LYNX
Lynx is a high-tech neural system like no other in the world. It undoubtedly helps to make VisaNet Brasil the most secure electronic payment company in Brazil. Lynx is an anti-fraud system that can detect whether a transaction may pose a potential fraud risk-with a high level of accuracy-at the moment of the purchase.
The system immediately alerts the issuing bank, which may then choose between several courses of actions, such as, do not authorize the transaction, take preventive measures (like contacting the cardholder to make sure the transaction is legitimate), or take corrective measures (like blocking the card).
