About

The Age Verification (AV) iOS app is part of the Age Verification Solution Toolbox and serves as a component that can be used by memberstates, if necessary, to develop a national solution and build upon the building blocks of the toolbox.

This iOS app is forked from EUDI iOS Wallet reference application, which is built based on the Architecture Reference Framework and aims to showcase a robust and interoperable platform for digital identification, authentication, and electronic signatures based on common standards across the European Union.

The Age Verification (AV) iOS Implementation is based on a modular architecture composed of business-agnostic, reusable components that will evolve in incremental steps and can be re-used across multiple projects.

The AV iOS is the application that allows users to:

  1. Obtain, store, and present an age verification attestation.
  2. Share the proof of age attestation with online services to gain access.

Development

Specifications Employed

The app consumes the SDK called EUDIW Wallet core Wallet Kit and a list of available libraries to facilitate remote presentation and issuing test/demo functionality following partially the specification of the ARF, including:

  • OpenID4VP - draft 24 (remote presentation)

  • OpenID4VCI draft 15 (issuing)

Build

Whether you cloned or downloaded the 'zipped' sources you will either find the sources in the chosen checkout-directory or get a zip file with the source code, which you can expand to a folder of your choice.

In either case open a terminal pointing to the directory you put the sources in. The local build process is described here and the configuration options are described here.

Testing

To test the app, there is an issuer and verifier service available online. This allows you to perform the enrollment directly from within the app or via the online issuer in order to receive a proof of age attestation. With the verifier, you can then present this attestation.

  • Issuer functionality, to support development and testing, one can access an OID4VCI test/demo service for issuing at: Age Verification Issuer

  • Relying Party functionality: To support development and testing, one can access a test/demo service for remote presentation at: Age Verification Verifier

Important note

This white-label application is a reference implementation of the Age Verification solution that should be customised before publishing it. The current version is not feature complete and will require further integration work before production deployment. In particular, any national-specific enrolment procedures must be implemented by the respective Member States or publishing parties.

Please note that this application is still under active development. It is regularly updated and new features and improvements are continuously being added.
