Concepts of Operations
The VeriProx
The VeriProx integrates an industry-standard proximity card reader with
Bioscrypt’s MV1100 fingerprint verification technology. A typical operation is
described below.
•
A user waves the proximity card near the front of the VeriProx.
•
The ID number is read from the internal proximity card reader.
•
The ID is transferred to the MV1100.
o
If the ID is invalid, the LED on the top of the VeriProx will glow red.
o
If the ID presents a valid previously enrolled template, the LED on
the top of the reader will glow amber; indicating the user should
place their finger on the sensor on the top of the reader.
•
The User should place the correct finger on the scanner using the Bioscrypt
Ridgelock.
•
The amber light will turn off, signaling the finger can be removed.
•
The scanned image is compared with the data that is stored under the ID
number in the memory of the VeriProx.
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 that contains the site
code and ID number read from the proximity card is sent out for use by a
standard door controller.
•
Optionally, the VeriProx can be configured to send out a pre-determined
“failure” ID whenever an unsuccessful verification occurs. An additional
option allows the site code to be replaced with another number.
The VeriProx 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 VeriProx. This door is held shut with a security screw.
