A small electronic, medium range ID card was developed by “KODINIS RAKTAS“. The SCL card operates on a 2.4 GHz radio band and emits a unique ID code every 2 seconds. It is able to communicate with a receiver up to 5m away from the device, a useful feature for intruder and car alarm systems. RID820 is a user-identification module for MAS-800 and it is able to swap entry/exit time from 0 to 30 seconds when the SCL card is detected. IMB4.2 and IMB5 are car immobilisers with an integrated anti-carjack feature. If the SCL card is not detected by IMB4.2 or IMB5 within 90 seconds of the ignition of the engine, the car will be immobilised.
