Abstract

A method and system for conducting payments with a wireless terminal by a user in exchange for goods and services rendered by a merchant. In an embodiment of the invention, a Wireless Application Protocol (WAP) server for use with a WAP compliant terminal enables the user to browse merchants from a portal page over an HTTP connection. The user selects items for purchase in which payment to the merchant is initiated using the Secure Electronic Transaction (SET) protocol to a Server Wallet server. In one aspect of the invention, the user provides proof of identity and confirmation for the payment with a digital signature calculated by a Wireless Identity Module (WIM) operating with the wireless terminal. The Server Wallet, which retains sensitive financial information such as a payment card accounts e.g. credit cards numbers, carries out the payment transaction to the merchant on behalf of the user. The result of the transaction is returned to the user via standard secure WAP protocols.

Claims

1. A method of shopping for items selected online by a mobile user from a merchant via a wireless telecommunication system, said method comprising the steps of:

establishing a wireless connection with a gateway server by said mobile user;

browsing said merchants for items of said goods and services;

selecting said items the user intends for purchase from said associated merchant;

initiating a transaction for payment by said merchant for said selected items to a trusted financial entity capable of making payment on behalf of said mobile user, wherein said payment transaction occurs without the transmission of sensitive user financial data outside the financial entity; and

relaying the results of the transaction to the mobile user via the wireless connection.

2. A method according to claim 1 wherein said gateway server is a WAP Server operating in accordance with Wireless Application Protocol (WAP), and wherein said WAP Server is in wireless communication with said mobile user using standard WAP procedures.

3. A method according to claim 2 wherein said browsing occurs through a WAP portal page arranged to present said plurality of available merchants and provide selectable links to said merchants and their goods and services.

4. A method according to claim 1 wherein said trusted financial entity is a Server Wallet server performing a service capable of conducting online payments on behalf of the mobile user.

5. A method according to claim 4 wherein the Server Wallet contains payment card numbers associated with the mobile user.

6. A method according to claim 1 wherein the payment transaction between the merchant and the financial entity occurs in accordance with the Secure Electronic Transaction (SET) protocol standard.

7. A method according to claim 4 wherein the initiating a transaction for payment step includes sending a wakeup message intended for the user by the merchant, and wherein the message is instead received by the gateway server and forwarded to the Server Wallet.

8. A method according to claim 2 wherein a Wireless Identity Module (WIM) is used together with the wireless terminal to calculate a digital signature for confirming the transaction payment.

9. A method according to claim 1 wherein said goods and services purchased may include digital content such as music, movies, electronic books, games, video clips, or other kind of entertainment content which may be used in the user'"'"'s terminal or transferred to an appropriate terminal for use.

10. A system for making payments by a user with a wireless terminal for items selected from a merchant, said system comprising:

a gateway server in wireless communication with said wireless terminal for providing the user access to said merchant via an HTTP connection;

an entity having stored financial information of the mobile user is securely connected to said gateway server and connected to said merchant via a secure transmission protocol; and

means for authenticating the user to the entity to provide payment to the merchant from the financial information.

11. A system according to claim 10 wherein the gateway server is a Wireless Application Protocol (WAP) Server.

12. A system according to claim 11 wherein the entity is a Server Wallet.

13. A system according to claim 12 wherein the secure transmission protocol between the merchant and the Server Wallet is Secure Electronic Transaction (SET) protocol.

14. A system according to claim 13 wherein a SET payment gateway operating on behalf of the merchant is connected to the Server Wallet.

15. A system according to claim 11 wherein said means for authenticating the user includes a digital signature calculated by an Wireless Identity Module (WIM) hosted in the wireless terminal.

16. A system according to claim 14 wherein the WAP Server further comprises a component for intercepting a wakeup message sent from the merchant and for forwarding the wakeup message to the Server Wallet.

17. A system according to claim 11 wherein a WAP portal is used to provide a link to the merchant via an HTTP connection.

19. A method according to claim 18 wherein the gateway server is a WAP server operating in accordance with Wireless Application Protocol (WAP).

20. A method according to claim 18 wherein the authentication details used to authenticate the user to the Server Wallet entity includes the use of a digital signature.

21. A method according to claim 20 wherein a Wireless Identity Module (WIM) operating together with the wireless terminal is used to compute a digital signature for authenticating the user to the Server Wallet.

22. A method according to claim 20 wherein the authentication details further include the use of passwords, fingerprints, and retinal scans.

23. A method according to claim 19 wherein the query message is a wakeup message received by the WAP server from the merchant and forwarded to the Server Wallet entity, and wherein the transaction involving the executed payment is sent to the merchant in accordance with the Secure Electronic Transaction (SET) protocol.

18. A method of conducting payment for goods and services from a merchant with a wireless terminal using a payment system, wherein the system is characterized in that a gateway server is in communication with the wireless terminal and the merchant such that a query message from the merchant for payment is received by the gateway and sent to a Server Wallet entity that effects payment to the merchant, the method comprising the steps of:

establishing a secure connection between the wireless terminal and the gateway server;

sending the query message from the merchant which is received by the gateway;

forwarding the query message from the gateway to the Server Wallet entity;

authenticating a user of the wireless terminal to the Server Wallet entity by using authentication details originating from the user;

executing payment from the Server Wallet entity to the merchant; and

confirming the payment to the user.
