I have heard a lot about fingerprint readers being built into devices such as notebook computers and PDAs. Do you know if the same technology is available in a mobile phone?
Name and address supplied
DQ: There is such a mobile phone - the Pantech GI100, which you can investigate at www.gsmarena.com/pantech_gi100-806.php. But it is unlikely to interest anybody because it is old and does not include many features we now take for granted, such as Bluetooth.
More interestingly, Japanese electronics manufacturer Sharp is including new technologies that will enable fingerprint-reading on the screens of its mobile phones. Have a look at gizmodo.com/gadgets/cellphones/sharps-next-gen-mobiles-to-pack-fingerprint-reading-touchscreens-239614.php.
Before you get too excited about that development, I suggest caution. Some people have complained a fingerprint reader on a mobile phone should not be on its screen; it will get filthy if a user is constantly touching it.
Just to throw a spanner in the works, have a look at this rather sobering video at www.youtube.com/watch?v=E20lHqbWqN4. Although it takes some effort, it is not impossible to 'steal' somebody's fingerprint, make a latex copy of it then open any lock that depends on that digit's impression. Little is truly safe in this world.
