Real-Time Payments
Also known as: RTP, instant payments, FedNow, Faster Payments, instant bank transfer
Real-time payments (RTP) are bank-to-bank payment transfers that settle instantly (within seconds), are available 24/7/365, and are irrevocable once sent.
In the US, the two RTP networks are The Clearing House's RTP network (launched 2017) and the Federal Reserve's FedNow (launched July 2023). Internationally, real-time payment systems include UK Faster Payments, India's UPI, Brazil's PIX, Australia's NPP (New Payments Platform), and the EU's SEPA Instant Credit Transfer. Real-time payments are transforming consumer and business payments by enabling immediate fund availability rather than the day-or-more delay of traditional bank transfers.
Real-Time Payments, explained at three levels
At home
Real-time payments move money from one bank account to another in seconds, around the clock. When you pay someone via Zelle and see the money move almost instantly, real-time payments are the infrastructure that makes that possible for bank account transfers. Unlike a regular bank transfer (ACH) that takes 1-3 days, real-time payments mean the recipient's account is funded immediately and the funds are available right away.
At work
Real-time payments matter for businesses in two key scenarios: paying employees or suppliers instantly (payroll emergencies, contractor pay-on-delivery, urgent vendor payments) and receiving payments instantly (no waiting for customer payment to settle before shipping goods or starting services). The always-on nature (24/7, including weekends and holidays) also matters: a payment made at 11pm Sunday on a traditional bank system might not settle until Tuesday morning; real-time payments settle immediately regardless of time.
At home
Zelle is a network run by Early Warning Services, a company owned by large US banks. When you send money, Zelle passes a message between the two banks and the recipient's bank credits their account within minutes; the banks settle the actual funds between themselves afterwards. Venmo and Cash App instead move balances inside their own ledgers. Because Zelle payments are designed to be final, the sender cannot reverse one the way a card payment can be disputed, which is why scammers favour it.
At work
FedNow vs. RTP (The Clearing House): both are US real-time payment networks operating on ISO 20022 messaging standards. RTP (TCH) has been live since 2017, is owned by a consortium of large US banks, and raised its per-transaction limit to $10M in 2025. FedNow launched in 2023 with a $500K limit, raised to $10M in late 2025, is operated by the Federal Reserve, and is designed to be more accessible for smaller financial institutions. The two networks do not connect directly, so a bank must join both to reach every participant.
At home
Request for Payment (RfP) is a real-time payment feature that enables electronic invoicing via the payment rails: a payee sends a structured payment request to the payer through their bank, the payer reviews the details and approves payment, and money moves instantly. RfP eliminates the invoice-to-payment friction of traditional invoicing by combining invoice delivery and payment authorization in a single bank-to-bank flow. This is particularly impactful for B2B payments where invoice-to-cash cycles are a significant working capital concern.
At work
Real-time payment system design at scale involves: irrevocability (settled payments cannot be reversed by the sending institution: fraud response must occur pre-authorization or through separate reclaim processes); liquidity management (banks must maintain prefunded liquidity positions in real-time settlement accounts); ISO 20022 data richness (full remittance information travels with the payment, enabling automated reconciliation); and 24/7 operations (banks must staff systems and fraud monitoring continuously, a significant operational model change from batch-era banking).
Real-world examples
At home
Lena, a freelance consultant, completed an urgent project on a Friday evening. Her client, instead of waiting until Monday to initiate an ACH payment that would arrive mid-week, sent payment via Zelle at 9pm Friday. The funds appeared in her account within minutes. She was able to pay her own subcontractor the same evening from the received funds, a payment chain that previously would have involved a week of waiting.
At work
Jerome ran a moving company that required payment upon delivery. He switched from check acceptance (risk of bounced checks) to Zelle payments on delivery. Customers scanned his business's Zelle QR code and payment arrived in his business account instantly, confirmed before movers left. Bad debt from bounced checks dropped to zero, and customer payment friction was minimal.
Common confusions
- Many people assume that payment apps like Venmo and PayPal are real-time payments in the bank transfer sense — Venmo, PayPal, and CashApp maintain their own internal account balances: when you send money within these apps, they are moving numbers within their own ledger, not bank accounts. The transfer appears instant because it is internal. Moving that balance to your actual bank account takes 1-3 business days for standard transfers or charges an instant transfer fee. Bank-based real-time payments (Zelle, FedNow, RTP) move funds directly between bank accounts without an intermediary wallet.
- Some businesses assume real-time payments will eventually replace ACH entirely — RTP and ACH serve different purposes and will likely coexist. ACH has significant cost advantages for high-volume, non-urgent, bulk payments (payroll, regular supplier payments, subscription billing). Real-time payments carry a premium per transaction and are most valuable for time-sensitive or irrevocability-required scenarios. The economics of payroll processing for 10,000 employees via real-time payments vs. ACH strongly favour ACH for the scheduled, predictable batch scenario. RTP displaces ACH where speed or 24/7 availability has business value.
For analysts
When a client experiences significant working capital inefficiency from delayed payment settlement (waiting 2-5 days for customer payments to clear before initiating fulfillment), a real-time payment collection strategy is worth quantifying. The business case: reduced days-sales-outstanding (DSO), lower credit risk (payment confirmed before goods ship), and lower banking float cost. For service businesses with high-value transactions, RTP-enabled same-day customer payment can meaningfully improve cash flow, particularly for small-to-medium businesses with thin working capital buffers.
History & origin
The UK launched Faster Payments in 2008 (one of the world's first real-time payment systems) enabling near-instant bank-to-bank transfers for UK domestic payments. India's UPI (Unified Payments Interface, launched 2016) became arguably the most impactful real-time payment system globally by volume, processing billions of transactions monthly at zero cost for consumers, dramatically accelerating financial inclusion and digital payment adoption. Brazil's PIX (launched November 2020) achieved mass adoption within months, with 70%+ of the adult population registered. The US lagged significantly: The Clearing House launched RTP in 2017 but adoption was limited due to uneven bank participation. The Federal Reserve's FedNow (July 2023) addressed participation gaps by creating a second rail accessible to smaller banks and credit unions. ISO 20022 messaging standards underpin most modern real-time payment systems globally.
