DC Mobile SDK Overview

What This SDK Is

The Digital Credential Mobile SDK is a modular identity platform for building trusted digital identity experiences in mobile applications.

At a high level, it helps teams:

onboard and enroll users into digital credentials,
manage credential lifecycle and wallet data on-device,
perform secure authentication and data-sharing flows,
support in-person and remote verification journeys,
keep credentials and cryptographic material up to date over time.

This overview is intentionally API-agnostic and designed for product and engineering evaluation.

Core Value Proposition

The SDK enables organizations to launch digital identity use cases with a consistent user experience, strong security defaults, and flexible integration patterns.

It is designed to reduce custom implementation complexity across:

identity proofing and enrollment,
credential lifecycle management,
consent-based data sharing,
authentication orchestration,
in-person verification interoperability.

Feature Map

1. Enrollment Orchestration

End-to-end enrollment flow coordination.
Support for resumable journeys (continue interrupted enrollment safely).
Flexible flow composition using plugin-based enrollment steps.
Configurable user interaction points for branded enrollment experiences.

2. Document And Identity Evidence Capture

Document capture and validation capabilities through dedicated enrollment plugins.
Support for document-side capture flows (for example front/back capture patterns).
Optional remote document capture session support.
MRZ and NFC-assisted document processing paths for supported evidence types.

3. Pin, Face And Liveness Verification

PIN creation, update and verification can be used to protect request management and wallet access.
Face capture and face matching as enrollment building blocks.
Liveness-oriented challenge/response options to strengthen proof-of-presence.
Local and remote capture journey support depending on configured flow.

4. Binding And Verification Channels

Phone binding plugin support for verified phone ownership workflows.
Email binding plugin support for verified email ownership workflows.
OTP-oriented enrollment steps where required by business policy.

5. Credential Wallet And Lifecycle

On-device wallet abstraction for credential storage and retrieval.
Support for multiple credential states (for example active, pending, failed).
Credential removal/disenrollment capabilities.
Lifecycle events and status propagation for app-level orchestration.

6. Online Requests, Authentication, And Messaging

Notification-driven request handling model for online interactions.
Online authentication request sessions.
Request acceptance/decline handling with eligible credential selection.
Ad-hoc message and event-style notification support.

In-person attribute sharing support aligned with ISO 18013 flows.
Offline and online session modes for verifier connectivity models.
Request/consent/transfer model for controlled attribute disclosure.
Transfer progress and session lifecycle callbacks.

8. Digital Credential Extensions (Platform-Dependent)

Digital credential context support for modern OS-level wallet/extension scenarMobile.
Shared context management for host-app and extension interoperability.
Registration/unregistration utilities for eligible digital credential providers.

9. UX, Branding, And Localization

Theme module for UI consistency and brand adaptation.
Reusable UI components for enrollment and identity workflows.
Localization-ready resources for multilingual deployments.
Integrator control points for custom screens in critical journey steps.

10. Operational And Integration Readiness

Modular packaging across core, theme, cryptography, enrollment plugins, and in-person sharing.
Push-notification compatibility for asynchronous lifecycle updates.
Deep-link handling support for continuation flows.
Release-note based evolution model supporting ongoing integrator upgrades.

Modular Components (Conceptual)

MobileIDCore: core orchestration, enrollment engine, wallet, notifications, status and update flows.
MobileIDTheme: default UI/theming primitives and reusable visual components.
MobileIDCryptography: cryptographic support layer.
MobileIDEnrollmentPlugin*: optional enrollment capabilities (document, face, phone, email, etc.).
MobileIDInPersonSharing: ISO 18013-aligned in-person sharing and transfer flows.

Expected Outcomes For Integrators

Faster delivery of digital identity features with less custom security plumbing.
Consistent user journeys across enrollment, authentication, and sharing.
Stronger maintainability through modular capabilities and lifecycle tooling.
Easier evolution toward new trust and digital credential ecosystems.
