Tech Lead

Nederlandse Rode Kruis


The Netherlands Red Cross helps to strengthen resilience of vulnerable people exposed to hazards and crisis situations and we respond to disasters and conflicts to save lives and alleviate suffering. In the Netherlands we do this with more than thirty thousand volunteers and internationally through technical assistance, supplies and financial aid. Together we act before, during and after natural and man-made disasters to meet the needs and to improve the lives of vulnerable people.

We do this without regards to nationality, race, religious beliefs, class or political opinion. Our seven principles guide our humanitarian work: humanity, impartiality, neutrality, independence, voluntary service, unity and universality.

510 is the data initiative of the Netherlands Red Cross. Our vision is that smart use of data will help towards faster, higher quality and more (cost) effective humanitarian aid at a global level. The 510 initiative was established early 2016 and has grown since into a team of 23 core and project staff, 20 students and 50 volunteer data experts with diverse backgrounds. The team is developing data and digital solutions for humanitarian aid. Our main results are published on

The Project: 121

510 is researching and developing a system to improve current cash-based assistance in humanitarian aid. We develop a system with a digital identity and cash wallet that can be used to transfer money faster to those affected in a disaster area. With this money, those affected can purchase necessities like food, water and other relief goods. The focus of the research is how technology can make these cash distributions fast, safe and fair. The use of technology can, among other things, reduce the logistical challenges where cash distributions are involved. In parallel, the use of technology has the potential to lower overhead costs and accelerate the aid process. As each digital wallet could be linked to an individual, it will be easier to see who has or has not received aid.
