Open Banking

Open Banking enables External providers to access bank data and initiate payments via standardised APIs — with the consent of the account holder.

Open Banking

Open Banking refers to the opening of bank interfaces (APIs) for External providers — with the explicit consent of the account holder. External providers can retrieve account information (e.g., account balances, transaction history) or initiate payments on behalf of the account holder via these APIs.

In the EU, the PSD2 directive (Payment Services Directive 2) forms the regulatory basis for Open Banking. It obliges banks to grant External providers access to account data, provided the account holder consents. In Switzerland, there is no PSD2 obligation, but many banks open their APIs voluntarily — for example, via the OpenBankingProject.ch initiative.

For e-commerce, Open Banking enables payment methods such as Pay by Bank: your customers authorize a payment directly from their e-banking, without a credit card or External provider wallet. This reduces transaction costs for merchants.

Open Banking examples

A FinTech company offers accounting software that automatically imports the transaction data of business accounts via an open banking API.

An online shop offers Pay by Bank: customers select their bank, log in and authorise the payment — without entering any card details.

A loan comparison portal uses open banking APIs to automatically analyse the financial data of an applicant (with their consent).
