·
Password / Fingerprint Access – you can define the period in which password
can be used instead of fingerprint for access. This is particularly useful if you
want to just use password to access during normal office hours, but to restrict the
access to authorized people only after office hours.
As a Time Attendance System:
·
Default Clock-In & Clock-Out time – you can setup the default clock-in time &
clock-out time, so the user does not need to specify every time when he/she
clocks in & out.
·
Totally eliminate the buddy-punching problems & other frauds.
HOW IT WORKS?
iGuard FPS110 uses a solid-state sensor that images fingerprints by measuring
capacitance. Its rugged, silicon-based design offers substantial advantages over
optical-based sensors.
Beneath the sensor’s surface passivation layer is a 300 x 300 array of capacitor
plates (90,000 capacitors) spaced with a 50 mm pitch. The diagram above shows
that the ridges and valleys of the fingerprint at different distances from the capacitor
plates. That difference corresponds to a capacitance difference measured by the
sensor. An on-board analog-to-digital converter converts each capacitance
measurement into an 8-bit digital value, and then forms the fingerprint image. The
system then extracts a set of characteristics unique to that fingerprint, called minutia.
This minutia data uniquely identifies an individual.
