Telephone Verification Service Usage

The Telephone Verification service can be implemented as an independent service or can be used in conjunction with the minFraud fraud detection service for optimum protection. Businesses can customize the Telephone Verification service as well. For example, the setting can be adjusted on the client side so that your system requires a telephone verification only from customers who are using free email addresses or orders that have a score above a certain riskScore threshold value. The threshold values can be re-adjusted at any time.

To see how Telephone Verification can be integrated into the payment process, refer to the following diagrams:
