You unencrypt it using your private key (the public half of which was used 
to encrypt the card in the first place). Obviously you want to protect this 
adequately, so use a passphrase and any other means available to you, such 
as emailing the order to a different user than the one who owns the 
catalog. Ideally, the order email with encrypted card info would go to a 
different box, and so the private and public keys would not need to be 
stored on the same machine.
