Token-based security processing

Abstract:

A user is authenticated for a session with a server, the server generates a unique session token valid during an active session with the server. Valid outstanding transactions for the active session are presented to the user. A selected outstanding transaction is provided to a Self-Service Terminal (SST) with the unique session token. The SST validates the unique session token and the selected outstanding transaction with the server. Upon confirmation from the server, the SST completes the selected outstanding transaction at the SST.
