HAT Data I/O

HAT is a data store. That means that you can read and write any data you want. Be it a passport, your health records or any data you can think of. You can learn more about it here.

HAT API Android has built in support for reading or writing data to your HAT

This section describes the mechanism of writing data. For reading, this is done through data-debits, a system of consented data exchange.
