Wero Explained: EPI's Pan-European A2A Payment System vs Visa and Mastercard (2026)

TL;DR

In summer 2024 the European Payments Initiative (EPI) launched Wero, a pan-European A2A payment system built on top of SEPA Instant. By the start of 2026 it had around 53 million users across Germany, France, Belgium and Luxembourg. The Netherlands will follow once the iDEAL to Wero migration completes by 2027. Wero is the most ambitious attempt in over a decade to build a European alternative to Visa and Mastercard, and unlike the previous tries, this one is actually shipping. The story has four moving parts:

✓ 16 European banks bet hundreds of millions of euros on building a shared payment system instead of competing on payments
✓ EPI did not start from scratch. It acquired the established national winners: Germany's Giropay was retired, France's Paylib was migrated, Belgian / Luxembourgish Payconiq and Dutch iDEAL were bought outright
✓ Wero rolls out in phases: P2P in 2024, e-commerce in Germany from late 2025, e-commerce in France and Belgium across 2026, in-store POS in preparation, iDEAL migration to be completed by 2027
✓ On 2 February 2026 EPI signed a memorandum with the EuroPA Alliance (Bancomat, Bizum, SIBS-MB Way, Vipps MobilePay). The plan is a central interoperability hub that lets the local A2A systems exchange payments while keeping their own brands. Cross-border P2P in 2026, e-commerce and POS in 2027

Why this attempt and not the previous five

EPI did not begin in 2024. EPI Interim Company was incorporated in Brussels in July 2020 with around 31 banks behind it. The original ambition was much bigger: a full pan-European card scheme plus wallet that would compete head-on with Visa and Mastercard at the merchant terminal as well as online. Then reality hit. A new card scheme is hugely capital intensive, requires merchant acceptance everywhere, and depends on coordination between dozens of supervisors. In March 2022 several Spanish, Polish and Portuguese banks pulled out and EPI's original scope collapsed. The remaining 16 shareholders pivoted. The card-scheme idea was dropped. The new scope was a digital A2A wallet only, riding on SEPA Instant rails that the European Central Bank and the European Commission had been pushing into production for years. That pivot is the reason Wero ships and EPI 1.0 did not.

SEPA Instant became a real backbone

The Single Euro Payments Area Instant Credit Transfer scheme (SCT Inst) reached critical mass between 2019 and 2024. Almost every euro-area bank can now send and receive 10-second transfers around the clock. The Instant Payments Regulation (Regulation (EU) 2024/886) makes those transfers mandatory and forces them to cost no more than a standard credit transfer. Without that backbone, Wero would have no rails to ride on. With it, Wero is essentially a user-experience and brand layer on top of public infrastructure.

The mobile payment layer is being prised open

PSD3 and the Payment Services Regulation oblige device manufacturers to give front-end providers fair, reasonable and non-discriminatory access to the data required to execute payments, in practice the NFC and secure-element interfaces on phones. Apple Pay's NFC monopoly is being unwound. Wero is positioned to plug straight into that opening once the rules apply (see our PSD3 article for the timeline).

Political will hardened

Brussels and Frankfurt have spent the past three years framing the dependence on US payment networks as a strategic vulnerability comparable to energy dependence. The digital euro project, the Instant Payments Regulation and the open mobile payment layer all point in the same direction. Wero sits in that political slipstream rather than swimming against it.

The acquisition spree: Giropay, Paylib, Payconiq, iDEAL

Wero's user base did not appear from nothing. EPI absorbed four established national systems, one by one, and converted their installed bases into Wero accounts. This is the most aggressive consolidation in European payments in a decade.

Read in sequence, these four deals tell a strategic story: rather than launch a new brand into a fragmented market and hope to win share organically, EPI bought the share. Wero starts day one with the bank distribution and the merchant footprint of four national champions.

Giropay (Germany), retired

Giropay was the German banking sector's online-payment brand, run by Paydirekt. It never reached critical mass at the merchant side. In 2023 the German banks decided to wind it down rather than continue investing, with the formal shutdown completed in 2024. Customers were not migrated to Wero one-for-one (Wero is account-app-based, Giropay was browser-based), but the budgets, the brand decisions and the banking governance attention all rolled into Wero.

Paylib (France), migrated into Wero

Paylib was the joint mobile-payment app of the major French banks (BNP Paribas, Crédit Agricole, BPCE, Société Générale and others), launched in 2013. It was the closest French analogue to BLIK in terms of bank consortium structure. From 2024 onward Paylib functionality was progressively migrated into the Wero app, with Paylib effectively retired by late 2024.

Payconiq (Belgium and Luxembourg), acquired

Payconiq International was the joint Belgian / Luxembourgish bank-driven payment system, the dominant local QR-code wallet. EPI acquired Payconiq in 2023 and is migrating its user base to Wero. The full Luxembourg transition is planned for 2026.

iDEAL (Netherlands), acquired

iDEAL is the most successful of the lot, with around 70% share of Dutch e-commerce payments. EPI's 2023 acquisition of iDEAL was the biggest single deal in European payments in years and arguably the moment Wero became inevitable rather than aspirational. The full migration of iDEAL traffic into Wero infrastructure is scheduled to complete by 2027.

Architecture: A2A on top of SEPA Instant

Wero is not a new payment network in the Visa or Mastercard sense. It is a user-experience and orchestration layer that runs on top of SEPA Instant. Every Wero transaction moves real money between accounts at participating banks via the standard SEPA Instant rail. The transaction settles in seconds and is final on completion.

Issuer side

The user's bank embeds Wero functionality directly inside its mobile banking app (Sparkasse, ING, BNP, KBC, etc.). The bank handles authentication (SCA), authorisation, and the actual SEPA Instant outgoing transfer.

Acquirer side

Merchants integrate with Wero via standardised APIs, in practice through their existing acquirer (Worldline, Nexi, Adyen and similar). The acquirer relays the payment request, Wero matches it to the customer's bank, and the bank executes the SEPA Instant transfer to the merchant's account.

Wero's role in the middle

EPI Company SE operates the central infrastructure: the request-to-pay messaging layer, the recipient lookup that maps phone numbers and email addresses to bank accounts, the fraud-monitoring layer, and the brand and UX standards every issuer bank has to follow. None of the money flows through Wero. It is messaging plus consent plus brand, exactly the BLIK pattern, exactly the Bizum pattern, just at pan-European scale.

Important nuance:

This is why the comparison with Visa and Mastercard is real but not symmetric. Visa and Mastercard are settlement networks (they run scheme rails, interchange, dispute machinery). Wero is a UX and routing layer over a public settlement network (SEPA Instant) that the central banks already operate. Wero is therefore much cheaper to run than a card scheme, but it inherits the limitations of SEPA Instant (euro only, EU and EEA only, single-currency settlement).

Roadmap 2024 to 2027

Wero's product rollout is sequenced deliberately. Each phase adds a new payment context and a new merchant category.

Phase	Date	Country	Channel
P2P launch	Jul 2024	Germany	Person-to-person, in-app
P2P launch	Sep 2024	France, Belgium	Person-to-person, in-app
Paylib retirement	End 2024	France	Legacy users migrated
E-commerce live	Q4 2025	Germany	Online checkout
E-commerce rollout	2026	France, Belgium	Online checkout
EuroPA memorandum	Feb 2026	EU + Norway	Interoperability hub framework
Payconiq migration	2026	Luxembourg	User base migrated to Wero
In-store POS	Late 2026 to 2027	DE, FR, BE	Tap-to-pay, QR at till
iDEAL migration complete	2027	Netherlands	Full transition into Wero rails
Cross-border e-commerce + POS	2027	EuroPA + EPI	Pan-European interoperability

Dates after 2025 are EPI's stated plan; actual delivery slipped in earlier EPI phases and could slip again. Watch for milestone announcements rather than treating the roadmap as fixed.

Wero vs Visa and Mastercard

Wero is not trying to replace cards everywhere. It is trying to replace cards in the specific contexts where A2A is structurally cheaper and faster: domestic e-commerce, P2P transfers, and in-store payments in Europe. Cross-border tourism payments, global e-commerce and credit-card-driven travel will remain Visa and Mastercard territory for years.

The economics argument

Card payments carry interchange (typically 0.2% for debit, 0.3% for credit on EU cross-border, often higher domestically) plus scheme fees plus acquirer markup. Total merchant cost is regularly 1.0% to 2.5% of transaction value. A SEPA Instant transfer costs the merchant the equivalent of a flat fee under the Instant Payments Regulation, in practice a fraction of a euro. For high-ticket items the merchant saves real money. For low-ticket items the absolute saving is small but the percentage saving is significant.

The speed argument

SEPA Instant settles funds in the merchant's account in seconds. Card payments settle T+1 or T+2 (with deferred net settlement). For cash-flow-tight merchants this matters.

The control argument

Every card transaction routes through US-headquartered networks. European regulators, central banks and increasingly customers view this as a strategic vulnerability. Wero keeps the data, the rails and the supervisory authority inside Europe.

What Wero does not solve

Chargebacks, dispute resolution and consumer protection in cards are mature; in A2A they are still being built. Cards are accepted globally; Wero is not. Cards support pre-authorisation (hold X, capture Y later) natively; A2A systems including Wero typically do not. Cards underpin most premium loyalty and rewards programmes; A2A does not have an equivalent revenue mechanism for that.

Wero and the local heroes

Wero is not the only European A2A system in the field. Bizum dominates Spain (over 30 million users), MB Way dominates Portugal, Bancomat Pay covers Italy, Vipps MobilePay runs the Nordics, BLIK runs Poland, DIAS runs Greece. Each of these systems is locally dominant and was historically unable to operate cross-border.

EuroPA Alliance, March 2025

Three of those systems (Bancomat, Bizum and MB Way) founded the EuroPA Alliance in November 2024. Vipps MobilePay, BLIK and Greek DIAS joined later, bringing the membership to six. The alliance has been operationally live since March 2025. In its first year EuroPA processed roughly 6 million euros of cross-border transfers without any marketing campaign, which is small in absolute terms but signals real underlying demand.

The 2 February 2026 memorandum

On 2 February 2026 four EuroPA members (Bancomat, Bizum, SIBS-MB Way, Vipps MobilePay) and EPI signed a memorandum on the interoperability of pan-European payment solutions. The plan is not a brand merger. The plan is a central interoperability hub: a technical layer that lets the individual systems exchange payments while keeping their own brands, their own apps and their own bank relationships. Cross-border P2P should ship in 2026; cross-border e-commerce and POS in 2027. Combined footprint: around 130 million users across 13 countries and roughly 72% of the EU plus Norway.

The brand question

A reasonable question: if Bizum stays Bizum and BLIK stays BLIK, what does Wero gain from interoperability? The answer is reach. A French Wero user can pay at a Spanish merchant whose acquirer accepts Bizum, because the underlying hub routes the transaction. The brand the customer sees is their own home brand. From the user's point of view the European A2A network becomes seamless without any one brand having to win.

The Polish perspective: BLIK out of the February memo

BLIK is a member of the EuroPA Alliance, but it is not among the signatories of the 2 February 2026 memorandum. The four signatories on the EuroPA side were Bancomat, Bizum, SIBS-MB Way and Vipps MobilePay. Poland is therefore, for now, outside the first wave of pan-European interoperability.

Why this matters

If the rollout goes to plan, by 2027 a Spanish Bizum user will be able to pay at a German merchant who accepts Wero, a French Wero user at a Portuguese MB Way merchant, and so on. A Polish BLIK user is not in that loop yet. Polish e-commerce flows abroad would still need a card or a manual SEPA transfer.

Why BLIK may have hesitated

We covered this in our BLIK article. PSP's strategic priorities through 2024 to 2026 were the Slovak launch, the Romanian authorisation, the Mastercard partnership for BLIK Contactless, and the BNPL product. Joining a heavy interoperability framework while in mid-expansion to two new markets is a different kind of commitment, and EuroPA also has its own internal coordination cost. The initiative is open: BLIK can join in a later phase, and Mastercard as a PSP shareholder may push in either direction.

What Polish fintechs should do about it

Build for both worlds. For domestic flows BLIK is and will remain the dominant Polish A2A rail. For pan-European flows, expect a hub-and-spoke model where merchants accept Wero (or whatever brand the local hub uses) and BLIK users either get bridged in via the hub or get routed through a card fallback. EMI applicants serving cross-border audiences should plan for both rails simultaneously.

What it means for fintechs, merchants and acquirers

Wero changes the planning horizon for several distinct audiences:

For merchants

Wero in checkout is a real cost-saving option versus cards for domestic flows, especially for high-ticket items, subscriptions and digital goods. The acceptance UX is essentially the BLIK or Bizum experience: phone, confirm, done. Conversion data from Germany and France through 2026 will tell us whether Wero matches cards on completion rates. Watch the early numbers from large German retailers.

For acquirers

Wero is not optional for serious EU acquirers. By end-2027 a Worldline, Nexi, Adyen or SumUp without Wero acceptance will be missing a major slice of the domestic European e-commerce and POS market. Integration work is non-trivial but the API model is similar to BLIK and Bizum, so there is reusable engineering.

For EMT issuers and stablecoin firms

Wero validates the broader thesis that euro-denominated A2A on public rails is a serious threat to card networks. That is a tailwind for EUR stablecoins and tokenised deposits aimed at the same use case. It is also a headwind: if domestic and pan-European A2A becomes cheap and ubiquitous, the incremental utility of an EMT for payment use cases shrinks.

For card issuers

Cards do not go away, but the high-margin domestic e-commerce flows that have funded European card programmes for two decades are starting to migrate. Premium cards with rewards and travel benefits will survive longer than vanilla debit. Vanilla debit is the segment most exposed to Wero.

For Polish fintech firms

Build BLIK first, but design the integration so that future Wero or EuroPA routing slots in without re-architecting. The hub model is the destination state.

What to watch in 2026 and 2027

Several measurable signals will tell us whether Wero is on its trajectory or quietly missing milestones:

✓ Active monthly user count, by country. EPI quotes 53 million at start of 2026; the slope through 2026 matters more than the absolute number
✓ Wero merchant acceptance count in Germany by end of 2026, and the slope into France and Belgium
✓ Wero share of German e-commerce. The honest target is to beat Giropay's all-time peak (single-digit percent) by end of 2026 and to start eating into card share by end of 2027
✓ Pace of iDEAL migration in the Netherlands, with the 2027 deadline as the public commitment
✓ First production cross-border transactions under the EuroPA + EPI hub framework, ideally in late 2026
✓ Any new EPI shareholders or, conversely, any pull-outs. The 2022 EPI 1.0 collapse showed how quickly bank consortia can unravel under pressure
✓ Apple's response to PSD3 NFC opening and how Wero positions on iPhones once the rules apply
✓ BLIK's relationship with EPI: a later joining, or a continued parallel existence

Closing

Wero is the most credible attempt in over a decade to build a European alternative to the global card networks. It is not because Wero is technically novel: BLIK has been doing essentially the same architecture in Poland since 2015, Bizum in Spain since 2016, Swish in Sweden since 2012. Wero is credible because EPI bought the four largest national A2A footprints rather than trying to win them organically, and because SEPA Instant, the Instant Payments Regulation and PSD3 give it a structural tailwind the previous attempts did not have. The story for 2026 and 2027 is not whether Wero exists (it does and it is shipping) but whether it scales fast enough to matter before the political and regulatory window closes. Visa and Mastercard are not standing still, and Apple Pay and Google Pay will keep adapting as the NFC monopoly is unwound. The next 18 months are the moment Wero either becomes the European payment fabric of the late 2020s or settles into a useful but secondary role behind cards.

If you are designing a European payment product, A2A is no longer a curiosity. Card-first design is starting to look like designing for a single rail in a multi-rail world.
