Abstract

An electronic transaction system for conducting electronic financial transactions including a smart card configured to store a plurality of payer electronic credits and a communication module configured to transmit the electronic credits from the smart card to a party selected from a plurality of addressable parties accessible through a Public Switched Telephone Network. The smart card having a storage device configured to store the electronic credits and a computational device configured to debit or credit the electronic credits. The communications module including an actuation device configured to generate a signal for transmitting the electronic credits to the party, a routing device configured to produce an address of the party, a video display unit configured to display credit transfer data, and a keypad configured to enter details of an electronic transfer. Wherein, the payer remains in physical control of the smart cart at all times during conduct of the transaction.

Claims

1. An electronic transaction system for conducting electronic financial transactions, comprising:

a smart card configured to store a plurality of payer electronic credits, comprising,

a storage device configured to store said electronic credits, and,

a computational device configured to debit or credit said electronic credits; and

,

a communications module comprising a mobile phone configured to transmit, in response to a transaction between the payer and a party selected from a plurality of addressable parties accessible through a Public Switched Telephone Network (PSTN), said electronic credits from said smart card to said selected party via said PSTN, comprising,

an actuation device configured to generate a signal for transmitting said electronic credits to said party,

a routing device configured to produce an address of said party,

a video display unit configured to display credit transfer data, and

a keypad configured to enter details for an electronic transfer;

wherein said payer remains in physical control of the smart card at all times during conduct of said transaction and said smart card is configured to act as a subscriber information module (SIM) for said mobile phone.

2. The electronic transaction system of claim 1, wherein said smart card is further configured to store addresses of said plurality of addressable parties.

3. The electronic transaction system of claim 1, wherein said smart card is further configured to be accessible by use of a personal identification number.

4. The electronic transaction system of claim 1, wherein said communication module is configured to receive a signal representing an electronic receipt for a payment made by said communication module and transfer details of said electronic receipt to said smart card, and said smart card further comprises a second storage device for storing said electronic receipts.

5. The electronic transaction system of claim 1, wherein said smart card further comprises an encryption algorithm and said communication module is configured to transmit encrypted signals.

6. The electronic transaction system of claim 5, wherein said encryption algorithm comprises a Rivest, Shamir and Adleman algorithm.

7. Th electronic transaction system of claim 5, wherein said smart card further comprises a signature device configured to generate a secure electronic signature.

8. The electronic transaction system of claim 1, wherein at least one party of said plurality of addressable parties has an electronic till configured to receive said transmitted electronic credits.

9. The electronic transaction system of claim 8, wherein said electronic till is configured to issue electronic receipts.

10. The electronic transaction system of claim 9, wherein at least one party of said plurality of addressable parties comprises an electronic banking terminal configured to process signals relating to electronic money transfers from one bank account to a second bank account.

11. The electronic transaction system of claim 8, wherein said communication module is further configured to transmit through a mobile network.

12. The electronic transaction system of claim 8, wherein at least one party of said plurality of addressable parties has an electronic till associated with a parking meter.

13. The electronic transacting system of claim 8, wherein at least one party of said plurality of addressable parties has an electronic till associated with a restaurant.

14. The electronic transaction system of claim 8, wherein at least one party of said plurality of addressable parties has an electronic till associated with a gaming outlet.

15. A method for transferring electronic credits using a telecommunication system, comprising the steps:

entering into a communication module comprising a mobile phone an amount of electronic credits to be transferred to a party and an address of the party selected from a plurality of addressable parties accessible through a Public Switched Telephone Network to which said amount is to be transferred;

debiting said amount of said electronic credits from an amount of payer electronic credits stored on a smart card reflecting a balance prior to said entering step;

using the smart card as a subscriber information module (SIM) for said mobile phone;

transmitting an encrypted signal including said amount and an electronic signature to the address of said party; and

transmitting a response signal from the party to said communicating module, said response signal comprising an acknowledgment of receipt and an electronic signature.

16. The method of claim 15, wherein said transmitting an encrypted signal step further comprises:

using a Rivest, Shamir and Adleman (RSA) algorithm.

17. The method of claim 15, wherein said entering step further comprises:

entering an address of a bank at which the payer has an account and an account number.

18. The method of claim 17, wherein said step of transmitting an encrypted signal further comprises:

transmitting a signal indicating the amount to be transferred, the address of the party, the account number and an electronic signature of the payer.

19. The method of claim 18 wherein said step of transmitting a response signal further comprises:

transmitting a signal to the electronic till of the party confirming payment.

20. The method of claim 19, wherein said step of transmitting an encrypted signal further comprises:

encrypting said transmissions using a RSA algorithm.
