I know how it used to work -- I've been following Square from the beginning. I just don't think it would cost that much to outsource verifying a DL and bank statement that I upload to their website.
Its certainly better than their response.
If they verify the identity and know they are going to make it back in fees or however square does business, then sure.
It doesn't matter very much that someone could use a stolen credit card for that $25 payment, because square would deny such a person during their deeper investigation and lose less than $25 dollars total. And there is little reason for the criminal to do this because it will get one of their nice card numbers blocked faster.
Or ignore the second paragraph and charge cash for the service of doing a better investigation with responsive customer support.
