Abstract: The invention provides Users of Retail Payment and Identification instruments with the ability to review transaction details and approve transaction by capturing UVM in User controlled environment and Issuers of these instruments with the ability to positively authenticate Users in Issuer controlled environment. The invention accounts for real time legacy or non-legacy processing systems to provide an authorization request from POA to Issuer Host. The invention introduces two UPAAS components—User Gateway and User Application. The UPAAS User Gateway is implemented in an Issuer controlled environment enabling interface between Issuer legacy Host and UPAAS User Applications. The UPAAS User Application can be implemented on any device supporting communication protocol such as TCP/IP without any hardware changes enabling the User to login to UPAAS User Gateway, review and approve or decline a specific transaction in real time by entering UVM, such as PIN, for User authentication purposes.
