Credit card fraud is a growing problem for online merchants. As the merchant, you are liable for fraudulent credit card transactions, as well as chargeback fees. Excessive chargebacks can lead to losing your merchant account and being unable to open another one.
MaxMind Credit Card Fraud Detection tools automatically sift through your online charges to flag potentially fraudulent transactions. The service works by combining MaxMind GeoIP geolocation metrics - identifying the geographic source of the charge - with additional checks for known security risks. MaxMind tools pin down potential fraud and identify associated risk factors, pointing you to the best strategy to verify the flagged transaction and prevent future fraud.
You will need a MaxMind account, which is free, to use this service. Read more about it on http://www.maxmind.com/app/ccv2r_signup
