STUPID!
How the heck do you prove the transferee is an illegal? Or are we going to ASSUME the transfer is illegal until you produce your Birth Certificate, Passport, etc.?
You produce your drivers license, VISA, passport, etc... just like you have to have ID to cash a check at a bank.
Look in your wallet. My guess is that you have a drivers license. Not that tough. You probably have even used it to cash a check.

That's easy. Just say, "Ausweiss bitte!" to anyone with dark skin who tries to transfer money. You can ignore all the others, you see, since only dark-skinned people could be illegals.
And it's all legal, because it's not the cops demanding your papers, you see. You get the bank teller to do it, and it's not a police state.
