Device Tracking Add-on for minFraud and Proxy Detection Services

The device tracking add-on for the minFraud and Proxy Detection services identifies devices as they move across networks and enhances the ability of the minFraud and Proxy Detection services to detect fraud. If a fraudster changes proxies while they are browsing your website or between visits to your website, you will observe an increased proxyScore and/or riskScore in the minFraud and Proxy Detection output associated with their transactions.

Recommended Use

We recommend including the JavaScript below on your shopping cart page or the first page in your checkout process. If you receive a significant number of fraudulent purchases, you may wish to include the JavaScript on other pages in order to detect fraudsters if they change or enable proxies while browsing your website.
