Most payment processing companies wil automatically check orders for obvious signs of fraud and / or allow you to set the conditions yourself through their admin area. Checks are often made on AVS, CVV but may include transaction amount, known bad IP addresses or ranges as well as rapid multiple orders amongst others.
The important consideration is not to rely 100% on your payment proceesor to pick up on fraudulent orders and that is why we recommend manually reviewing each and every order. The steps below are a guide to checking for fraudulent orders.
AVS (Address Verification Service)
Check on the card holder's billing address. This will match the address given on checkout with the records held by the bank for the address of the card holder
CVV (Cardholder Verification Value)
A check on the three digit number on the back of a credit card.
The address of the the computer from where the order originates, this will be in the form of numbers like 188.8.131.52
When a customer contacts the credit card company disputing the purchase. This may be due to fraud or displeasure with the product received. Chargebacks will incur an extra fee, depending on your payment processing company, and may result in the closure of your account.
