There is two sort of transponders used in the immobilizer technique. The first a single is RFID transponder.

Due to the fact the introduction of immobilizer systems the want for improved security regularly increases. Many Anti Theft Systems make use of Radio Frequency Identification (RFID) technology due to its exclusive functions. RFID transponders can supply a high degree of security at low price.

Key-based immobilizer systems consist of four most important components. The core with the technique may be the transponder, a battery less device that's obtainable in different type elements and with diverse functionalities. For operation, the transponder needs to be supplied with energy from an external source. The transceiver generates a high frequency magnetic field which is radiated by an antenna coil. The power activates the transponder and it sends a information stream in type of a modulated RF signal. This signal is demodulated by the transceiver then passed for the controller for data processing.

Second transponder sort: Crypto Transponders

Crypto Transponders are the second generation of transponders for use in immobilizers. The new generation of crypto transponders created by Texas Instruments is based upon the TIRIS TM half duplex RFID technologies and is compatible to all common RF interfaces on the TIRIS TM item range.

What exactly is Standard Safety Architectures working with RFID?

1. Fixed Code Systems

2.Rolling Code Systems

3.Password Protected Transponders

4.Combined Rolling Code / Password Systems
