Finally, identity thieves are reaping high rewards at the expense of both the target and the online retailer.

Below are advice and tips for credit card customers or buyers when receiving an e-mail that may be fraudulent:

1. Buyers need to be cautious about e-mails that offer credit services because many unsolicited e-mails are fraudulent. Buyers also should not simply click on Internet hyperlinks within received e-mails. Instead, buyers can type in the known URL into the address bar of the web browser.
2. Buyers need to be wary of e-mails which offer prizes or discounts and then asking them to choose a User ID and Password. Most people use the same access information for several accounts because they are easier to remember. The thieves will collect your login information and try them at other sites, like financial institutions or credit-card sites.
3. Buyers should never respond to e-mails that request for credit card information and also do not ever respond to e-mails that ask them to go to a website to verify personal (and credit card) information. If buyers have doubts about the authenticity of an e-mail, do not respond to the e-mail. Alternatively, they can call the sender to verify or manually type in the web address.
4. Buyers need to be wary of e-mails with a sense of urgency which attempts to rush buyers into action. For example, “Update now or we’ll close your account… …” Please note that fraudulent e-mails often include misspelling and poor grammar within the e-mails.

3. Merchants have to be wary of orders which ask for express, rush or overnight shipping because these are the shipping of choice for many credit card fraudsters. Merchants need to call the customer to confirm the order first.
4. For overseas orders, especially if the order exhibits any of the characteristics noted above, merchants must be wary of them.

Merchants should not simply process credit card orders that originate from free e-mail addresses or from e-mail forwarding addresses. In such cases, merchants should ask the buyer for an ISP or domain-based e-mail address that can be traced back before processing the order.
2. Buyers must only give their credit card details to reliable websites which are from reputable companies. In addition, reputable merchant sites usually use encryption technologies to protect credit card information.
3. Merchant should not process credit card orders unless the credit card information of that buyer is complete. If the shipping address and the billing address on the order are different, merchants need to call the buyer to confirm the order. Merchants may even want to make it a policy to ship only to the billing address on the credit card.
4. Buyers must be very careful with to whom to give personal identification information, such as mother’s maiden name and social security number. Buyers have to ask if the information can be kept confidential and inquire how it will be used and with whom will the information be shared.
5. Buyer also must never send account information, such as account numbers or PIN in an e-mail as it may be intercepted.
