Gate and Vehicle Solution
Based on plusID identity verification technology
Keep traffic moving while insuring the identity of drivers and vehicles
As the need for heightened security pervades every corner of society new challenges have been
created for the movement of vehicles through gates. Whether it is a port, a military base, or a
logistics center, vehicle traffic is slowed by traditional, manual methods of
verifying driver identity at portals and gates impacting productivity and the
flow of commerce.
Facility operators need to be able to quickly and reliably verify the identity
of drivers and vehicles without imposing solutions that violate privacy, add
substantial costs or create additional security risks for the organization.
An ideal approach would be to have a “fast lane” for drivers and vehicles
that we “know”, enabling them to proceed through checkpoints without
stopping. Conventional manual checks would still be used for the smaller
population of drivers and vehicles that are not pre-qualified.
While it is possible to install RFID technology on a truck for remote
identification of the vehicle, the challenge has been how to verify the
identity of the driver. A known vehicle with the wrong driver could present
as much, or more, of a risk than the presence of a completely unknown
vehicle.
Until now it has not been possible to reliably verify driver identity without
requiring a full stop for either manual inspection of identity credentials or
for execution of a biometric verification at a fixed, mounted reader. The
Privaris plusID Gate and Vehicle system changes that by offering the
world’s first, wireless, personal, biometric identity verification solution.
Personal biometrics
A New Approach
Personal, Mobile Biometrics
for Gate and Vehicle Security
∙ verifies driver identity
without requiring vehicles
to stop
∙ matches driver to vehicle
∙ works with commercially
available physical access
control systems for gate
operation
∙ works with commercially
available solutions for
vehicle starting and locking
∙ cannot be shared, useless
if lost or stolen
With Privaris plusID, drivers verify their identity by swiping their finger on their own key fob
biometric device as they approach the gate. The device compares the live fingerprint to the
fingerprint template securely stored inside their device and upon a match, wirelessly transmits
encrypted credential information (not biometric data) to the gate control system which validates
the access rights for that driver and vehicle.
Easy integration with physical access control systems
The Privaris gate system can be configured to output a Wiegand data stream – a standard
communications signal that is compatible with virtually all access contr ol systems.

Protecting privacy and minimizing corporate risk
The plusID unit eliminates the privacy concerns associated with conventional biometric systems.
The user’s biometric data is never collected or stored in a database. Users enroll dire ctly into their
own personal plusID unit where the data is encrypted and securely stored. It is never released or
transmitted. Rather than delivering biometric data as an access credential, plusID uses it simply
to “unlock” the transmission of standard identity credentials.
This unique approach eliminates employee concerns over the collection of personal data while
eliminating the risk and expense of collecting, storing and protecting employees’ sensitive
personal information.
Convergence: combining physical and network security
plusID provides organizations the ability to use a single device to satisfy both their physical and
logical (network) access needs, for convenient, secure access – everywhere it is required.
In addition to supporting long-range wireless communications over 802.15.4 for gate access,
plusID also works with 125 kHz and 13.56 MHz contactless card readers from HID, Casi, and
Indala for access to multiple buildings and facilities in place of standard access cards (such as
Prox and iCLASS) – no coding, middleware or wiring required. Further, each plusID device can
also be used for logon to computers and networks. It is out-of-the-box compatible with Microsoft
Servers, no middleware required, for use in place of passwords and smart cards.
Technical overview: gate and vehicle application
As the vehicle approaches the gate, the driver swipes their finger across their plusID device. After
verification of the driver’s fingerprint, the plusID transmits credential data via 802.15.4, an IEEE
standard for wireless communications operating at 2.4GHz. The data is received by the Privaris
Long Range Transceiver, which decrypts the credential information and passes it to an external
gate control system, which opens the gate. The entire transaction typically takes less than three
seconds.
The plusID identity token supports wireless communication with the transceiver over distances of
up to 100m (328 feet). With adequate lane design, vehicles can easily proceed through gates at
moderate speed without having to stop the vehicle!
Verification and vehicle speed
Based on the speed of travel and the plusID’s maximum transmission range of 100 meters* (328
feet), below is the amount of time available to turn on the device and successfully verify - while
approaching the gate:
∙ At 10 miles per hour = 22 seconds to verify
∙ At 15 miles per hour = 15 seconds to verify
∙ At 20 miles per hour = 11 seconds to verify
*May vary by installation. Check with Enrollment Administrator for actual range.
Antenna Considerations
The following range testing was conducted with the 50 deg 10.5 dBi outdoor antenna from SMC;
model number SMCANT-DI105, part number 751-5784. There are two other similar 10.5 dBi
antennas from SMC which are the DI135 (36 deg) and the DI145 (26 deg) which are more

directional if this is needed. The 50 deg SMC antenna is recommended this for installations that
are a “generic” single lane.
This antenna in a standard set up was able to communicate at about 25 degrees off center
providing about a 50 degree cone of reception. Like all antennas, there are side lobes that allow
you to communicate in about a 10 foot circle around the antenna with no attenuation. The
approximate pattern is a 10 foot circle around the antenna with a 50 degree beam width beyond
that. The test data was collected using the following criteria:
∙ In a car with all windows rolled up
∙ plusID device held in right hand above dashboard
The baseline was obtained using a standard set-up with no attenuation; the plusID 90 was held
above the dash board at a 45 degree angle and communicated with the lane transceiver with a 23 second delay resulting in a confirmed maximum range of ~300 feet. At 300 feet there is
approximately 250 feet of side to side range as shown in the diagram below. As the distance to
the SMC antenna or attenuation decreases the plusID 90 becomes less orientation and position
dependent as the signal strength increases and provides faster connections time (usually less
than 1 sec).

∙ With 10 dBi of attenuation there was not an appreciable reduction in performance when
measured at the maximum range of 300 feet.
∙ With 16 dBi of attenuation the maximum range was reduced to 90 feet.
∙ With 20 dBi of attenuation the maximum range was reduced to 36 feet.
Based on these measurements it is estimated that 18 dBi of attenuation will give about 50 feet of
range and 15 dBi of attenuation will give about 100 feet of range.
