"Semi-active" means that RF energy 'excites'
the transponder and initiates the battery boosted
response. This type of operation preserves bat-
tery life — an important consideration in all
wireless transmission.
The vehicle identification system has three
modes: continuous transmission of the tag ID
(default); activation by user; and random trans-
mission of the tag ID. Both reader and tag use a
16-20 bit password which are required to match
to result in an output from the reader. The reader
reads the encoded data from the tag and trans-
mits the data back to the host system, providing
an audible and visible LED indication of a prop-
erly read tag. Further, each reader in the system
operates on a factory-set frequency offset from
frequencies being used by other readers in the
system, allowing operation of multiple readers in
close vicinity of each other without interference.
Their "Booster" in-vehicle transponders are
a smart combination of transponder and card
reader. They read normal access control cards in
the vehicle and send both driver information and
vehicle information to the reader and from there
on to the access control system, thus enabling
authorization of both vehicle and driver. One ver-
sion supports AES encryption.
With technology originally developed for the
Autobahn, vehicles can be travelling at speeds
up to 125 mph and information is still read,
although an employee driving that fast will likely
soon be surrendering his credentials! It is worth
noting that the capabilities of enhanced security
from dual-ID technology and high-speed reads
— originally intended for toll road applications
— offer rather effective asset tracking when
combined.
"While we often see the use of RF technology
in access control applications, the potential for
use lies well beyond that. When properly applied,
it can be employed for fleet management, asset
tracking, time and attendance, operational effi-
ciency enhancements and various other benefits,"
explains Craig Wilson, Nedap's Marketing Direc-
tor. "It really just relies on a solid understanding
of the capabilities and limitations of the technol-
ogy as applied with creative design."
It is clear that wireless technology is growing
in today 's security installations. Cer tainly,
pro ducts s uch as thes e des er ve the time
investment to develop a solid understanding of
their capabilities. ■
