Hi Kunal,
the program on example directory (like fprint_demo and pam_fprint)
receive the result and re-call the action if not completed.
The daemon fprintd (and fprintd-verify) when receive "remove finger"
result wait for another image without re-call the action.
Try the new patch. It seem to work with all these program.
Bye
Sergio
