Use the front-facing camera

By default, BlinkID uses the rear-facing camera. For kiosk-style applications where a tablet or similar device is mounted and the user holds their document up to the screen, configure the SDK to use the front-facing camera instead.

Set the front-facing camera

Web (TS)

note

This option is not supported when using the all-in-one blinkid package. Use the camera-manager package and build your own scanning flow using the lower-level API.

Pass preferredFacing: "front" when starting the video stream:

import { CameraManager } from "@microblink/camera-manager";

const cameraManager = new CameraManager();
await cameraManager.startCameraStream({
  preferredFacing: "front",
});

See the camera selection example app for a complete integration example.

Android (Kotlin)

Pass CameraSettings with lensFacing set to CameraLensFacing.LensFacingFront:

BlinkIdCameraScanningScreen(
    blinkIdSdk = blinkIdSdk,
    cameraSettings = CameraSettings(
        lensFacing = CameraLensFacing.LensFacingFront,
    ),
    onScanningSuccess = { result ->
        // use result
    },
    onScanningCanceled = { }
)

iOS (Swift)

Pass ScanningUXSettings with preferredCameraPosition set to .front via the .uxSettings() modifier:

BlinkIDUXView(
    analyzer: analyzer,
    onScanCompleted: { resultState in
        guard let result = resultState.scanningResult else { return }
        // use result
    }
)
.uxSettings(ScanningUXSettings(preferredCameraPosition: .front))
