Manual review of transactions
......................................................................................................................................................................................

Often, the most effective tool against transaction fraud is to manually review each transaction. The list below provides a few suspicious circumstances, which may lead to transaction fraud:

• A shopper ordering unusually large amounts of an item without any preference for the size, colour, make or model
• An existing shopper who suddenly orders a substantial volume of goods
• A shopper who provides you with more than one card to cover one order or a set of orders
• A shopper who orders more than once in a given day
• A first time shopper ordering a number of goods quickly
• A number of large orders from shoppers at a trade show
• A shopper who has attempted the same transaction more than once, with the card failing at the first attempt
• A shopper whose card issuer country does not match their delivery address.
• A shopper who refuses to confirm their credit/debit card and billing address details.
• A shopper who has purchased their goods /services from one of the following countries:

As the process of reviewing each transaction by hand is both time consuming and expensive we recommend that based on the circumstances above you create your own fraud prevention rules, which flags such unusual transactions for further research.
