The anti-fraud system used is provided by our card processing partner. One of the fields used for data checking by the anti-fraud system is the email address, so it's extremely important to fill it in correctly. The anti-fraud system offered in our Credit Card solution is essentially a neural network composed of an interconnection of various databases with multiple indexing rules and dynamic relationships.
This network is used by our processing partner's machine learning engine to feed the risk analysis rule trees, with changes in behavioral patterns of each scenario mapped in each rule of the tree to ensure that false positives do not contaminate the analyses.
It is also possible, through detailed analysis, to add emails to a Free list and a Block list, to release or block buyers according to their consumption profile, thus increasing the approval rate of purchases without compromising security.
