We are evaluating using OCR to process our remittance devices. One requirements is that we provide a check digit on the finder number. Is anyone out there utilizing this in their marketing efforts? I am looking for any pitfalls or things to look out for. If I understand correctly, once you turn on the setting on the Finder # to provide a check digit for all efforts going forward. How does this impact data entry in a Enhanced Revenue Batch, does the check digit need to be included with the Finder#? Any feedback/input is appreciated.
