Users can view the activity logs of a VC from the Home Page or the detailed view by choosing the menu option "View Activity Log" from the quick access menu (...).

Credential Sharing Methods

Pre-requisites

• Two or more devices with Inji Wallet installed are required to share credentials. The relying party's phone should be an Android device.

• All required permissions like Bluetooth, location, and camera access are enabled on both devices.

• The parties involved are usually a Resident (sharing party) who wishes to share their credentials with a Relying party (receiving party), a banker, a health worker, or other professional service.

Users can now share their credentials using any of the methods listed below:

1. Share option from the NavBar.

2. Share or Share with Selfie option from the quick access menu (...) from a VC in the Home Page

3. Share or Share with Selfie option from quick access menu (...) in detailed view of VC.

Let us understand the process of sharing credentials using an example and see the step-wise process for all the above three methods. Suppose a Resident wishes to share their credentials with a Relying/ Requesting party through the receiver's phone, the following steps outline the procedure for both parties involved:

Share from Share Option in NavBar

On the Sharing Party's phone:

• The resident opens the QR Code Scanner by clicking on the Share button in the NavBar. The application now prompts for permissions.

• Upon granting the necessary permissions, the app opens a camera where the resident can scan the QR code of the recipient's (Verifier/Relying Party) phone.

• Once the QR code is successfully scanned, both phones will establish a Bluetooth connection.

• The resident then needs to choose a downloaded VC and select either the Share or the Share with Selfie option.

• The Share button will solely share the VC, while the Share with Selfie option will verify if the sender's face matches the photo in the VC before proceeding to share.

On the Relying Party's phone

• This functionality is only available on Android devices. To access it, the receiver needs to navigate to the settings page and locate the Receive Cards option.

• On selecting this option, it will open the QR code page. For the relying party to be able to receive a card, the resident needs to scan the QR code using a shared phone. Once the QR code is scanned and shared, the relying party will receive the VC and be able to preview its contents.

• To view the received cards, they would need to access the settings page and find the Received Cards section. Clicking on this section will display the received cards. If the receiver has not received any card, this section will be empty.

• Please note that the relying party can only view the received cards and will not be able to share or perform other actions with them.

Share / Share with Selfie from Home Page Quick Access menu

On the Sharing Party's phone:

• The resident clicks on the quick access menu (...) from a VC on the Home Page and chooses the Share or Share with Selfie option from the menu.

• The application now prompts for permissions if not granted already.

• Upon granting the necessary permissions, the app opens a camera where the resident can scan the QR code of the recipient's (Verifier/Relying Party) phone.

• Once the QR code is successfully scanned, both phones will establish a Bluetooth connection.

• The Share button will solely share the VC, while the Share with Selfie option will verify if the sender's face matches the photo in the VC before proceeding to share.

On the Relying Party's phone:

• This functionality is only available on Android devices. To access it, the receiver needs to navigate to the settings page and locate the Receive Cards option.

• On selecting this option, it will open the QR code page. For the relying party to be able to receive a card, the resident needs to scan the QR code using a shared phone. Once the QR code is scanned and shared, the relying party will receive the VC and be able to preview its contents.

• To view the received cards, they would need to access the settings page and find the Received Cards section. Clicking on this section will display the received cards. If the receiver has not received any card, this section will be empty.

• Please note that the relying party can only view the received cards and will not be able to share or perform other actions with them.

Share with a selfie from VC Detailed View Quick Access menu

On the Sharing Party's phone

• The resident clicks on the VC on the Home page and clicks on the quick access menu (...) in the detailed view. Resident can choose either Share or Share with Selfie option from the menu.

• The application now prompts for permissions if not granted already.

• Upon granting the necessary permissions, the app opens a camera where the resident can scan the QR code of the recipient's (Verifier/Relying Party) phone.

• Once the QR code is successfully scanned, both phones will establish a Bluetooth connection.

• The Share button will solely share the VC, while the Share with Selfie option will verify if the sender's face matches the photo in the VC before proceeding to share.

On the Relying Party's phone:

• This functionality is only available on Android devices. To access it, the receiver needs to navigate to the settings page and locate the Receive Cards option.

• On selecting this option, it will open the QR code page. For the relying party to be able to receive a card, the resident needs to scan the QR code using a shared phone. Once the QR code is scanned and shared, the relying party will receive the VC and be able to preview its contents.

• To view the received cards, they would need to access the settings page and find the Received Cards section. Clicking on this section will display the received cards. If the receiver has not received any card, this section will be empty.

• Please note that the relying party can only view the received cards and will not be able to share or perform other actions with them.

Verifiable Credential Sharing & Presentation via OpenID4VP

Note: Screenshots will be added soon to enhance the user experience and better explain the steps shown below.

Cross-Device Flow (OpenID4VP)

This method is used when you're using Inji Wallet on a mobile phone and the verifier (e.g., a service provider or kiosk) is using a separate device such as a laptop, tablet, or scanner.

Steps to Present Credentials:

1. Verifier generates a QR code on their system/portal requesting specific credentials.

2. On your Inji Wallet, tap the QR scanner icon from the home screen or use the “Share” option.

3. Scan the QR code displayed by the verifier.

4. The wallet reads the verifier’s request and shows you a list of matching credentials.

5. You are prompted for face authentication.

6. Choose the credentials you want to share.

7. Tap “Share” to proceed. The wallet sends the Verifiable Presentation (VP) to the verifier securely.

8. You’ll see a confirmation message once the sharing is complete.

Same-Device Flow (OpenID4VP)

This method is useful when you’re accessing a portal from the same mobile device that has the Inji Wallet installed.

Steps to Present Credentials:

1. On your phone browser, visit the service portal that is requesting your credentials.

2. Tap on the “QR Code” or similar button.

3. This opens a deep link that launches your Inji Wallet app automatically.

4. The wallet fetches the verifier’s request.

5. A list of matching credentials is displayed.

6. You will be asked for face authentication.

7. Choose the credentials to be shared.

8. Tap “Share”.

9. You are automatically redirected back to the service portal (Android).

   • On iOS, you may need to manually switch back to the browser.

Pinning a VC

After clicking on the ellipsis button on the downloaded VC, a button will appear allowing for the VC to be pinned. Selecting this option will pin the specific VC to the top of the screen.

Activating a VC

There are two ways to activate the VC:

• The second option is to click on the "Activate for online login" menu option by clicking on the quick access menu (...) of the card from the detailed view of the VC.

• A confirmation alert message will be prompted upon clicking the "Activate for online login" option. Once permission is granted, the user will be directed to an OTP screen. After entering the correct OTP, the VC will be activated and projected on the screen with the same message.

Deleting a VC

There are two ways to remove/delete a VC from the wallet:

• The first option is to click on the Remove from Wallet menu option from the quick access menu (...) of the card from the Home Page.

• The second option is to choose the Remove from Wallet menu option from the quick access menu (...) of the card from the detailed view of the VC.

• Upon clicking this option, the user will be prompted with a pop-up for confirmation. If the user chooses, “Yes, I confirm” the VC will be removed from the wallet.
