Treasury and finance teams working with ING Wholesale Banking in Portugal can pull their corporate banking data into their own systems through open-banking.io.

Privacy by design

open-banking.io is built on a zero-knowledge model: your banking data passes through encrypted and is never mined or resold. There are no eIDAS or QWAC certificates to buy, install, or renew — the platform handles the regulated connectivity so your team doesn't touch PKI at all.

Pricing

Access starts at roughly EUR 3 per month, with the same flat, predictable cost whether you connect one ING account or dozens of banks across Europe.
