Nopan and DIAS Partner to Expand IRIS Commerce Access for International PSPs

Nopan and DIAS announce IRIS Commerce partnership

Nopan announced the partnership with DIAS S.A. on July 1, 2026. DIAS operates Greece’s national payment infrastructure and provides services including the IRIS account-to-account payment ecosystem.

Under the agreement, Nopan will integrate IRIS Commerce into its payment platform, giving payment service providers and merchants based outside Greece a route to offer the method to customers in the Greek market.

The announcement follows Payments360, a DIAS payments conference that brought together participants from the Greek and wider European payments industry.

How IRIS Commerce works

IRIS Commerce allows consumers to pay an online merchant directly from their bank account through their existing banking application. The payment experience is built around account-to-account transfers rather than card credentials.

For consumers, this means they can approve a payment using a familiar bank environment. For merchants and payment service providers, the method adds a domestic account payment option alongside cards and digital wallets.

According to the companies, IRIS Commerce ecommerce transaction volumes increased by more than 70% during 2025 and were approximately 16 times higher than in 2020. The figures were provided in the partnership announcement and reflect the continued adoption of account payments in Greece.

What the partnership changes

The main change is the distribution model.

International payment service providers have traditionally needed direct commercial and technical arrangements before adding a domestic payment method to their checkout offering. Nopan’s integration is intended to provide another access layer between international PSPs, enterprise merchants and IRIS Commerce.

The partnership does not mean that IRIS Commerce has become a domestic payment method outside Greece. Instead, it enables payment companies and merchants located outside the country to offer IRIS Commerce when serving Greek consumers.

This distinction matters for international businesses evaluating local payment coverage. The legal location of the merchant or PSP may be outside Greece, while the payment method remains designed around Greek bank accounts and banking applications.

Why local account payments matter for merchants

Domestic account payment methods can help merchants align checkout options with established consumer behaviour in each market.

A payment option may have strong domestic recognition even when it is less familiar to businesses headquartered elsewhere. Making these methods available through international payment platforms can reduce the integration work required to enter or expand within a local market.

The Nopan–DIAS agreement also reflects a broader European trend: domestic account payment schemes are seeking additional distribution through PSPs, payment platforms and enterprise merchant integrations.

For international merchants, the operational questions will include:

• Whether their PSP supports IRIS Commerce
• Which merchant categories and transaction types are eligible
• How payment confirmation, refunds and reconciliation are handled
• What onboarding and technical requirements apply
• How the method is presented within the Greek checkout experience

Rollout details remain limited

The announcement confirms the partnership and planned platform integration but does not provide a public production launch date.

It also does not specify pricing, merchant onboarding requirements, settlement arrangements or a complete technical implementation schedule. Payment service providers and merchants will therefore need to confirm commercial availability directly with the relevant integration provider.

For now, the announcement should be treated as an expansion of access infrastructure rather than confirmation that every international merchant can activate IRIS Commerce immediately.
