3. Operation
Thanks to its IP connectivity, FingerVein Online electronics makes it possible to install a
network of biometric sensors or different types of card readers, accompanied by the
corresponding actuators or user interfaces. All the peripherals are Host-managed, except
for the biometric search engine, which is housed inside the FingerVein sensor itself.
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 Online electronics 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 sensor is controlled through elemental instructions integrated in the
Active-X Kimaldi Bio-OCX.
3.2. Connection to a configurable RS-232 reader
Kimaldi Electronics offers a series of readers (for example, KRD13M and SC42) that
have automatic operating modes and that also allow for two-way communications
between the Host and the reader (normally for configuration tasks).
FingerVein Online electronics is capable of capturing the events generated by these
readers and applying them with the same treatment as if they came from a Clock&Data
reader: automatic buzzer activation and LEDs and multiread filtering, etc.. These
readings are notified from the
event.
At the same time, two-way communications are permitted between the Host and the
reader from the combination of the
