Alps fingerprint scannerWe swear we've already written about something similar to this (and indeed we have), but Alps Electric (which may or may not be a Swiss company — probably not) is working on what they say is the world's thinnest biometric fingerprint scanners for cellphones and PDAs. The idea is that you can use fingerprints as a more secure way to authenticate paying for things using cellphones, but with handsets getting smaller and smaller, where are exactly are they planning to put a fingerprint scanner? The only thing we can think of would be to have the phone's LCD screen double as a scanner, which surely can't be impossible (though it might be expensive).
