In business automation
OCR is the reading step, not necessarily the understanding step. After extracting the text, fields need to be identified, amounts checked, and a decision made about how to handle a blurry image or an unrecognized number.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Business process example
A scanned invoice arrives by email. The text is extracted, the document number and date are identified, and the amount is compared with the calculated fields. A document that does not pass validation remains pending approval before it is entered into the business system.
Relevant tools

What to check
- Do not save every sequence of digits found as an invoice number. Keep a link to the original image so errors can be checked.
