3. Operation
Normal operations consist of sending the events that occur to the Host. Normally, these
will be linked to a user ID. The user can simply put his or her finger on the biometric
sensor or start the identification by presenting the card or pressing any key. From hereon,
the Host will launch the identification and save its result. Once the identity of the person
is known, it will be possible to act on an access relay, display a personalised message on
screen or even ask for a code using the keycard.
An aspect that deserves special attention is the possibility to carry out 1:1 identification
with the help of a Clock&Data or RS-232 reader, as indicated in
3.1. FingerVein sensor operation
FingerVein VIM allows for several types of use:
• 1:N Identification: the user places his or her finger on top of the biometric sensor.
An optical barrier activation event occurs, after which the Host orders the capture
of the user's fingerprint. The sensor compares it with all the fingerprints in the
database of up to 1,000 users.
• 1:1 Identification: the user is identified using the card or by entering a code. The
Host receives the identification code and retrieves the corresponding
identification code from its database. This fingerprint is sent to the biometric
sensor, after which the sensor itself scans the user's finger to check its identify
with a 1 to 1 comparison (“Instant Matching”).
The FingerVein VIM is controlled through elemental instructions integrated in the
Active-X Kimaldi Bio-OCX.
3.2. Others
All the aspects related to the operating and connectivity of FingerVein VIM electronics
can be configured as explained in
chapter 7.: “FingerVein VIM configuration”
.
It also incorporates a function for diagnosing faults in the hardware and for remote
firmware updating.
3.2.1. Start-up process
When the FingerVein VIM starts, it will in turn initialize the FingerVein biometric
sensor. This process takes approximately 8 seconds, during which both green and red
LEDs are switched on. After successful completion of the initialization process, red and
green LEDs turn off, and yellow LED remains indefinitely on.
