Contactless Bus Validator

The validator is mounted on a handrail in the passenger compartment of the bus; it is equipped with a 4.5inch color display, contactless card reader and wireless Internet connection. A system of passive cooling and electric heating was implemented for quick start in frosty weather. We made a deep redesign of the validator. The new solution was implemented on the Mediatek platform with a custom display, battery and all the necessary peripherals. In addition, an update of the operating system and payment application by air was implemented. We implemented a passive cooling and electric heating system for quick startup in frosty weather.
