Apparatus and method for secure transacting
First Claim
1. A method for withdrawing electronic representations of money, comprising the steps of:
- establishing a first session between a transaction module and a first teller module;
establishing a second session between said first teller module and a second teller module;
transferring an electronic representation of money from said second teller module to said first teller module via said second session;
transferring said electronic representation of money from said first teller module to said transaction module via said first session;
after said transaction module receives said electronic representation of money, said first teller module and said transaction module committing to their transaction; and
after said first teller module and said transaction module commit to their transaction, said second teller module and said first teller module committing to their transaction.

Abstract
An improved monetary system using electronic media to exchange economic value securely and reliably. The invention provides a complete monetary system having electronic money that is interchangeable with conventional paper money comprising (1) issuing banks or financial institutions that are coupled to a money generator device for generating and issuing to subscribing customers electronic money including electronic currency backed by demand deposits, or electronic credit authorizations; (2) correspondent banks that accept and distribute the electronic money; (3) a plurality of transaction devices that are used by subscribers for storing electronic money, for performing money transactions with the on-line systems of the participating banks or for exchanging electronic money with other like transaction devices; (4) teller devices, associated with the issuing and correspondent banks, for process handling and interfacing the transaction devices to the issuing and correspondent banks, and for interfacing between the issuing and correspondent banks themselves; (5) a security arrangement for maintaining the integrity of the system; and (6) reconciliation and clearing processes to monitor and balance the monetary system.

5. A method for withdrawing electronic representations of money, comprising the steps of:
-
establishing a connection between a transaction module and a teller module, wherein said transaction module stores a plurality of electronic representations of money each associated with a monetary amount; said transaction module transferring its stored electronic representations of money to said teller module; a money generator module generating a new electronic representation of money having a total monetary value equal to a withdrawal amount plus a total value of all said electronic representations of money transferred from said transaction module; and said teller module transferring said new electronic representation of money to said transaction module. - View Dependent Claims (6, 7, 8)

19. An electronic transaction device comprising:
-
an external interface; an electronic processor in communication with said interface; cryptography means; a memory that stores electronic representations of money and security parameters; power means; and wherein said transaction device is adapted so that after said transaction device has lost and then regained power, it will not be able to transfer said electronic representations of money until said transaction device connects to a security server and has its security parameters updated.

20. An electronic transaction device comprising:
-
an external interface; an electronic processor in communication with said interface; cryptography means; a memory that stores electronic representations of money, module personalization data including owner identification characteristics, and bank account profiles; wherein said transaction device is adapted to compare said owner identification characteristics to data input in an attempt to access said transaction device; and wherein said transaction device is further adapted so that initial personalization of said transaction device is inhibited if said transaction device detects either a bank account profile or electronic representations of money already stored in said memory.

21. An electronic monetary system comprising:
-
a money generator module that generates electronic representations of money each one including a monetary value and an expiration indicator providing a period of validity for said electronic representation of money; a transaction module that stores and transfers said electronic representations of money to other transaction modules; wherein said money generator module is adapted to provide a shorter period of validity for electronic representations of money having a high monetary value than for electronic representations of money having a lower monetary value.
