Licensed digital operators — Revolut (Spanish branch IBAN starting 'ES'), N26, and domestic digital anchors Openbank (Santander) and Imagin (CaixaBank) — capture most mobile-first users, offering zero-fee checking accounts, fee-free FX, and instant push-notification accounting. Bizum, the instant P2P mobile payment rail built into virtually all Spanish banking apps, expanded cross-border in 2026 via the EuroPA Alliance/European Payments Initiative to 13 European countries (interoperating with Portugal's MB WAY and Norway's Vipps MobilePay); May 2026 saw native NFC contactless in-store payments launch, bypassing traditional card schemes at POS. Under Royal Decree 253/2025, banks must report all Bizum income linked to economic/business activity to the AEAT monthly, with no minimum transaction floor.
