According to a paper by the World Bank, patient identification can be critical in imparting fast and effective healthcare services to patients and can do wonders for public health management, thereby helping achieve sustainable development. Digital identity verification systems can assist healthcare providers to not only to improve the quality of healthcare they provide but would also enable them to improve organisation and sharing of medical records, ensure insurance claims and reduce medical fraud by protecting patient data.
