About Fraud prevention with IP tracking

General information about Fraud prevention

Pay-Jet Cockpit supports different processes for fraud prevention. These include inquiries with credit agencies for the monitoring of the card's country of origin and payment guarantees for credit cards.

A large proportion of fraud attempts come from foreign countries. Pay-Jet Cockpit can check the country of origin and, in many cases the city of the IP address used. If the country of origin or the IP address of your customer is not one of your supplies countries or is not the same country as the credit card Issuer, Pay-Jet Cockpit can send an alert via e-mail or automatically refuse the payment.

75% of all fraud attempts are made with foreign credit cards. Pay-Jet Cockpit can check the card’s origin: If you enter the delivery country as a parameter, Pay-Jet Cockpit returns the country of origin of Visa and MasterCard issued cards and sends an e-mail if the delivery country differs from the card’s origin. You can then find out from the customer why the card’s origin differs from the delivery country to avoid fraud. Pay-Jet Cockpit can optionally refuse such payments immediately.
