makes them risky. Once a FedNow payment is complete it is final and irrevocable6, and fast payment systems in general are built to deliver final funds1. If you send money to the wrong account, or to a fraudster, you cannot simply cancel it. Any chance of getting it back may depend on the banks involved and on local consumer rules.
That makes pressure a red flag: a message or call that claims to be from your bank, a delivery firm or a tax office and insists you move money now. Rules are catching up. In the UK, victims of scams paid by Faster Payments or CHAPS on or after 7 October 2024 can claim up to £85,000 back from their payment firm, within 13 months of paying11. EU banks must now offer a free check that the payee's name matches the account before you confirm an instant euro payment8. FedNow lets banks set their own transaction limits below the network maximum, with a default of $100,0006.
Risk warning
Pause before you press send
Treat an instant payment like handing over cash. Be deeply suspicious of anyone who asks you to move money to a "safe account". If you are being rushed, stop and call the organisation back on a number you find yourself. If you have already paid a scammer, tell your bank immediately.
What mistakes do beginners make with instant payments?
Common beginner mistakes
Assuming you can cancel
Instant usually means final. Double-check the amount and the payee before confirming, not after.
Ignoring a name-check warning
If your app says the name does not match the account, stop and confirm the details through a separate channel.
Paying strangers for goods up front
An instant transfer is final6. If the goods never arrive, there may be no easy way to get your money back.
Expecting every bank to support it
In the U.S., FedNow participation is voluntary, so your bank may not offer instant transfers yet5.
Frequently asked questions
Is there a limit on how much I can send instantly?
Is a real-time payment the same as a digital currency?
No. Real-time payment systems move ordinary bank money between accounts; in FedNow, banks settle in their accounts at the Federal Reserve6. A central bank digital currency would be a new form of money. See our CBDC explainer.
Can I send an instant payment to another country?
The systems in this guide are national systems for payments inside one country or currency area. Sending money abroad is a different journey, which our explainer on cross-border payments covers.
Does instant mean the payment is free?
Can I cancel an instant payment after sending it?
Generally no. In FedNow, completed payments are final and irrevocable6. Contact your bank straight away if you made a mistake or were tricked, but do not count on a reversal.
The bottom line
Real-time payments turn bank transfers into something closer to handing over cash: fast, available around the clock and final. That is a genuine upgrade for paying friends, bills and small businesses, but it shifts the burden of care onto the sender. Check the payee every time, and never let anyone rush you into an instant transfer.
