HJP is an internationally renowned consultancy firm for the planning, procurement and approval of smart card–based ID systems. Using sophisticated model-centric methodologies and tools for requirements engineering, we help our clients to analyze, specify and visualize complex system architectures more efficiently. Since 2003, our experts have played a key role in the planning, procurement, project management and final acceptance of several large-scale electronic ID implementations in Europe, the Middle East and Africa. The projects covered e-passports, national ID and e-health cards as well as e-government and border control solutions. Aside from smart card–based ID systems, HJP Consulting has recently explored smart card–based energy management systems, e.g., for smart homes.
