Supported documents

See what Scanverion can read.

Clearly invalid AI specimens are based on linked public document layouts. The cards distinguish an API category from the structured Scanner output that has been implemented and tested.

AI-generated demo images use fictional data, visible SPECIMEN markings and invalid machine-readable values. They are not real or customer documents.

Generic documents

Visual operations work beyond known document types.

Checkboxes, barcodes, signatures, faces, blur and rotation can be analysed on forms, contracts, scans and unknown documents. A dedicated Scanner profile is not required.

  • Detection: Locate documents and other objects.
  • Rotation: Measure document orientation.
  • Blur: Evaluate image sharpness.
  • BarcodeReading: Read QR and linear barcodes.
  • CheckboxDetection: Evaluate checkbox regions supplied in the request.
  • SignatureDetection: Detect a visible signature.
  • FaceDetection: Locate visible faces.
  • FaceExtraction: Return detected face regions.
Example fields

CheckboxDetection uses CheckboxDefinitions supplied with the request. Full-image scanning can also return requested ScannerFields.

Country support

Coverage follows the document standard and issuing layout.

Passport MRZ data is standardized globally. Identity cards and other national documents require a tested layout for that country and document generation.

01

Passports

MRZ fields from any passport with a readable ICAO TD3 MRZ
Additional printed layouts tested
SKFICHUA

The MRZ provides names, document number, dates, sex and nationality. Additional printed fields depend on the national layout.

02

National identity cards

Structured fields for supported front and back layouts
Country layouts tested
SKCZHURODEATPL

Front and back coverage varies by country and card generation.

Common questions

Which documents and countries are supported?

Passports: MRZ fields from any passport with a readable ICAO TD3 MRZ The MRZ provides names, document number, dates, sex and nationality. Additional printed fields depend on the national layout.

National identity cards: Structured fields for supported front and back layouts Front and back coverage varies by country and card generation.

Invoice: Layout-based invoice extraction

Any document or form: Generic fields and document-independent visual operations

How do I choose which fields to extract?

Use Scanner for supported document layouts. For full-image scanning, request ScannerFields explicitly; they are required when Scanner is combined with DisableObjectSegmentation. Visual operations do not require a dedicated document profile.

Which input files can I send?

The document-processing endpoint accepts JPEG, PNG, WebP and PDF files up to 10 MB. Supported fields depend on the document layout and requested operations.
