Websites offering cheap goods and services should be regarded with care. Online shoppers who enter their credit card information may never receive the goods they thought they had bought. The thieves then go shopping with the shoppers’card numbers—or sell the information over the Internet. Hackers(黑客) have broken down security systems, raising questions about the safety of cardholders’information. Several months ago, 25,000 customers of CD Universe, an online music retailer( 零 售 商), were not lucky. Their names, addresses and credit card numbers were posted on a website after the retailer refused to pay $157,828 to get back the information. Credit card firms are now fighting against online fraud. Mastercard is working on plans for Web-only credit card, with a lower credit limit. The card could be used only for shopping online. However, there are a few simple steps you can take to keep from being cheated. Ask about your credit card firm’s online rules: under British law, cardholders have to pay the first $78 of any fraudulent(欺骗性的) spending. And shop only on secure sites: send your credit card information only if the website offers the advanced secure system. If the security is in place, the letter“s”will appear in the bottom right-hand corner of your screen. The website address may also start with “https:”— the extra “s” stands for security. If in doubt, give your credit card information over the telephone. Keep your password safe: most online sites require a username and password before placing an order. Treat your password with care.
