I know alot of us buy things online with our Credit Cards.  And I do think alot of companies do great things to protect your privacy and secure your transactions.  But with recent hacks of major servers with personal data being compromised I've started taking the need to keep my Credit Card info more private.  For this reason I was really glad to see that CitiCard has a Virtual Card number applet that you can run from any web browser, and gives you a Credit Card number that is good for 1 month.  I generate one for every purchase I do on the web, and have felt MUCH better about my private information remaining private.
