Extraction of data from Machine Readable Zones (MRZ)
ABBYY FineReader Engine can detect a machine-readable zone on the image of an ID or travel document and extract data that is encoded in accordance with the ICAO Document 9303.
FineReader Engine will extract machine-readable data from both types of MRZ fields:
- 2 lines
- 3 lines
Additional information that can be extracted:
- Number of lines in MRZ
- All characters from each line
- Optional data from each line
- Type and subtype of ID document
- Number of ID document
- Code of issuing state
- Date of expiry
- Surname & All given names
- Nationality
- Date of birth & sex
- Personal number
Where available, the Engine extracts check digits of each value. To provide information about the quality of data extraction, it uses Boolean value that specifies whether the checksum over the individual value matches the check digit.
Note: This feature is only available in ABBYY FineReader Engine for Windows. It is not currently supported in ABBYY FineReader Engine for Linux or ABBYY FineReader Engine for Mac.
Optical mark recognition
ABBYY FineReader Engine recognizes simple checkmarks, grouped checkmarks, model checkmarks and checkmarks that were corrected by hand:
- Checkmarks in a square frame
- Checkmarks against the empty background
- Non-standard checkmarks (this type of checkmarks requires prior training)
