Embed an encrypted passive rfid chip in "Joe" or his dog that contains the passphrase. Then take a hundred unencrypted rfid chips with the password to the encrypted embedded rfid chips, and scatter them in a field somewhere. If Joe forgets the passphrase all he has to do is go to the location where he scattered the other chips. Apparently rfid has a 3 foot range so it shouldn't be hard to find one of the hundreds of rfid tags he scattered previously. Once found he will have the password to his embedded chip, so he can then unencrypt the passphrase held in the embedded chip in his body, and recover it. Something tells me I just made that way more convoluted than necessary

edit: okay, new, even worse idea.. embed 4 rfid tags... one in each hand and one in each foot. Only the rfid tag in your right foot is unencrypted. It contains the password to unencrypt the rfid tag in your left foot... which contains the password to unencrypt the rfid tag in your left hand.. which contains the password to unencrypt the rfid tag in your right hand which.. you got it.. contains the passphrase to your wallet. So you go clockwise with the rfid detector.. right foot (unencrypted), left foot, left hand, right hand and passphrase.
