Class ReadOnlyCameraManager

Object

com.scantrust.mobile.android_sdk.camera.ReadOnlyCameraManager

public class ReadOnlyCameraManager
extends Object

The ReadOnlyCameraManager does the same camera and surface view setup as ScanTrustCameraManager but does not perform the image and frame processing required for the ScanTrust authentication. It is limited to checking the ownership of the code based on its content. When only the QR code format is chosen, it is capable of dealing with multiple (QR) codes in the same frame.
