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 directly 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
