It seems Paxum will not accept identification if you place a watermark on the scan which says "For Paxum ID Purposes Only".
There's no way in hell I'm going to give any company a large format scan of my Passport or other Identification documents for potential misuse later on.
If all Paxum need the documents for is for Know Your Customer then a watermark stating "For Paxum ID Purposes Only" should not matter. On the other hand, a large format clear unwatermarked image of an ID document would be perfect for ID fraud down the track
Paxum: Don't expect your customers not to take precautions with valuable documents.
