Or you could use a password and generate a keyfile from text stored on the ring. Ideally, the ring would have to be at least Ultralight C or Mifare plus as they have encryption. (Perhaps a future upgrade) Another method may be to access an encryption key online via a password and that is used to decrypt sector stored information on the ring. A simple and immediate boost to security might be to use information contained on your ring now as password padding.

yeah it seems to be an problem with that USB port.
