The device tracking add-on for the minFraud services identifies devices as they move across networks and enhances the ability of the minFraud services to detect fraud. If a fraudster changes proxies while they are browsing your website or between visits to your website, you may observe an increased riskScore in the minFraud output associated with their transactions.
We may increase the risk score if we detect order velocity on the device. We also return a device ID in minFraud Insights and Factors so that you can do your own modeling around device ID.
Note that, in order to be effective, the Device Tracking Add-on must, at a minimum, be included on the page where the IP address is captured for a minFraud query.
If you anticipate volume greater than 100 page views per second, please contact us.

MaxMind may use other browser storage techniques in the future to enhance the performance of the device tracking add-on.
