Digital payments

Its role in the system

A layer of convenience on top of banks and card networks: companies that let you pay with one tap, start accepting payment on a website in minutes, send money to a phone number or embed payments in any app. For the most part they do not build new rails — they use the old ones in new ways: cards, bank accounts and instant transfers.

Functions

1. Accepting online payments (PSPs, payment providers) — 🌍 Stripe, Adyen and PayPal connect online shops and platforms to cards, wallets and local payment methods through one integration, and take on anti-fraud and settlement with the merchant.
2. Digital wallets — Apple Pay and Google Pay replace the card number with a token in the phone; PayPal stores the payer's details or its own balance so they need not be entered every time.
3. Instant account-to-account transfers — payment without a card, by QR code or phone number: 🇧🇷 Pix, 🇮🇳 UPI, 🇵🇱 BLIK, 🇪🇺 Wero (from 2026 absorbing the Dutch iDEAL under the brand "iDEAL | Wero").
4. Open banking — with the client's consent a third-party service can see their accounts through an API or initiate a payment from them (🇪🇺 PSD2, 🇬🇧 Open Banking).
5. Embedded finance (BaaS) — non-financial companies (marketplaces, ride-hailing, accounting software) offer accounts, cards or instalments inside their own product, relying on a partner bank's licence.
6. A new generation of international transfers — 🌍 Wise and similar fintechs hold money locally in each currency and transfer through mirrored accounts, bypassing the long correspondent chain.

What makes it special

• How it earns, and why it is not a bank: income comes from a percentage or a flat charge on every transaction, the exchange rate margin, interest on client balances and fees for extra services; the business scales, but the margin is thin, so volume and the share of successful payments decide everything. It works under a separate licence: a payment institution or an electronic money institution does not lend out client money and must keep it segregated (safeguarding). 🇪🇺 the rules are set by PSD2 and the e-money directive.
• Security: 🇪🇺 strong customer authentication (SCA) under PSD2; since October 2025 payment providers in the euro area must check free of charge that the beneficiary's name matches the IBAN. The new wave of fraud is talking a person into sending the money themselves — which is why 🇪🇺 PSD3/PSR (political agreement in November 2025, application expected from 2027–2028) will tighten providers' liability, including a duty to refund fraud where someone impersonates the bank.
• Who regulates: central banks and financial regulators (🇪🇺 national authorities under PSD2, 🇬🇧 the FCA, 🇺🇸 state regulators and the CFPB, whose powers have been substantially narrowed since 2025). In embedded finance responsibility is blurred between the fintech, the intermediary and the bank — and that is exactly where things go wrong.
• The state as a competitor: central banks increasingly build instant payments themselves (🇧🇷 Pix, 🇺🇸 FedNow, 🇪🇺 the EU rule making instant euro transfers compulsory), reducing dependence on card networks and private wallets.
• 🇨🇳 China: the country that skipped cards: retail payments went straight to QR codes inside the Alipay and WeChat Pay apps — the customer pays from a wallet balance or a linked account, and the merchant needs a printed code rather than a terminal, so accepting payments is cheap even for a street vendor. Since 30 June 2018 payments from non-bank wallets to banks must pass through the state clearing platform NetsUnion: the central bank sees every transaction, and the wallets lost their direct deals with banks. The convenience is private; the pipe underneath it is public.
• 🇮🇳 India: the rail was built by the state: the UPI interface belongs not to a company but to the non-profit NPCI, set up by the banks with the central bank behind it, and every bank and app (Google Pay, PhonePe, Paytm) plugs into it as an equal participant — which is why a payment by phone number or QR code works between any of them. The scale is enormous: 23.2 billion UPI transactions in May 2026 alone. For people it is free: a ban on charging merchants applied from January 2020, and only in August 2026 did parliament allow the government to introduce small fees, aimed mainly at large chains.

Why it matters

Digital payments have become the main way millions of people and businesses settle up. When a payment provider or a fintech intermediary falls over, clients' money can be stuck for weeks — even though formally it is "in a bank".

• Anti-Money LaunderingDigital payments firms fall under Anti-Money Laundering, and quick onboarding makes them attractive to money mules.
• Banking & Credit InstitutionsBanking & Credit Institutions give Digital payments the licence, the accounts and the access to the rails; in return, fintechs take over the customer interface.
• Card networksDigital payments mostly ride on Card networks: wallets and online checkouts settle as card transactions, and the payment service provider often acts as the acquirer that plugs the merchant into the network.
• Corporations & Corporate FinanceDigital payments decide how much e-commerce inside Corporations & Corporate Finance actually collects, and treasuries use open banking to manage accounts across several banks.
• Credit InformationOpen banking wired Digital payments into Credit Information: with the customer's consent an outside service can see the flows through an account, and that becomes an alternative source for assessing creditworthiness.
• Crypto / CBDCFor Digital payments, Crypto / CBDC is simply another payment method: the provider takes on the conversion and the merchant still receives ordinary currency in the account.
• Households & IndividualsWallets, instant transfers by phone number and QR codes make payments by Households & Individuals immediate; Digital payments is also where fraudsters push people into sending money voluntarily.
• Interbank systemsDigital payments rest on Interbank systems: instant account-to-account transfers are carried by central bank rails such as TIPS in the euro area and FedNow in the United States.
• International transfersDigital payments bypass the long correspondent chain behind International transfers: fintechs hold money locally in each currency and shift it between mirrored accounts, competing on price and speed.
• Monetary PolicyDigital payments compete with central banks too: Monetary Policy runs its own instant rails (Pix since 2020, FedNow since 2023) and in the EU obliges banks to send instant euro transfers, while the policy rate sets what a provider earns on the float it holds.
• Regulation & SupervisionDigital payments firms need a licence from Regulation & Supervision, must safeguard client money and must meet consumer protection rules.
• Retail accessDigital payments fund and withdraw money from the brokerage and investing apps of Retail access, by card, open banking and Apple Pay or Google Pay wallets.
• Technology & InfrastructureDigital payments are assembled out of Technology & Infrastructure: open banking APIs, cloud platforms and machine-learning fraud detection.
