Refugee crises are unfolding amid increasingly intensive use of information and communication technologies. Mobile phones are indispensable digital companions to many displaced people. Humanitarian organizations use biometrics, database and mobile payment systems, and artificial intelligence, aiming to streamline their services, enhance accountability and reduce costs. These technologies have arguably improved refugees’ lives, and by some measures, improved assistance, but they can also generate harms. Understanding the latest digital developments is critical for humanitarian leaders, public policy makers and academics in managing their shared responsibility of protecting refugees and internally displaced people.
