Kontoopplysningstjenester

Kontoopplysningstjenester, which translates to account information services, are a type of financial service that allows authorized third-party providers to access customer financial account data with the customer's explicit consent. These services are a core component of open banking initiatives, particularly prevalent in regions like the European Union under the Payment Services Directive (PSD2).

The primary function of kontoopplysningstjenester is to retrieve information about a customer's bank accounts, such as account balances, transaction history, and account holder details. This information is then made available to the third-party provider through secure Application Programming Interfaces (APIs). Customers typically grant consent through their bank's online portal or mobile app, specifying which accounts the provider can access and for how long.

These services enable a range of innovative financial applications and services. For instance, they are fundamental for account information service providers (AISPs) who offer budgeting tools, financial management platforms, and credit scoring services. By aggregating data from multiple bank accounts, AISPs can provide users with a holistic view of their financial situation, helping them make more informed decisions.

The implementation of kontoopplysningstjenester is governed by strict security and regulatory frameworks to protect customer data and privacy. Strong customer authentication and secure API protocols are essential to prevent unauthorized access. The consent mechanism is central, ensuring that customers remain in control of who accesses their financial information.
