The implementation of the Nha Card digital certificate, based on Blockchain technology, will reinforce and consolidate the government interoperability platform, benefiting and boosting the entire innovation and digital transformation ecosystem in the country, especially in the health sector.

The Nha Card integrates other systems, such as the National System of Identification and Civil Authentication and the Health Information System. It allows accelerating the process of automation, dematerialization, and "securization" of various health documents, currently available in physical format, such as vaccination cards, prescriptions, and patient medical records, among others.
