How to send money across borders physically and inexpensively, but not via cash?
I assume the same criteria apply for this as your previous question. You want to physically transfer in excess of 50,000 USD multiple times a week and you want the transportation mechanism to be instant or very quick. I don't believe there is any option that won't raise serious red flags with the government entities you cross the boundaries of. Even a cheque, which a person in the comments of OP's question suggests, wouldn't be sufficient due to government regulation requiring banks to put holds on such large amounts.
