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 financial APIs to External providers — with the explicit consent of the account holder. External providers can retrieve account information via these APIs (e.g. account balances, transaction history) or initiate payments on behalf of the account holder.
In the EU, the PSD2 directive (Payment Services Directive 2) forms the regulatory framework 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 are opening their APIs voluntarily — for example via the OpenBankingProject.ch initiative.
For e-commerce, open banking enables payment methods such as Pay by Bank: customers authorise a payment directly from their e-banking, without a credit card or Comerciante-wallet. This reduces transaction costs for Comerciantes.
Open Banking examples
A FinTech company offers accounting software that automatically imports the transaction history 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 card details.
A loan comparison portal uses open banking APIs to automatically analyse an applicant's financial data (with their consent).
