Protech Systems developed a self-payment kiosk with a modular design that enables customers to choose their own modules for their industry. The main concept for the self-payment kiosk is a sturdy computing terminal supported by a strong base and a slim shape body. This allows the kiosk to be separated into a smaller unit if certain functions are not required, such as the bill and coin module, and enables installation into areas with limited space. In order to match different market demands, all the modules are optional to create a versatile solution.
