InfoCard Explained

Infocard Explained , it's a nice video about infocard (a new identity management in vista, based on winfx). I think one of them in the video (the program manager of infocard) is indonesian, hmm, am i right ??? CMIIW..... And the nicest thing about infocard is that we can use this identity/credential for our WCF services, we just have to set some xml config for our WCF services and then when our program invoke that services , the infocard dialog will popup and ask us to choose the card that we want to use, cool right.... No more hassle in remembering all those kind of password and user for different services and websites.... We can integrate it all into a single sign-on using infocard and the UX (User Experience) is very good. Enjoy !!!
