The Machine ReadableZone (MRZ) is a codified element of identity documents that contains the document holder's basic personal details, including full name, document number, date of birth, sex and document expiration date.
This information extracted can be used to validate the data extracted from the body of the passport (excluding the MRZ). In the case where the information extracted from the body of the passport matches the detail in the MRZ, our confidence in that data point will be increased to 100%, so will be auto-validated if you choose to set this feature on. Using the MRZ enhances the accuracy and confidence in the information extracted and saves time in validating the model predictions.
