Abstract

A method and system is disclosed herein for conducting money or value point transactions between a first mobile device and a second mobile device in a network of a plurality of mobile devices. Each mobile device contains a radio frequency identification module with a digital wallet on each said mobile device for storing and processing digital value points. Digital certificates are provided in each mobile phone for the purpose of authenticating the mobile devices. The transaction is initiated by the first mobile device with the second mobile device by exchanging RFID identifiers and digital certificates via radio frequency identification transmission and reception. Digital certificates can be exchanged between the digital wallets of the first and second mobile devices using radio frequency transmission. The method and system disclosed herein allows users equipped with RFID enabled mobile devices to transact over a short range without a need for connectivity to a banking infrastructure or a central network.

Claims

1. A method of conducting a transaction between a first mobile device and a second mobile device in a network of a plurality of mobile devices, wherein each mobile device contains a radio frequency identification module with an identifier, comprising the steps of:

providing digital wallets on each said mobile device for storing and processing digital value points;

providing digital certificates in the first mobile device and the second mobile device;

initiating a transaction by said first mobile device with said second mobile device;

exchanging radio frequency identification identifiers between the first mobile device and the second mobile device via radio frequency identification transmission and reception;

authenticating the unique identity of the second mobile device by the first mobile device using said received radio frequency identification identifier from the second mobile device;

transacting value points between the digital wallet of the first mobile device and the digital wallet of the second mobile device, wherein said transaction is carried out using radio frequency identification transmission; and

updating the balance of digital value points in the digital wallet of the first mobile device and the digital wallet of the second mobile device.

2. The method of claim 1 wherein transacting value points comprises one or more of the following:

transacting cash, transacting credit and transacting debit.

3. The method of claim 1, wherein the step of transacting value points further comprises the step of transacting value points for digital content which is transferred between the the first mobile device and the second mobile device through radio frequency communication, wherein the user of the first mobile device buys digital content from the user of the second mobile device.

4. The method of claim 1 wherein the mobile devices include mobile phones, hand held computing devices, computers, personal digital assistants and automated teller machines.

5. The method of claim 1 wherein said digital wallets store digital value points against its respective currency mode, and wherein transactions between two different currency modes further comprise the steps of determining the currency mode associated with said points accrued in the memory of the first mobile device by comparing the currency mode indicator associated with said points with a currency mode identifier contained in the transaction details stored in the memory of first mobile device, and determining a match between said identifier and said indicator.

6. The method of claim 2 wherein the method of conducting a credit transaction further comprises the steps of:

establishing a credit account associated with the primary account of the first mobile device;

receiving a request from the first mobile device to transmit a certain amount of digital points specified by the user of the first mobile device,

transferring said specified amount of digital points to the second mobile device by the first mobile device; and

,

calculating and storing the amount of credit outstanding in the both the first mobile device and the second mobile device.

7. The method of claim 2 wherein the method of exchanging digital points that can be disbursed for goods and services within an organization between a first mobile device and a second mobile device in a network of plurality of mobile devices in an organization further comprises the steps of:

issuing digital points to the users of mobile devices within said organization, wherein said step of issuing digital points is performed by a controller module of said organization that is located on a server on the internet;

receiving a request from the first mobile device by the second mobile device to transmit an amount of digital points specified by the user of the first mobile device; and

,

transferring digital points from the first mobile device to the second mobile device via radio frequency.

8. The method of claim 1, wherein the first mobile device and second mobile device transact with automated teller machines with in-built radio frequency identifier modules.

9. The method of claim 8 wherein the method of transacting cash between a first mobile device and an RFID enabled automated teller machine further comprises the steps of:

transmitting a digital certificate from the first mobile device to said automated teller machine for the purpose of identifying the first mobile device;

comparing a stored digital certificate in the automated teller machine to the digital certificate received from the first mobile device;

replying via radio frequency to the first mobile device of the successful execution of authentication process, if the stored digital certificate and the transmitted digital certificate from the first mobile device successfully match;

receiving a request from the first mobile device by the automated teller machine to transmit an amount of money specified by the user of the first mobile device; and

,

transferring the amount requested in the form of digital value points by the automated teller machine to the first mobile device.

10. The method of claim 3 wherein the first mobile device can transact with a radio frequency enabled computer to perform on-line internet transactions.

11. The method of claim 1 wherein the step of updating the balance of digital value points in the first and second mobile devices further comprises the steps of:

determining the time and date of completion of the transaction by the first mobile device and the second mobile device;

associating said time and date of completion of transaction by the first mobile device with the monetary increment or decrement in the electronic wallet of the first mobile device and the second mobile device, and storing said associated information of time and date of completion of transaction and transaction information in the memories of the first mobile device and the second mobile device;

calculating the balance of digital value points in the first mobile device and the second mobile device after completion of the transaction between the first mobile device and the second mobile device;

storing the value of balance of digital value points in the memory of the first mobile device and the memory of the second mobile device; and

,

updating the primary reserve accounts of the first mobile device and the second mobile device.

12. A system of conducting a transaction between a first mobile device and a second mobile device in a network of a plurality of mobile devices, comprising:
