Onboarding Screen Components

The Mobile SDK provides pre-built React Native screen components for the identity verification onboarding flow. These screens handle the UI and logic for document selection, camera scanning, and user interactions.

Import Pattern

Screens are imported directly from their onboarding paths, not from the main package index:

import { DocumentCameraScreen } from '@selfxyz/mobile-sdk-alpha/onboarding/document-camera-screen';
import IDSelectionScreen from '@selfxyz/mobile-sdk-alpha/onboarding/id-selection-screen';
import SDKCountryPickerScreen from '@selfxyz/mobile-sdk-alpha/onboarding/country-picker-screen';

Provider Requirement

⚠️ All screens must be wrapped in SelfClientProvider. The screens use useSelfClient() internally and will throw an error if used outside the provider context.

Available Screens

DocumentCameraScreen

Handles MRZ (Machine Readable Zone) scanning from identity documents using the device camera.

import { DocumentCameraScreen } from '@selfxyz/mobile-sdk-alpha/onboarding/document-camera-screen';

<DocumentCameraScreen
  onBack={() => navigation.goBack()}
  onSuccess={() => navigation.navigate('NFCScan')}
  safeAreaInsets={{ top: 44, bottom: 34 }} // Optional
/>

Props:

  • onBack?: () => void - Called when user taps back button
  • onSuccess?: () => void - Called when MRZ scan succeeds
  • safeAreaInsets?: { top: number, bottom: number } - Safe area padding

Behavior:

  • Displays camera viewfinder with MRZ scanning overlay
  • Shows scan instructions and animations
  • Automatically processes MRZ data when detected
  • Emits DOCUMENT_MRZ_READ_SUCCESS or DOCUMENT_MRZ_READ_FAILURE events
  • Provides haptic feedback during scanning

IDSelectionScreen

Displays available document types for a selected country and handles document type selection.

import IDSelectionScreen from '@selfxyz/mobile-sdk-alpha/onboarding/id-selection-screen';

<IDSelectionScreen
  countryCode="USA"
  documentTypes={['p', 'i', 'kyc']} // p = passport, i = ID card, a = aadhaar, kyc = KYC flow
/>

Props:

  • countryCode: string - ISO country code (e.g., “USA”, “GBR”)
  • documentTypes: string[] - Available document types for the country

Behavior:

  • Shows document type cards with icons (passport, ID card, Aadhaar, KYC, etc.)
  • Handles document type selection
  • Emits DOCUMENT_TYPE_SELECTED event with selected type and country
  • Provides visual feedback for selections

CountryPickerScreen

Displays a searchable list of countries for document selection.

import SDKCountryPickerScreen from '@selfxyz/mobile-sdk-alpha/onboarding/country-picker-screen';

<SDKCountryPickerScreen />

Props:

  • No props required - manages its own state internally

Behavior:

  • Shows searchable country list with flags
  • Filters countries by name as user types
  • Loads available document types for each country
  • Emits DOCUMENT_COUNTRY_SELECTED event with country info
  • Optimized for performance with large country lists

Screen Flow Example

A typical onboarding flow might look like:

CountryPickerScreen
    ↓ (DOCUMENT_COUNTRY_SELECTED)
IDSelectionScreen
    ↓ (DOCUMENT_TYPE_SELECTED)
DocumentCameraScreen
    ↓ (DOCUMENT_MRZ_READ_SUCCESS)
[Your NFC Scanning Screen]

Error Handling

Screens handle errors internally and emit appropriate events. Listen for failure events in your event listeners:

addListener(SdkEvents.DOCUMENT_MRZ_READ_FAILURE, () => {
  // Navigate to error screen or retry flow
  navigation.navigate('DocumentScanError');
});
