You can have velocity checks configured in your NEXI Merchant Portal as an additional security measure.
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 an operation is created. A rule could, for example, be that a maximum of two payments are permitted using one credit card within a set period of time. When the maximum number has been exceeded in the set period of time, a temporary list entry with the card, account or device data is automatically created in the SecurePay black list. These card, account or device data cannot be used to create operations any more for the specified time. Once the set time has expired, the temporary list entry is automatically removed from the SecurePay black list again.
You can use the tab "Fraud prevention" → "Black List SecurePay" to search for and filter blacklisted card, account or device data. This allows, for example, card, account or device data temporarily blacklisted by one of your support staff to be enabled again. You cannot create temporary list entries. The application does, however, provide you with the option of blacklisting card, account or device data permanently in the tab "Fraud prevention" → Black list".
