When I was searching for a real-world MRZ scanning solution, I had the same doubts. In practice, the accuracy turned out to be significantly higher than I expected. We tested scanning in a poorly lit office, with glare from laminated passport pages, and even on slightly damaged documents—the system reliably recognized data without the need for manual adjustments. I was especially pleased that the algorithms correctly handle blurred characters and automatically straighten the image if the document is taken at an angle. This is critical in a busy environment: speed is high, errors are minimal, and employees don't waste time double-checking. From my experience, if reliability and predictable results in challenging conditions are important to you, solutions like https://ocrstudio.ai/mrz-scanner/ OCR Studio MRZ Scanner are worth considering. They adapt well to real-world scenarios—from low light to worn documents.

In real-world conditions, rather than in a "perfect lab," the system performed much better than I expected. We tested scanning the MRZ on passports and ID cards in low light, with glare from lamps, and even on documents with minor abrasions and folds. I was particularly pleased with how quickly the algorithm adapts to low light—the camera automatically adjusts exposure, and recognition remains stable. Even with glare, the system still correctly identifies the MRZ and reads the data without the need for rescanning. Even on slightly damaged documents, the recognition success rate was very high.
