Matching
New user matching is implemented by way of
the "CAR" menu in the multimedia interface
(MMI) and can be performed for four users.
A maximum of 5 fingers can be matched per
user.
The MMI provides user prompting for the
matching process to ensure optimum image
quality.
Finger matching is performed by placing it on
the sensor three times in succession with
moderate pressure (< 12 N). The first time, the
finger should be placed in normal centre
position, then approx. 2 mm to the left and
finally 2 mm to the right.
Further prints may be necessary depending
on image quality. If this is the case, the user
will be informed by way of an appropriate
prompt in the MMI.
Three finger images must be read in and
stored before a person can be identified.
At least one finger must be matched.
To rule out identification problems, it is
however appropriate to match two or several
fingers.
