SIBS is the Portuguese interbank processor behind the Multibanco (MB) network and the MB WAY mobile payment app used by millions of Portuguese. Through the EuroPA alliance, MB WAY interoperates with Spain’s Bizum, Italy’s Bancomat and — crucially for the corridor — Norway’s Vipps MobilePay, building instant cross-border mobile payments between Portugal and the Nordics.
SIBS — the Sociedade Interbancária de Serviços — runs the rails of Portuguese retail payments, from the ubiquitous Multibanco (MB) network to MB WAY, the mobile app that millions of Portuguese use for instant transfers, purchases and ATM access. It is one of Europe’s most advanced national payment schemes.
SIBS-MB WAY is a founding member of EuroPA, the alliance of European domestic payment schemes that already links Spain’s Bizum and Italy’s Bancomat and has expanded to include Norway’s Vipps MobilePay. Live since March 2025 and reinforced by a February 2026 Memorandum of Understanding with EPI, the cooperation is building seamless cross-border mobile payments across roughly thirteen European countries and around 130 million users, with full interoperability targeted for 2027.
For the Portugal–Nordics corridor, EuroPA is foundational plumbing: it lets a Portuguese MB WAY user and a Norwegian Vipps MobilePay user pay each other by phone number, without cards or a US card network in the middle. As trade, tourism and remote work between Portugal and the Nordics grow, sovereign European payment interoperability turns a fragmented map into a single market — and puts a Portuguese champion at its centre.
In February 2026, SIBS-MB WAY, Bancomat, Bizum and Vipps MobilePay signed a Memorandum of Understanding with EPI Company to accelerate sovereign, pan-European cross-border payments, building on the EuroPA network that has operated since March 2025.
