An apparatus for input and fingerprint recognition on a handheld
electronic device includes (1) a touchscreen having a touch resolution
portion and a fingerprint sensor distinct from the touch resolution
portion; and (2) a data processor coupled to the touchscreen. The touch
resolution portion has a touch resolution for detecting a touch input on
the touch surface. The data processor is configured to selectively
operate the fingerprint sensor in one of a fingerprint resolution mode
for sensing a fingerprint on said touch surface and a touch input mode
for detecting the touch input on said touch surface.
