The V-PASS
The V-PASS is similar to the VeriProx and VeriFlex, but no Wiegand input device
is required. The V-PASS will automatically detect when a finger is placed on the
sensor, compare that fingerprint with all currently enrolled fingerprint templates
and determine if there is a match. A typical operation is described below.
•
The V-PASS top LED is yellow to indicate it is ready for a finger.
•
A user initiates the action by placing their finger on the fingerprint sensor.
•
The User should place the correct finger on the scanner using the Bioscrypt
Ridgelock.
•
The V-PASS will recognize that a finger has been placed and will take an
image of that finger’s print.
•
The amber light will turn off, signaling that the image has been scanned and
the finger can be removed.
•
The scanned image is compared with
ALL
enrolled templates in the
memory of the V-PASS (maximum of 200).
o
If the verification is positive, the top LED will glow green and the unit
will emit an audible beep.
o
If the authentication fails, the LED will glow red and no beep will be
generated.
•
When authentication is successful a Wiegand string can optionally be sent
out for use by a standard door controller.
The V-PASS has several communication options . It is equipped with both a Host
port and an auxiliary port. The Host port may be configured to operate in RS-232
mode or RS-485 mode. The auxiliary port is always set to RS-232. The Host port
connections are made through the wiring pigtail on the back of the reader. The
auxiliary port is accessed from an RJ-11 jack that is hidden under a door on the
bottom of the V-PASS. This door is held shut with a security screw.
The V-PASS can be used as a stand-alone reader or multiple units can be
configured on an RS-485 network. The manner in which you choose to install the
V-PASS will determine which communications settings are most convenient for
your configuration. Certain administrative functions are common to any
installation. You must have a way to “enroll” users into the system, that is, you
must be able to associate their fingerprint data with a specific Wiegand ID number.
You must have a way to distribute this user information to all other readers in your
installation. The VeriAdmin Management Software is provided for this purpose.
