6. FINGERPRINT MATCHING
Step1. Install “FM220 Demo Program.”
Step2. Select“FM220 Demo Program “and left click and select” FM220ISODemo.”
Step3. Press the Snap and GetTemplate botton to check the fingerprints quality.
It is recommended to use the index finger or the middle finger for optimal fingerprint
recognition performance.

Step4. Follow the diagram instructions to Enroll clear fingerprints into the Host
Device or PC. Press and release the finger for three times as indicated.
Step5. Press the Match button to begin matching the fingerprints of a user whose
fingerprint data has been stored in the system. Press and remove the finger.
Upon successful matching with the user’s stored fingerprints, information is
displayed with a score. When the captured fingerprint image size is 256x324,
a score of 1500 and above ensures a security level with
minimum FAR 1/100,000th and FRR 1/100.
Step6. Press the Match button again to match the fingerprints by pressing
another finger which is not enrolled. Upon failed match, information is displayed
with a low score.

7. How to Use Your Fingerprint Reader?
For best results:
Why the image quality is important?
Startek fingerprint recognition technology is based on minutiae-only: the unique
feature points of a fingerprint. After a fingerprint is scanned, minutiae are extracted
and processed into a template that will be used for biometric enrollment and
matching. If the scanned fingerprint is unclear or does not have enough contrast,
the minutiae may be inconsistently sampled, resulting in less accuracy and poor
performance. Certain environments and skin conditions, such as wet or dry skin,
can initially cause a fingerprint to appear too light or too dark.
Proper placement is the key to good results?
Startek fingerprint extraction algorithm is capable of extracting the correct minutiae
even without benefit of a perfect print. However, the proper placement of your
finger while scanning can help give more consistent results for any biometric
application. The suggestions below will help you get the best quality fingerprint to
ensure better performance and reduce the chances for failure to enroll or match
correctly.
8. How to scan your finger?
Place the pad of your finger at the center of the sensor
The pad is the fleshy part of the finger, located in the middle of the first segment.
Place the pad (not the tip) such that it covers the sensor area with maximum
contact. Be sure that the core of the fingerprint is scanned.

Try to match the fingerprints by rotating 30 degree on the sensor area or to
exceed the sensor area. Upon successful matching with the user’s stored
fingerprints, information is displayed with a score. However, the score you get
is expected to be lower than the one you press it normally because there are
fewer minutiae points captured.
