Operations: Thwart Online Fraudsters

¥ Velocity checks can help you avoid this scenario. Devise a system that flags orders containing repeat occurrences in any captured data field -- for example, the credit card number field -- over time.

¥ Flag for other suspicious order characteristics as well, such as a series of orders shipping to the same address but using several different credit card numbers, or an IP address from which you’ve logged several orders arriving within a short period of time (e.g., an hour or two) but using different credit card numbers. All are signs you may have been targeted by fraudsters.
