Visa to Enhance Its Advanced Authorization Technology to Fight Fraud
Oct 2, 2013 (Wed): Visa today announced a series of enhancements to Visa’s Advanced Authorization (VAA) technology to offer the potential to substantially reduce fraud in both “card present” and “card not present” transactions.
The enhanced model includes additional risk indicators specific to Automated Fuel Dispensers (AFD) transactions which can pinpoint suspicious activity at a gas station and apply that to all transactions processed through that station.
Visa has also increased the breadth of each account profile in the Advanced Authorization model by adding more transactional history data, along with additional neural networks to analyze that data. The account profile is a major component of the risk score assigned to a given transaction and provided to the issuer for them to make an authorization decision.
