- penetrated: the signal can go through the metal glass film. Driver can open the barrier with the card inside car without lowing down window by automatic identifying system;
- directive: the system works under dual-mode by infrared position rf with strict requirement on direction and stability. It will not work without angle of 60 degree;
- stable: the system adopts multi-environmental rf technology to adjust signal data automatically;
- applicable: the are reading sensor can work under diversified environment to choose, such as outside working mode for open parking area and ETC system and inside working mode for underground parking area;
- anti-disturbing: the card reader adopting one more technology and code division multiple access technology with good anti-disturbing ability;
- environmental: the card reader and electrical tag has no electric radiation so it will cause no harm to body;
- low temperature bearing: the card reader can keep temperature with infrared and signal will not be reduced;
- capable: the card reader has multi-data transmission methods which is capable of present control system;
- less maintenance: industrialized, light-proof, protection on each step, all day working and no maintenance.
