A common tactic in this type of fraud is to hide the location of the purchase by hiding the IP. Many methods can achieve this purpose, the most common ones being VPNs or cloud-based servers. A fraud attempt can also be made through a proxy, which has the same effect. For this reason, an IP verification process can also be used to detect suspicious purchases. It is essential to consider the fact that many people are using VPNs and other methods nowadays to keep their information as private as possible. So, you should determine the validity of a purchase based on this factor alone. It is best used together with other methods. The more factors you have to make a decision, the more accurate it will be and the lower the chances that you will block a genuine purchase.
