    Article summary

    The OneSpan Image Generator SDK generates standard black and white QR codes and Cronto images from a string value.

    The Image Scanner SDK provides a native component for a mobile application to integrate QR code and Cronto image capture.

    QR code image

    The QR Code image contains up to 4296 characters.

    Cronto image

    The Cronto image contains up to 1070 hexadecimal characters.

    If the Cronto image is supposed to be scanned with a OneSpan device (e.g. Digipass 760, Digipass 780), the data must be limited to 200 hexadecimal characters. Specific APIs must be called to generate compatible Cronto images.

    For more detailed information about each SDK and integration instructions, see the Image Generator SDK Integration Guide and the Image Scanner SDK Integration Guide.
