By Delilah Obie, Contributing Author Software and e-commerce services are available to help reduce a seller's risk of fraud. Two such services are CyberSource and Fraud Shield. Companies such as CyberSource provide a full suite of e-commerce solutions, including a payment gateway that screens for credit card fraud.
Merchants determine their level of risk tolerance and decide whether to accept or reject the order.
IFS issues scores ranging from 0 to 99. Under this rating system, the higher the score, the higher the risk, which means that an order with a score of 80 represents twice the risk of an order with a score of 40. Merchants who accept Visa cards are given further discounts, and pricing begins at 20.4 cents and can be as little as 15.7 cents for a higher volume of transactions. Fraud Shield performs a variety of Internet-specific checks, but lets merchants define their own rules from selected data fields. These checks can verify whether shipping and billing addresses match.
