EFKON introduced its infrared-based toll collection system to Malaysia in 1999. By 2004, it had replaced the microwave-based electronic toll collection systems nationwide.

One reason is the better performance of the infrared technology from EFKON compared to the microwave-based solution, as the metal-coated windshields in Malaysia require a high-performance communications solution. This allowed EFKON to successfully expand its market leadership in Malaysia and sell several million OBUs and other tolling systems in this market. The On Board Units are built into vehicles to allow automatic tolling in a toll or fee collection system.
