I agree that it might well reduce costs and fraud - but how will it improve privacy? Your name is already on the card ... and the issuer will still have a list of your transactions. Not having to show ID may save annoyance, but it doesn't significantly improve privacy. -- Peter Fairbrother --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
