According to the Act on Credit Institutions and the Act on Detecting and Preventing Money Laundering and Terrorist Financing, the bank must identify its customers, authenticate the customers’ identity with a document accepted as a proof of identity and store the information of that proof of identity in its archive. The bank must also know what kind of business the customer has with the bank and what kind of services the customer wishes to use. The bank is obliged to monitor the customer’s business and use of the service so that the bank can identify any unusual or deviating transactions and react to them. The so-called due diligence information collected by the bank includes, in addition to the basic information, information about financial standing, tax liability and political exposure. Danske Bank collects due diligence data when the customer relationship is started and regularly after that. The bank has a statutory obligation to assist in the prevention, exposure and investigation of criminal activity and having possible crimes investigated.
