Gates and his new Security technology - Infocard

Gates delivered a keynote address at the RSA Conference 2006 and has shared his vision of Security in Windows. Seems like most of their investments in 2005 was on Security. He talks of a new technology called Infocard which can be used to Authenticate / Authorize people which could eliminate the Userid/password based systems. Lets wait and watch if Infocard can really do the magic..
