Card4B develops and operates Integrated Mobility solutions through interoperable contactless ticketing software, passenger interaction, embedded systems and smartphones, systems integration and business intelligence. A team with nearly 20 years of experience and R&D provide a vision on how to offer ATFC systems based on Interoperability and Integration Software Frameworks, both for back-office and equipment, providing independency from the equipment and customer-media supporting any card technology. Our solutions are based on modular software components, for mobility and multiservices (e.g. Bus, Train, Tram, Underground, Parking, Tolls, Tourism, Schools, Taxis, ATM, MNO). The same Ticketing Kernel (TK) software can be used in all equipment, from Classical (e.g. validator) to new generation (e.g. smartphone), by all Ticketing Applications to dialogue with all media.
