Trivial to do .. I seem to remember that it can be done using only stuff
you can buy at your local grocery store. Given that the fingerprint that
you want to spoof is likely to be on the reader from when the legitimate
user touched, this is no security at all.
With some cheap fingerprint readers, breathing lightly onto the reader,
to reactivate the latent print, is enough. Only slightly harder is the
manufacture of a gelatin reproduction ... do a google search for "gummy
finger".
