FingerLoc®
AF-S2
Fingerprint Sensor
Introducing…
The FingerLoc AF-S2 is
AuthenTec’s workhorse fingerprint
identification sensor IC, using
familiar and reliable 0.6µ CMOS
technology. This product combines
silicon-based image capture with
proprietary sensor control and
matching algorithms.
AuthenTec sensors with TruePrint®
Technology look past the easily
obscured outer surface of the skin
to the living layer below where the
unique ridge and valley patterns of
the fingerprint originate.
AuthenTec devices are the first and
only fingerprint-based biometric
authentication solutions that can
work for everyone, everywhere,
under the most demanding real-
world conditions.
TruePrint Is…
AuthenTec’s unique, patented
imaging technology. During
imaging, a small signal is
generated between the IC and the
finger’s live layer. More than
16,000 individual elements in the
sensor matrix form a planar
antenna array that receives this
signal, creating a digital pattern
that mimics very accurately the
fingerprint’s underlying structure.
A powerful component of TruePrint
is called Dynamic Optimization.
This tool analyzes each frame,
controlling up to 15 parameters to
optimize the fingerprint image,
regardless of unusual skin
conditions or surface
contamination.
Superior Image Quality…
The result is a high-quality image
that creates reliable
authentication. These images
ensure that we capture everyone,
every time under virtually all
conditions.
Target Applications…
The FingerLoc AF-S2 sensor is
optimized for use in time and
attendance, access control, and
security applications, and in large
form-factor PCs and peripherals.
Convenient Security…
The FingerLoc AF-S2 fingerprint
sensor is specifically designed for
the demands of the PC market
and access control markets. Its
small size and high repeatability
make it ideally secure, reliable,
and convenient for such
applications.
Building On Success…
FingerLoc is AuthenTec’s original
fingerprint sensor family, which
compliments the EntréPad® line
for the portable PC and mobile
product markets.
Both product families build on
AuthenTec’s well-proven
TruePrint Technology to produce
the best images in the industry.
