Both the tracing apps and early vaccine passports are trends in the right direction. However, consumers need a unified way to not only prove who they are, but provide credentials to prove their claims, such as a vaccination status depending on the jurisdiction they are in. To do this, consumers need digital identity and document verification services that are cross-border and can be easily adopted.
This requires a horizontal identity layer that is not tied to one industry vertical and has cross-platform support for rapid adoption. As vaccinations continue at different rates in countries, individuals will need to prove again and again their vaccination status for everything from international flights to local concerts. Both the continued dependence on digital services and the need for identity verification will pave the way for Self-Sovereign Identity (SSI).
