Triple RFID Protection for Cars
A new car immobilizer system uses three RFID readers to make it tougher
for thieves to drive off with your automobile.
By Claire Swedberg
Jan. 3, 2005To decrease the chances of automotive theft, a new
automobile immobilizer system uses three radio frequency identification
(RFID) readers to make it three-times harder for prospective thieves to
start a car's engine. Released in December by Northland Auto Enterprises,
Burnsville, Minn., the new system, named TheftStopper1, is being sold as
an aftermarket device installed by car dealerships or independent auto
mechanics.
RFID security systems installed in new vehicles by car manufacturers have
succeeded in reducing car thefts, according to statistics gathered by
immobilizer manufacturers. These RFID security systems work by fitting a
car's ignition key with a passive RFID transponder containing a unique ID
code. Whenever the key is inserted into the ignition switch, it activates
an RFID reader connected to a control module in the engine's central
computer (which controls such things as the car's ignition and fuel
systems) and is wired to an antenna built into the vehicle's steering
column. The RFID reader generates a random number, which is transmitted
to the key. The key's transponder combines the random number with its own
unique serial number, encrypts the new number and transmits it back to
the car's RFID reader. If the numbers don't match, the car won't start.

Thieves, however, have found several ways around those systems, according
to Dan Beach, director of new product development for C-Chip
Technologies, a Montreal security systems provider that developed
TheftStopper1. Some experienced thieves can locate the RFID unit,
override it and drive away with the vehicle in a matter of minutes.
Thieves can use a simple resistor to bypass some RFID security systems,
while most factory-installed RFID immobilizers require the use of a
module, in order to "talk" to the onboard computer, Beach says.
Instead of using a passive RFID tag embedded in the ignition key, the
TheftStopper1 system uses a key fob containing an active RFID transponder
that transmits a signal containing a unique ID code over a distance of up
to 20 feet. The key fob is comprised of a miniature OEM transmitter
module powered by a small lithium button battery.
TheftStopper1's three RFID readers each have a nanowatt microcontroller
and relay. One of the RFID readers serves as the starter cutoff,
or "mother," unit. The mother unit controls the power to the two other
control units installed elsewhere in the car. Each of the other two units
functions as a power switch to a different part of the car, such as the
fuel pump, ignition circuit, computer or transmission relay.
When equipped with TheftStopper1, a car won't start unless all three
control units receive a signal from a key fob containing the correct ID
code. Because the key fob's active transponder can transmit its signal
over a distance of 20 feet, the mother unit communicates with the key
fob, well before the driver even starts the vehicle, and verifies that
the key fob's ID code matches the one programmed in the mother unit. When
the driver turns the ignition switch, a second connection is made between
the mother unit and the two other units and the engine starts. Without
the key fob's transponder, none of the three cut-off switches will allow
electric current to flow to their respective devices (the car's fuel
pump, ignition circuit, computer or transmission relay).
For that reason, a thief who manages to hotwire one cut-off switch and
thereby override it, will still not be able to start the car. That's
because the two other units will still lock down the engine without a

R3 ave the above can advise about its advantages/disadvantages?
Are you able to receive the signal within shopping malls?

arrange a demo. They have a sample model. you could check it out at jusco
or you could call him at 012-6358205 (eddy) for more info.
Personally what impresses me is the trasmitter alarm and the ability to
sense pressure/vibration. But then again my concern is the heat that a car
collects during a hot sunny day may damage the device, pressure may also
build up and trigger a false alarm. I guess you could also ask him about
signal reception within shopping mall parking.
despite all of the above i am seriously considering buying one soon. eI $R3 y ` here any others scooter also being curi their battery? or others
