Do you have to use the card itself? Here, if you don't have your card, you can use your phone number. Have the card sent to a "fake" address and just remember the phone number you provided. (Pick an address where someone moved about 8 months or so ago or pick a big apartment building and it will probably get trashed by the receipient instead of being sent back.) What happens if you lose the card? Do replacement cards get mailed, too?
