RF IC for Electronic Toll Collection System

Electronic toll collection system (ETC) allows non-stop payment on expressways. Our RF ICs can be used for wireless ETC in Japan, China, and South Korea.
Since both onboard equipment and road side equipment can be used, you can use not only for a expressway but for the tollgate for parking systems, etc.
