    4 Sahana OCR Module is responsible to generate OCR-able PDF Form for every resource Form available in HTML. There are two types of interfaces available based on the usecase.
    5 1. Single Form Upload
    6   When there is human resource available to upload and verify the OCR-ed data individually then this interface can be considered. Here the user will upload a scanned Form, let eden OCR it, then he/she can verifies the data and update the database with this new record.

    8 2. Bulk Form Upload
    9   When there is not enough human resource available to upload and verify the OCR-ed data then this usecase can be considered where scanned forms can be uploaded in bulk and verified later.
     6Optical Character Recognition (or just OCR) in Sahana Eden is used to facilitate electronic data collection by providing paper
     7based data collection as an alternative by which one can download and print a blank FORM and upload them back after data entry.
     8The OCR software in Sahana Eden will then read them and store the data electronically.
