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 (...).

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:

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

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.

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.

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.

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:

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.
