OCR font decoding is possible in some readers. OCR is not a robust decoder because it interprets pixel images to represent letters and numbers. If the printing is bad, or the image captured is too small, it may interpret letters incorrectly, like a 'W' may look like a 'U' or a 'V'. To add to the robustness, you may utilize an extra check digit.

Only Imager product models (and not laser nor linear CCD models) will possibly have OCR capability, and not all imager based products have this capability. Use the newer model readers for better results, such as the OPI3201.

Only OCR-A & OCR-B is possible. Evaluate & Test the reader first before purchasing to see if it meets your needs.

The MDI3x00 and MDI4x00 based modules and scanner families only decode OCR-B and they only decode specific documents with known character counts. Their command set is different than the linked OCR document below. See the MDI3x00 or MDI4x00 Serial Interface Manual for these commands.
