        We present new micropayment schemes that are more efficient
        and user friendly than previous ones.   These schemes reduce
        bank processing costs by several orders of magnitude, while 
        preserving a simple interface for both users and merchants.
        The schemes utilize a probabilistic deposit protocol that,
        in some of the schemes, may be entirely hidden from the users.                  
                 },
