The paper discusses the importance of The Society for Worldwide Interbank Financial Telecommunication (hereinafter "SWIFT") not only for European integration. It partially maps its historical development with emphasis on the importance for mutual communication between financial institutions. At the same time, however, it can be a very suitable means of obtaining a range of information as evidence for criminal proceedings in clarifying financial crime offenses. In their research, the authors deal with various approaches to the processing of data obtained from the SWIFT system, which will be submitted to law enforcement authorities. These documents can then be linked to other information, which in turn will help clarify possible financial crime, especially in cross-border, or foreign overlap. The authors' study is based on the hypothesis that "SWIFT information can contribute to the clarification / detection of financial crime".
