The Client of the project was a large international bank that offers services in the field of daily banking, personal accounts and credit cards, savings and loans, as well as in the fields of leasing, investment and insurance. The bank has an extensive network of its own branches and partner outlets throughout Europe and is considered to be one of the most innovative banks in Poland, very advanced in electronic banking.

Qualified electronic signature


The introduction of the electronic signature system in the organization was motivated by several important factors. First of all, it opened new possibilities for communication with people and organizations outside the client’s organizational structure. Another important aspect was the banking sector’s security requirements, which did not provide for the use of a lower security degree of signature than the qualified one.


The introduction of an electronic signatures system in an organization with such a large operating scale yielded tangible benefits – with a shipping plan of around 500 documents per week, the Customer could have saved tens of thousands of EUR a month in comparison to sending printed documents by post and signing them manually. Another important advantage was the significant saving of time for employees who had been responsible for the manual mailing of correspondence.

The implementation of the electronic signature significantly accelerated the process of communication with external entities in the client’s organization, as well as allow the organization to focus on strategic goals, leaving the repetitive but necessary tasks to the IT system. Digitization of the correspondence also made the management of it easier and less costly, because it was no longer necessary to store huge amounts of documents in secure cabinets.


The solution consisted of an implementation of a document handling system with the “ordinary” electronic signature. It was later improved by introducing qualified electronic signatures. The solution is fully compliant with the eIDAS regulation, thanks to which documents can be authenticated throughout the European Union. An important feature of the system is the possibility of two-way operation. The system allows for the validation of documents coming from third parties, as well as for signing documents leaving the client’s organization. As the system is based on service architecture, it is possible to easily use its functionalities in existing business applications without the need to make time-consuming and expensive changes to them.
