Abstract:

Provided are systems, methods, techniques, instruction sequences, and computer program products associated with and configured to the technical field of special purpose machines that facilitate generation and provision of application program interfaces (or APIs). The APIs automatically compare the geographic position of a user resource with a known database of events to determine the likelihood that the user is attending the event. In response to determining that the likelihood exceeds a predetermined limit, the APIs communicate notifications to update user information to service providers, such as financial networks, to improve the performance of the user's portable financial devices and reduce financial fraud associated with offline transactions.
