Abstract

The present invention relates to a secured transaction system. In one embodiment, a mobile transaction processing agent system includes a communication module configured to receive a secured transaction description from a mobile client device or an encrypted transaction description from a point-of-sale (POS) device, wherein the secured transaction description is in the form of a bar code generated by the mobile client device, an authentication module configured to decode the secured transaction description and verify the secured transaction description is valid based on the mobile client device or the point-of-sale device, and a transaction processing module configured to process the transaction in accordance with the secured transaction description.

Claims

1. A mobile transaction processing agent system, comprising:

a communication module configured to receive a secured transaction description from a mobile client device or an encrypted transaction description from a point-of-sale (POS) device, wherein the secured transaction description is in the form of a bar code generated by the mobile client device;

an authentication module configured to decode the secured transaction description and verify the secured transaction description is valid based on the mobile client device or the point-of-sale device; and

a transaction processing module configured to process the transaction in accordance with the secured transaction description.

3. The mobile transaction processing agent system of claim 1, wherein the one or more POS devices comprise:

an input module configured to receive the secured transaction description from a mobile client device;

an encryption engine configured to generate an encrypted transaction description using the secured transaction description from the mobile client device; and

a communication module configured to transmit the encrypted transaction description for processing.

4. The mobile transaction processing agent system of claim 1, wherein the secured transaction description describes a mobile cash transaction, a mobile check transaction, or a mobile credit card transaction.

5. The mobile transaction processing agent system of claim 1, wherein the bar code includes a one dimensional bar code or a two dimensional bar code.

6. The mobile transaction processing agent system of claim 1, wherein the communication module is configured to communicate with one or more issuer servers for processing the secured transaction description generated by the mobile client device.

7. The mobile transaction processing agent system of claim 6, wherein the communication module is configured to send a transaction record to the mobile client device upon finish processing the secured transaction description.

8. The mobile transaction processing agent system of claim 1, wherein the communication module is configured to communicate with one or more acquirer servers for processing the encrypted transaction description generated by the POS device.

9. The mobile transaction processing agent system of claim 8, wherein the communication module is configured to send an acknowledgement transaction packet to the POS device upon finish processing the encrypted transaction description.

10. The mobile transaction processing agent system of claim 1, wherein the transaction processing module comprises:

logic for generating a transaction record in accordance with the secured transaction description, wherein transactions in the transaction record include corresponding point-of-sale GPS locations of the mobile client device near the time of the transactions.

11. The mobile transaction processing agent system of claim 10, wherein the transaction processing module further comprises:

logic for verifying validity of the transactions using the corresponding point-of-sale GPS locations of the mobile device;

logic for identifying fraudulent activities according to discrepancy between transaction location and actual GPS location of the mobile client device; and

logic for reporting fraudulent activities to a user of the mobile client device.

12. The mobile transaction processing agent system of claim 11, wherein logic for reporting fraudulent activities comprises:

logic for generating at least one of instant message, email, ringtone, or vibration to notify the user of the mobile client device.

2. The mobile transaction processing agent system of claim I, wherein the one or more mobile client devices comprise:

a user interface configured to enable a user to select a transaction type and collect a user pin number;

a processor configured to generate the secured transaction description using the transaction type and the user pin number, wherein the secured transaction description includes issuer ID, account ID, merchant ID, password, transaction amount, and transaction time stamp;

the processor is further configured to transmit the secured transaction description to a mobile processing agent for processing, and receive a transaction record from the mobile transaction processing agent; and

a memory configured to store the transaction record in the mobile client device.

13. A computer implemented method for processing secured transactions, comprising:

receiving a payment request, wherein the payment request includes a transaction description;

verifying payer account information in association with the payment request;

upon verifying the payer account information, processing the payment request;

receiving a digital signature from the payer;

upon authenticating the transaction with the received digital signature, adjusting the payer account with the transaction amount; and

sending a transaction receipt to the payer.

14. The computer implemented method of claim 13, wherein the payment request is received from a payer device or from a payee device.

15. The computer implemented method of claim 13 further comprising:

upon verifying the payer account information, sending an acknowledgement to payer.

16. The computer implemented method of claim 13, wherein the transaction description comprises:

transaction type, user pin number, issuer ID, account ID, merchant ID, password, transaction amount, transaction time stamp, and a POS GPS location of the payer device.
