How to implement device velocity check

Device is a type of electronic hardware that clients used to access your website or making a purchase. The device could be a desktop, laptop, hand-phone, tablet and so on. This electronic device can be uniquely identified using the FraudLabs Pro Agent Javascript technology (a.k.a. device fingerprinting).  Why is this device identification important? It is because this identification helps you to unveil one of the common fraud patterns used by perpetrators to camouflage themselves as legitimate unique buyers. For example, a fraudster could use an email,, with IP address to make a purchase. Few minutes later, the same fraudster could use another email,, with IP address to make another purchase. This fraud tactic requires minimal effort as the above information can be easily changed and spoofed. But, if the fraudster used the same device for this malicious activity, this can be detected using the Device Velocity rule. This is because the electronic device used by the fraudster has been labeled with a unique tracking number by the system.
