Issue
A document with MRZ can't be recognized or MRZ recognized not properly.
Solution
If you are using Document Reader SDK version 6.2 and above, to improve MRZ recognition you can process image with parameter:
{"mrzDetectMode" : 1}You can test it here, by putting a string as shown on the screenshot below to Custom parameters field.
If the image is of extremely poor quality or has an excessively motley background, you can try using parameter:
{"mrzDetectMode" : 2}
