Description

The Project at VISA, Foster City, CA: Advanced Authorization Workstation (AAW) is an application to provide to enhance Risk Management Capabilities and CAMS (Compromise Account Management Systems) provide a way to handle all compromised accounts via a web-based application. All these applications fall under VRM (VISA RISK MANAGER) System umbrella. Visa is in the unique position to provide members with a web-based, risk workstation that provide direct access to Visa Net systems and processing. The product vision originated from a need to provide Members with an interface that allows them to view risk management operations and analytical functions as an end to end process. Currently, several product gaps exist that prevent Visa Risk from providing a complete view of risk management operations to Members. Fraud is an ongoing threat to the payment system. Visa is in the unique position of providing an integrated suite of risk management tools. The risk workstation will facilitate the Real-Time, authorization decision strategies and will automatically report fraud to Visa to ensure the Risk Models have timely access to the fraud data.
