MaxMind verification service

MaxMind minFraud is a transaction fraud detection service which checks the transaction parameters against MaxMind fraud databases. If the verification is enabled for a shop, the PayCross system response contains the max_mind_verification section specifying the score and the status. The higher is the score of the transaction, the greater is the risk attributed to this transaction.
