  This paper describes the operational evaluation of a door-opening system
based on a low-cost inkless fingerprint sensor. This system has been developed
and installed for access control to one of our laboratories. Experimental
results reveal that the system is working fine and no special cleaning
requirements neither components replacement is needed. It can support more than
50 users, and an average of 74,5 access attempts per day in a 14-hour
5-day-per-week working. Emphasize is also given on some important facts to be
taken into consideration when comparing and evaluating different products from
different vendors.
