OPERATING THE FINGER SCANNERS

7.2.1

FUNCTION OF THE FINGER SCANNER

ekey finger scanners are exclusively equipped with line (swipe) sensors. To capture a fingerprint, please

draw your finger over the sensor. The system records the image of the fingerprint lines (papillary lines)

line by line and compiles an image from the individual rows. The finger scanner then calculates a

recognition template (minutia and their relative positions), which is compared to the previously stored

finger templates (reference finger templates). If a certain degree of congruence is exceeded (threshold), a

positive match (= finger was recognized) will trigger an allocated action (e.g. switch relay output 1). It is

important to note that no fingerprint images are stored.

Which part of the finger should be recorded by the finger scanner?

It is necessary to capture an image of the 3rd

phalanx. On the contrary, your finger scanner will not

function properly.

In order to ensure this, take care to operate the finger

scanner correctly. It is fundamental to place your

finger correctly in the finger recess and move it down

across the sensor at the right speed. Ergonomically

speaking, the best fingers are the index, the middle

finger and the ring finger. The thumb and the little

finger may not be used!

A finger scanner works like a camera. It makes a picture of the bottom side, the papillary lines, of your

finger´s third phalanx. However, this picture must be of good quality, so that physical access can be

granted whenever necessary.
