US Patent 11763381 Dynamic unauthorized activity detection and control system

Systems for dynamically detecting and controlling unauthorized activity are presented. In some examples, a request for a withdrawal may be received by a self-service kiosk. A plurality of bills may be transferred from a storage area to a dispensing device of the self-service kiosk. In some examples, the plurality of bills may be scanned to capture data associated with each bill. This data may be stored in a bill identification database. An error notification may be received by the self-service kiosk from a user. In response, bills within the self-service kiosk may be scanned to identify unique identifiers associated with the bills in the self-service kiosk. If the bills identified as dispensed are present, an error or malfunction has occurred and a user account may be credited. If the bills are not present, the activity may be identified as unauthorized activity and one or more mitigating actions may be executed.
