Major retail banks (Millennium bcp, Santander, Novo Banco) offer complete remote onboarding via digital keys (Chave Móvel Digital) or biometric video verification for residents. Electronic Money Institutions (EMIs) like Revolut — operating under a European banking license with Lithuanian-backed IBANs usable for direct debits in Portugal — and other digital-first fintechs serve as primary day-to-day transaction tools, offering instant SEPA-enabled account setup via smartphone app. MB Way, the national interbank mobile payment network operated by SIBS, maps a user's mobile number to their bank card, enabling instant peer-to-peer transfers, cardless ATM withdrawals, and QR-code POS payments; 2026 integration protocols extend interoperability to Spain's Bizum and Italy's BANCOMAT Pay.
