Biometric Transponder: TRA.FP.INF2

2.0 Overview of function
2.1
Basic information on operation
The Biometric Transponder scans fingerprints using a fingerprint sensor. The finger is dragged
across the sensor, rather than being pressed against it.
The following should be noted:
The fingerprint to be scanned and memorized should always be dragged over the sensor in
the same way.
To do this, place the tip of the finger that is to be stored at the upper edge of the transponder
and draw it across the sensor bar from top to bottom (towards the button) at a constant speed
while applying a slight pressure. The design of the housing means that the finger is guided
properly through the slightly raised side walls.
The fingerprint sensor scans the fingerprint line by line and reassembles it into a complete
image in the integrated processor. If the reassembled image matches the saved image, the
transponder is activated.
2.2 Operating
states
The Biometric Transponder has four different operating modes:
Mode Function
Standby
The transponder is normally on "Standby" in order to save the battery
capacity. After it has completed a function (e.g. scanning), it always
returns to the standby mode.
Learn
In the "Learn" mode, new fingerprints can be memorized. Up to 6
different fingerprints can be saved, two of which are what we call
"administrator" fingerprints. New fingerprints (user fingerprints) can only
be scanned in with the help of an administrator. The only exception is
the scanning of the first two fingerprints (Administrator fingerprints), see
below
Delete
In the "Delete" mode, fingerprints that have been memorized can be
deleted. Individual prints can be deleted, or all fingerprints can be
deleted at once.
Recognise
The "Recognize" mode is the mode before a door is opened. In this
mode, the Transponder is released if a fingerprint is correctly
recognized.
