When you are an ecommerce merchant, credit card fraud is a serious concern. What most people may not know is the reason it is such a high concern to the merchant is because the burden of fraud falls on them. While it is great that the credit card banks, Visa, and Master Card protect the card holders from the fraud and limit the responsibility of the card holder to virtually nothing, they force merchants to pay for the cost of fraudulent transactions. Not only does the merchant lose the merchandise and shipping involved in sending out an order, but they are also charged a fee by the banks when the charge is disputed by the card holder. Therefore, preventing fraud and knowing what to look for is imperative for merchants. Unfortunately, contacting your merchant bank does not always yield a helpful result, so get educated about detecting fraudulent orders on your own.
