1. Add a message to shopping cart (or auction ad) that says, “We screen for credit card fraud.” This cuts out about half of your fraud problem.
2. Require complete information from buyer in checkout proce dure.
3. Require the card verification number (CVV2) printed in the back of the credit card.
4. Use the Address Verification System (AVS) system. This system determines whether the address submitted by the buyer matches the address on record for the card. If the addresses don’t match, don’t sell.
5. Verify the credit card holder’s address address through a Web mapping service.
6. Telephone the card holder’s bank for verification information.
7. Check the Bank Identification Number (BIN) for the credit card to see if issuing bank is in the US.
8. Use HTTP_USER_AGENT and REMOTE_ADDR code in your forms that gather crucial information on buyers.
9. Check IP address to see if it’s in the US and near the address of the card holder. Go to ARIN (http://www.arin.net) and search WhoIs.
10. Telephone card holder to determine whether they ordered the item from you.
11. Request faxed signature with copies of front and back of credit card.
12. Don’t sell to holders of free email services such as Hotmail, as it will be impossible to trace them.
13. Communicate with buyer. It may uncover an undeliverable email address or a bogus telephone number. Ask for confirma tion of details of the order.
14. Be extra cautious with multiple-item or high-dollar orders.
15. Be extra wary when buyer specifies overnight shipping.
16. Don’t ship to outlaw countries (see below).
17. Also follow the PayPal list below.
1. Ship only to PayPal member’s confirmed address. Use shipping that you can track and get a receipt.
2. Check the buyer’s reputation. Duh!
3. Accept payment from only one PayPal account.
4. Limit PayPal payments to exclude credit-card backed accounts. (This is a harsh policy.)
5. Beware of buyers who are not concerned with shipping costs.
6. Be extra careful when a buyer is buying items that can easily be resold.
7. Ship cautiously to other countries. Ship only to countries on PayPal’s approved list.
SET
The credit card companies created a system a few years ago that is substantially more secure than the haphazard system we live with. It’s called SET (Secure Electronic Transactions). As credit card fraud continues, you may see it become more popular.
