OCR (Optical Character Recognition)
Of course Receipts can also recognize and process text from scans. A searchable PDF is automatically created from the image file, which is then recorded in the database.
For optimal results it is recommended to scan at least at 300 DPI. The higher the resolution, the better for text recognition.
Particularly good results can be achieved with a document scanner such as ScanSnap. The use of the OCR software Abbyy FineReader is preferable.
