The cleanest way to implement this sort of single-use device is
to build a custom ROM image and flash it to the devices to be
used.  This obviously requires that you have access to the hardware
but since this requirement is usually for devices distributed to
workers the requirement isn't as limiting as it seems.

I can't point you to resources because the last time I did this was
several years ago but, although it seemed difficult I found that
after following the instructions carefully I had a ROM image
that only included software the client wanted to be available.

If this approach doesn't suit your situation you're down to fixes
such as installing hacks to trap keystrokes.  The problem is that
a hard reset will always remove these applications, reverting
the device to the factory state.
