Finger print readers on laptops - Using mouse pad instead
I have seen that some IBM laptops come with a seperate Finger Print recognition hardware. This is an add-on and additional inconvenience to the user before he starts working.
An alternative - how about using the tap pad itself as a finger print recognition hardware? The user anyway uses this (in most cases) piece of hardware. So instead of providing a seperate hardware, the same mouse pad can be used of authentication purposes.
More intelligence can further be built (in conjunction with OS) so that when the user taps, he can be automatically login into OS.
