That's not true. If you have correct permissions then no sudo is needed. 
In fact, running fprint_demo under sudo is a bad idea - fprint_demo uses 
GTK+ which uses many other things, and you end up running several 
millions of lines of code as root.

In terms of needing root to enroll fingers though, fprintd will 
eventually allow for control over who can/can't enroll using PolicyKit.
