NFC Logon allows owners of the above tablet/laptop hybrids to easily log into Windows by tapping their NFC-enabled Android phone against the device. The application itself is very simple, requiring only that the user enters their username and password (with an option to save the password for future use), before tapping it against the tablet.
Although I'm currently unable to test it myself, it would appear that the application simply pushes an NDEF payload containing the user's credentials via NFC, so there is no card emulation involved here. Any updates will be posted here.
