Casio has developed a 1.2″ LCD screen with a fingerprint sensor layered into it.
The idea behind the concept is to built biometric security into cellphones without needing a seperate sensor.
Casio said it could also be used in PDAs (but that would require a larger, higher resolution LCD).
Sounds nice but what I don’t get is: why would I want a PDA or cellphone whose LCD screen is always covered in greasy dirty fingerprints?
