Thanks for your explanation. I do believe they are not outside of their bounds in wanting to verify my identity. You are correct that my concern is the security of my ID document. I'm curious how email encryption would solve this problem. Presumably it would make for the secure transmission of the document, but I would still be left with DOs word that the document would be completely deleted after they viewed it and not kept on file. I just hate the thought of my CC info and government ID sitting somewhere on their servers and then hearing they had a security breach (for the very reasons that you specified - CC alone == promise, CC + ID == identity theft?).
