Another way to prevent fraud is by paying close attention to the address verification
response. If the address and/or post-code do not match the card-issuing bank's address on
record, there is a higher probability of fraud.
Furthermore, for your protection, we urge you to regularly use the card code field.
5.1.1 Blocking Credit Card Numbers
The first setting you will encounter when you bring up Fraud Settings is Block Card. Here you
can enter the credit card numbers that you do not wish to allow to purchase at your store.
Fraud prevention: Blocking credit card numbers
If you have any credit card numbers already on your blocked credit cards list, they will
automatically appear in the select box on the right side of the screen when you enter this
page. Bring up Fraud Settings by clicking on Admin in the Main Menu Bar, then on Fraud
Settings in the Side Menu Box.
Adding a card number
To add a card number to your blocked card number list:
1. If the Block Card page is not already displayed, click the Block Card link in the top
navigation found under the main Fraud Settings title.
2. Enter the card number you wish to block in the Card # input box on the left-hand
side of the screen.
3. Then click the Add >> button. Spaces and/or dashes are optional.
4. When you click the Add >> button, the change is submitted to the Internet Payment
Gateway, we add the card number to your list of blocked card numbers, then we regenerate
the page with the new card number in the select box at the right side of the page.
If this blocked card should be used to attempt to purchase anything at your store, the
transaction will be declined because of fraud.
