This document delineates the workflow for essential functionalities of Inji Wallet.
After installing the application for the first time, the user will be asked to set up unlock method for it. The app supports biometric or PIN-based locks. For more details, refer to the .
Residents have the ability to download a Verifiable Credential (VC) for themselves, their family members, or friends using a single mobile device. This can be done through two methods:
While downloading the VCs, the credentials are validated and verified for the authenticity of the issuer using the signature and the proof type provided in the VC.
Downloading VC using OpenID for VC Issuance Flow (eSignet)
Below sections are going to detail as how Inji Wallet as an OIDC client to OpenID4VCI method of downloading a VC and illustrated implementations.
Download credentials using UIN / VID:
Download credentials using Knowledge Based Identification (KBI)
Appendix:
The term “identifier” in the architecture diagram refers to the unique identifier which can be used to download the credential on the esignet login Page
eSignet supports Various types of authorizations, ACR value is configured based on the Issuers' need to include the authorization mode in the authorization page
Types of Authorization Supported for Credential Download by eSignet are:
Login With OTP: Credential download using OTP Based authentication to authorize the user
Illustrated Implementation: National ID credentials download
Login With KBI: Credential download using KBI to authorize the user. The knowledge (as described by the credential issuer to authorize) is exposed to eSignet from Registry (Issuer) through eSignet Issuance Plugins
Illustrated Implementation: Insurance ID credentials download
Residents can use Inji Wallet to log in to any service provider app (integrated with e-Signet) by just scanning a QR code from their portal.
The app performs offline face auth after scanning the QR code to verify the user's presence.
Once the presence is verified, the resident is given the option to choose the optional information to be shared with the service provider portal.
After consent is provided, the app sends a WLA (Wallet local auth) token which is a JWT token to the relying party.
The resident is then given the access to the portal after the token verification.
From Settings screen, users can access Backup settings screen. In Backup settings screen, users can configure their preferences for data backup. The setting, configured once during the application's lifecycle, determines whether Google Drive or iCloud will be utilized based on the device platform. To restore backup data to the mobile wallet, users must log in to the same account and configure settings within the app accordingly. Additionally, restored Verifiable Credentials (VCs) should be re-activated to enable QR Code login functionality.
This method of VC download illustrates the OpenID4VCI method of download using UIN / VID issued to the resident. In this, eSignet plays the authentication and authorisation end point to connect to the credential provider (Reference Implementation: MOSIP).

The credentials are shared in a peer-to-peer model with the verifier application. The data exchange between devices is done using the BLE Protocol. For more information, refer to documentation.
