The Internet has led to a huge increase in credit-card (信用卡) fraud. Your card information could even be for sale in an illegal Web site (网站).
Web sites offering cheap goods and 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 the 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, an on-line music retailer (批发商) , were not lucky. Their names, 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.

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 with https://—the extra"s" stands for secure. If in 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 passwords with care.
