Image consistency

Once a user’s fingerprint template has been enrolled, the best performance in the
candidate matching process depends on consistency. Obviously, the user must use
the same finger for ID verification as was used to form the original template. It also is
important to position the finger correctly for each verification, as was done when the
template was enrolled, so the Veriprox “sees” approximately the same information
each time.
