What data you can access

Once consent is granted, you can retrieve:

  • Accounts — details for both business and personal Merck Finck accounts.
  • Balances — current and available figures, refreshed on demand.
  • Transactions — historical and incoming entries with counterparties, amounts and dates.

Merck Finck supports a maximum consent window of 180 days, after which the account holder simply re-authorises to keep the connection live. Both business and personal account types are covered, and the same integration extends to thousands of banks across the EU and UK — no per-bank contracts required.

Privacy by design

open-banking.io runs on a zero-knowledge model: we never store your users' banking credentials, and there are no QWAC or QSEAL certificates to purchase, install or renew. Data flows through the account holder's authenticated session, so you stay lean and compliant while we handle the plumbing.

Pricing

Flat and predictable at roughly EUR 3 per month — no setup fees, no volume surprises. Scale from one Merck Finck connection to your entire European footprint on the same simple plan.
