About this tool
The MRZ Scanner uses on-device OCR with an MRZ-tuned Tesseract model to read the Machine Readable Zone from a photo or scan of a passport, ID card, residence permit or visa. Images are auto-rotated, contrast-normalized and cropped to the MRZ area before recognition. The extracted MRZ is then parsed and validated against ICAO Doc 9303 — including every field-level and composite check digit.
For best results, use a sharp, straight-on image with good lighting where the two or three MRZ lines at the bottom of the document are fully visible and not cropped.
