Pay by Bank for Online Casinos: Open Banking Hits Default

For most of the last decade, the European online casino deposit page has looked the same: Visa, Mastercard, a couple of e-wallets, maybe a local bank transfer hidden behind a “more methods” link. In 2026 that hierarchy is finally breaking. Pay by Bank — the consumer-facing brand for open banking-powered account-to-account (A2A) payments — is moving from a niche option to the default deposit choice for an increasing share of European players.

The shift is not happening because operators woke up one morning and decided to redesign their cashier. It is happening because the underlying economics of card payments in regulated iGaming have continued to deteriorate, while open banking infrastructure has matured to the point where the player experience is finally competitive with cards. For operators who still treat Pay by Bank as an afterthought, the next 12 to 18 months are going to be uncomfortable.

What Pay by Bank actually is

Pay by Bank is the consumer label for instant A2A payments initiated through an open banking PISP (Payment Initiation Service Provider). Under PSD2 in the EU and the FCA’s open banking framework in the UK, banks are required to expose APIs that let licensed third parties initiate a payment directly from a player’s bank account, with strong customer authentication handled inside the player’s own banking app.

From the player’s perspective, the flow is simple:

1. Choose Pay by Bank at the cashier
2. Select their bank from a list
3. Get redirected (or app-switched on mobile) into their banking app
4. Approve the payment with biometrics or a banking PIN
5. Land back on the casino with funds credited

There is no card number to enter, no 3DS challenge to fail, no card on file to expire, and no chargeback right under the card scheme rules. The funds settle in the operator’s bank account in seconds via the underlying instant payment rail — SEPA Instant in the eurozone, Faster Payments in the UK, and increasingly the new pan-European wave of instant rails covered in our real-time payment rails guide.

Why operators are moving now

There are three forces converging that make 2026 the inflection year.

1. Card economics keep getting worse for iGaming

European card schemes have been steadily reclassifying gambling merchants into higher-risk MCCs, and acquirers have been pricing accordingly. Authorisation rates on cross-border card transactions for licensed operators routinely sit below 80%, and on some BIN ranges below 60%. Add the interchange and scheme fees, the 3DS friction tax, the chargeback exposure, and the perpetual issuer-by-issuer optimisation work, and the all-in cost of a successful card deposit has become hard to defend.

Pay by Bank flips the equation. There is no interchange. PISP fees are a flat or tiered fee per transaction rather than a percentage. Authorisation rates on completed Pay by Bank flows regularly clear 95%+. The deposit is final the moment the bank confirms — there is no clearing window, no dispute window, no chargeback. For an operator processing tens of millions of euros in monthly deposits, the swing in unit economics is not marginal.

2. The mobile UX is finally good

The historical knock against Pay by Bank was that the redirect flow felt heavy on mobile. That argument no longer holds. App-switching from a casino’s mobile site or app into the player’s banking app and back has become a one-tap experience on both iOS and Android, with biometric approval that is genuinely faster than typing a 16-digit PAN, expiry, CVV, and then waiting for an SMS OTP.

In our own deployments and in published data from major European PISPs, completion rates on mobile Pay by Bank flows now match or exceed mobile card flows for returning players, and significantly exceed them for first-time deposits where the player has no card on file. The UX gap that protected cards for so long has closed.

3. Regulators are quietly nudging operators away from credit

The UK’s ban on credit card gambling deposits in April 2020 was an early signal. Since then, multiple European regulators — Sweden, Germany, the Netherlands, and most recently several state-level frameworks — have introduced affordability and source-of-funds requirements that are dramatically easier to satisfy with bank-rail data than with card data. Open banking gives the operator a clean, consented view of the account the deposit is coming from, which is exactly the data point modern responsible gambling and AML frameworks want to see.

Operators who lean into Pay by Bank are not just getting cheaper transactions. They are getting compliance posture that holds up to regulator scrutiny, with audit trails the card rails simply cannot produce.

Where Pay by Bank fits in a 2026 cashier strategy

The mistake we see operators make most often is treating Pay by Bank as a single button to add alongside cards. In reality, getting the full benefit requires three coordinated changes to how the cashier works.

Promote it, do not bury it

Default ordering matters. Operators who put Pay by Bank above cards in the method list — and label it clearly with the bank logo the player will be redirected to — see Pay by Bank share jump from low single digits to 30 to 50 percent of European deposits within weeks. The change is almost entirely a function of placement and trust signalling, not promotion.

This is the kind of change that should be A/B tested rather than guessed at. Our piece on the role of A/B testing in improving deposit flows covers the framework we use with operators to validate cashier reordering experiments without burning conversion on the way.

Use it to reduce KYC friction

If you are integrating with a PISP that also offers an AISP (Account Information Service Provider) layer, the same player consent that initiates the payment can pull verified account-holder name, address, and account history. That data feeds directly into KYC, age verification, source-of-funds checks, and affordability assessments — eliminating one of the largest sources of drop-off in regulated markets.

This is where the connection to broader global KYC standards for iGaming payments becomes operational. Pay by Bank with embedded AISP turns KYC from a separate, friction-laden step into a byproduct of the deposit itself.

Plan for withdrawals, not just deposits

The other half of the equation that operators forget is payouts. The same A2A rail that brings money in can send it out, and SEPA Instant and Faster Payments make those payouts genuinely instant — minutes, not the 1 to 5 banking days a card refund takes. For VIP and high-frequency players, instant payout becomes the single most powerful retention lever a cashier has, and it is essentially free once the rails are connected.

The operators who win with Pay by Bank do not just lower their deposit costs. They use the rail to deliver a payout experience that legacy card-centric competitors cannot match. We covered the broader retention case in faster payouts, happier players: why withdrawal speed matters.

What about the rest of Europe?

The picture is uneven by country, and that unevenness matters for routing strategy.

• United Kingdom — Open banking is mature, well-trusted, and Pay by Bank is already a meaningful share of regulated deposits. SCA is bank-side and frictionless.
• Germany — Sofort and giropay legacy users transition cleanly to Pay by Bank. Strong regulator support for A2A in the GlüNeuRStV regime.
• Netherlands — iDEAL is itself effectively a Pay by Bank rail and dominates Dutch online deposits. Operators here often do not need a separate “Pay by Bank” button — iDEAL is the button.
• Nordics — Trustly, Brite, and similar PISPs have been the dominant deposit method for years; this market is already past the transition.
• France, Italy, Spain — Card share is still high, but PISP coverage is now sufficient to make Pay by Bank a credible default. Operators here have the largest opportunity to gain ground in 2026.
• CEE markets — Coverage varies by country and bank. Worth running PISP A/B tests rather than launching everywhere at once.

A serious cashier does not pick one Pay by Bank provider — it routes intelligently between PISPs based on country, bank coverage, success rate, and price. This is where payment orchestration in iGaming stops being a buzzword and starts being table stakes.

How Fluid handles Pay by Bank

The Fluid Cashier treats Pay by Bank not as a single integration but as a category of rails to be orchestrated alongside cards, wallets, and crypto. Operators get:

• Multi-PISP routing across the major European providers, with per-country preferences and automatic failover
• Bank-level success-rate monitoring, so under-performing providers get demoted automatically rather than after a quarterly review
• Embedded AISP for KYC, source-of-funds, and affordability — pulling the data once at deposit time rather than running a separate flow
• Instant-payout configuration on the same rails, with country-specific payout policies for VIP segments
• Native SCA handling so that the player never sees a “your bank declined this” error that was actually a routing or session issue

The bottom line

Pay by Bank is not a payment method to add. It is a structural change in how European online casino deposits will work for the next decade. The operators who reorganise their cashier around it in 2026 will lock in lower processing costs, higher authorisation rates, instant payouts, and cleaner regulatory posture before their competitors do. The operators who keep cards at the top of the deposit list, with Pay by Bank as a tucked-away alternative, will pay for that decision in unit economics quarter after quarter.

Cards are not going away in 2026. But they are no longer the default in Europe — and the cashier UI should stop pretending otherwise.
