Electronic ID cards (eID) represent the trend of traditional identity documents transitioning to digital. An increasing number of countries are launching or upgrading their electronic identity systems.
Key Features

- Verifier - Service that verifies credential authenticity
Application Scenarios
- Academic degrees and professional certifications
