How to Beat On-line Credit-card Thieves

The Internet has led to a huge increase in credit-card fraud. Your card information could even be for sale in an illegal web site.

Web sites offering cheap services should be regarded with care. On-line shoppers who enter their credit-card information may never receive the goods they thought they bought.

The thieves then go shopping with your card number--- or sell the information over internet.

Computers hackers（黑客） have broken down security（安全） systems raising questions about the safety of cardholder information. Several months ago, 25,000 customers of CD Universe, and on-line music retailer（批发商）, were not lucky. Their name, addresses and credit-card numbers were posted on a web site after the retailer refused to pay US $157,828 to get back the information.

Credit-card firms are now fighting against on-line fraud. Master-card is working on plans for Web-only credit card, with a lower credit limit. The card could be used only for shopping on-line. However, there are a few simple steps you can take to keep from being cheated.

Ask about your credit-firm’s on-line rules. Under British law, cardholders are responsible for the first US $78 of any fraudulent spending.

And shop only at secure sites: Send your credit-card information only if the web site offers advanced secure system. If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The web site address may also start the extra “s” stands for secure.

If you still have any doubt, give your credit-card information over the telephone.

Keep your password safe: Most on-line sites require a user name and password before placing an order. Treat your password with care.
