Okay, I've been doing more and more shopping on the internet and, while I'm pretty careful about not buying from websites that don't look legit, I'm not as careful as I should be. I know that some people are able to create 1-time use cards where you find out the total for something and then have a new credit card with a unique number issued for exactly the purchase amount. The amount is then taken from your real account, but that card then becomes useless even if it is stolen.
Is this a service offered by specific banks or credit card companies or can anyone do it? Specifically I want to start doing this with my Visa CheckCard because I know that debit cards offer less protection for theft/fraud than do credit cards.
Can anyone point me to a website where these disposable credit card numbers can be obtained?
