FALLBACK
A fallback was triggered on the current JumioScanMode. It can be either initiated by the user JumioFallbackReason.USER_ACTION or automatically due to low performance JumioFallbackReason.LOW_PERFORMANCE or no detection during a given time frame JumioFallbackReason.NO_DETECTION. The JumioFallbackReason is delivered in the data parameter of JumioScanPartInterface.onUpdate.
