I have sent CASH and DEBIT cards to Thailand and to Phil. On each occasion, I used an old 'junk mail' envelope, which had printing, which made it appear that it was junk mails, maybe advertising houses. I then made sure the packing around the card was thick enough so that a person feeling the envelope would not be able to feel there was a card. Once I cut out a card sized hole in a piece of cardboard which as the same thickness as the ATM card. I then sellotape the card into the hole and posted in ordinary mail.
And lastly, I made sure there were no funds in that account.
I of course called the person in Thailand / Phil to tell them the PIN.
So far !!!!!!! No problems
