MRZ
Scan capability overview
The Anyline MRZ mode provides the functionality to scan passports and other IDs holding a Machine Readable Zone (MRZ).
For each scan result, the MRZ mode generates an Identification object, containing all relevant information of the scanned document.

Other Machine Readable Documents
MRZ on Swiss Driving License
The MRZ on Swiss driving licenses is not following the ICAO standards. It consists of three lines - one line of 9 and two lines of 30 characters each.
For a full specification, we refer to the ASTRA brief
MRZ Check Digits
Travel documents following the ICAO standard contain multiple check digits.
When enabling the strictMode in the plugin config, a result is only returned if all check digits on the scanned document are valid. This can improve the quality of the returned result, but might also increase the scan duration. In this case the scanned document must follow the ICAO standard, otherwise the document will not scan.
Scannable Visual Inspection Zone Information
The Anyline MRZ mode also provides the functionality to scan the Visual Inspection Zone (VIZ) of passports and other IDs in parallel to the MRZ. The fields of the visual inspection zone are prefixed with viz in the result.
VIZ Supported document types and countries
Below are tables that show which VIZ fields are supported for which countries and document types. VIZ fields might be NULL for supported countries and document types in the following cases:
-
The field is not visible in the cutout.
-
The quality of the scanned field is not good enough (it does not pass the validation check).
For non supported document types and countries, the fields will always be NULL.
