Refer the attached BO which you need to Import and call it from a Process although you can test it and see that its working from the BO itself.
The only difference is in the Application Modeller using the Region mode you need to correctly spy the text area around the actual <Pan Number> on your image. The sample image I have chosen is a different one so the area (or the Region) where the pan number is on your image would be different.
Also since you have 10 images you will need to make modifications to it like - add it to a collection (say colScannedPAN). Once all 10 are finished then read the Excel List into another Collection (say colExcelPAN) using 'Get Worksheet as Collection', then you can loop through any one of these collections (you need to know which one) and use 'Collection Contains Value' action to check against another collection.
