Main Functionalities of the Wallet

QR Scan Functionality

• General Use:

  • The QR Scan function is used to scan QR codes provided by a third party, which can trigger processes for obtaining or presenting credentials. To initiate a scan, press the 'Scan QR' button to deploy the camera.

    

• Scanning Process:

  • After pressing the 'Scan QR' button, align the QR code within the camera to scan it. This will trigger the specific process linked to the QR code.

Credential Issuance Process

• PIN Verification:

  • If the credential issuance process includes PIN verification (used for additional security), you will be prompted to enter a PIN after scanning the QR code, that you have received through a communication channel specified by the issuer.

    

Manual Intervention for Credential Signing

• Signing Process:

  • For credentials that require manual signing, you will initially receive them in an 'unsigned' state. If you attempt to obtain the signed credential before it is ready, a notification will appear stating that the credential is not ready for signing yet.

    

  • Once notified that your signed credential is ready, use the 'Sign' button in the wallet to finalize the credential.

    

Credential Presentation Process

• Automatic Credential Display for Specific Types:

  • When required to present a credential, the wallet automatically displays all available credentials of the type required for the transaction or verification. Select the appropriate credential you wish to present and confirm the action. If the presentation is successful, a confirmation pop-up will appear, indicating a successful transaction or verification.

    

Credential Deletion

• Deleting a Credential:

  • If you choose to delete a credential, simply press the trash icon on the credential. Be aware that once a credential is deleted, it cannot be recovered, so you must obtain a new one through the issuance process if needed.

    

Language Settings

• Changing Language:

  • You can change the language of the wallet interface by going to the settings and selecting your preferred language. Currently, the wallet supports English, Spanish, and Catalan.
