In order to activate fraud prevention, the tab "Fraud prevention" (optional) must be enabled for you within the application. You can use fraud prevention to blacklist card, account or device data, to view the blacklisted card, account or device data, to authorise credit card ranges and to view authorised credit card ranges. As an additional security measure, you can have velocity checks configured in your NEXI by NEXI Helpdesk.
Velocity checks
Velocity checks can only be created and viewed by NEXI Helpdesk.
Please contact NEXI Helpdesk to have velocity checks changed, created or removed.
Velocity checks are tools used to check parameters that are automatically queried each time before a payment process is created. A rule could, for example, be that a maximum of two payments are permitted using the same credit card within a given period of time. The application gives you the option with the tab "Black List SecurePay" to search for records within the blacklist imposed by velocity checks, or to delete them. The tab "White List SecurePay" allows you to exempt card, account or device data from the velocity checks. These card, account or device data may then be used to create payment process without limits given by velocity checks.
