TIMETRAX BIO
Q. HOW ACCURATE IS THE TIMETRAX BIO?
A. The accuracy of fingerprint readers has increased dramatically in the
last few years. Error rates have been steadily declining as matching and
sensor technologies evolve. Pyramid’s False Reject Rate is less than half
a percent. The False Accept Rate is even lower.
•
False Reject Rate:
The hardware decides there is no match when
there is, in fact, a match. When security is less important and it
is important to do the best you can with only one measurement,
you want a low False Reject Rate.
•
False Accept Rate:
The hardware decides there is a match when
there is, in fact, no match. When it is really important to be sure
that there is a match, you want to have a very low False Accept
Rate.
Q. DOES TIMETRAX BIO PROTECT MY FINGERPRINTS FROM
BEING USED WITHOUT MY KNOWLEDGE?
A. The TimeTrax Bio does not require much data to recognize a fingerprint.
The reader scans the finger and stores only data concerning distinctive
portions of the fingerprint called “minutia points.” The minutia points
are only a mathematical representation of some data from the original
fingerprint. A complete image of the fingerprint is never stored on the
system. Because it is a one-way function, it is impossible to reconstruct
the fingerprint using these points.
Q. WHAT HAPPENS IF THE TIMETRAX HARDWARE BREAKS?
WILL I HAVE TO RE-ENROLL EACH EMPLOYEE FINGERPRINT
AGAIN?
A. Yes. TimeTrax Bio terminal stores the fingerprint. If the terminal should
cease working, fingerprints would have to be re-enrolled.
Q. DOES THE CENTRAL COMPUTER WITH THE TIMETRAX
SOFTWARE LOADED ON IT HAVE TO BE ON TO RECEIVE
FINGER SWIPING PUNCHES?
A. Since the TimeTrax Bio terminal stores the fingerprint vs. the software
storing the fingerprint, employees can continue to swipe if the computer
systems are down. Punches can be downloaded from the terminal once
the power or system is restored to normal working conditions.
