What is an MRZ?

MRZ stands for Machine-Readable Zone. It is an area designed to be automatically read by an optical reader (e.g. a scanner) located at the bottom of identity document (ID cards, passports, residence permits, etc.). It comprises between one and three lines of alphanumeric characters and chevrons (<). Apart from the data already mentioned in the upper part of the document, this zone, with a very precise layout, contains codes enabling a compliance check to be carried out.

What checks are carried out by

The identity document analysis service is based on a variety of checks. These controls are different depending on the document submitted; they include the verification of compliance of the MRZ or the bar code, compliance between the information in the MRZ or in the bar code and that printed on the document, the overall appearance of the document, the security patterns on the documents and whether the document has expired.

No document is detected?

The document submitted has not been recognized. Maybe the submitted image cannot be automatically analyzed. For optimal analysis of the submitted documents, we recommend a resolution that permits easy reading of the information printed on the document. No credit will be deducted until a detailed inspection report is returned to you.
