ING Bank Śląski's online transaction system has introduced a functionality that allows users to access their accounts from other banks. For now the service is available for accounts from two banks, mBank and Millennium, but the list will be extended with time. ING is the first bank on the Polish market to introduce this service, which became possible thanks to open banking regulations included in the PSD II directive.

ING's press office has said that this latest innovation allows customers to access account and card information without having to log in to multiple online banking systems. This means that users will be able to make transactions, such as money transfers, from accounts they have in different banks, via the ING interface. ING states that accessing accounts in different banks will be free of charge, safe, and compliant with PSD II standards.

In order to add an account from a different bank to an ING online banking interface, you need to log in to your ING account, find the functionality and select the bank in which you have your other account. During the process, you will need to accept the necessary conditions and authorize the operation in the system of the bank you have the other account in, as well as in the ING system.
