Abstract

A device and a secure element for conducting a secured financial transaction are disclosed. The device comprises a central processing unit; a communication interface for establishing a communication between the device and a financial institution related to a financial account; an interface for acquiring data relating to the financial account; the secure element for processing at least a portion of the data relating to the financial account acquired by the interface; and control logic for acquiring a purchase amount to be debited from the financial account and for obtaining a transaction authorization from the financial institution related to the financial account, the transaction authorization being based, at least partially, on data processed solely by the secure element independently of data processed by the central processing unit. A method of conducting the secured financial transaction, and a computer program product for execution by the secure element are also disclosed.

an establishment of a secured communication channel with a server of a financial institution related to the financial account through the communication interface of the device, the establishment comprising a sending, by the secure element, of a request to establish the secured communication channel by the payment control application;

a sending over the secured communication channel to the server of an authorization request to perform the secured financial transaction, the authorization request comprising at least a portion of the data relating to the financial account;

a reception over the secured communication channel from the server of a response to the authorization request; and

a processing of the response to the authorization request to generate a status of the secured financial transaction.

2. The secure element of claim 1, wherein the request to conduct a secured financial transaction is transmitted by the payment control application running on the processor of the device.

3. The secure element of claim 1, wherein the establishment of the secured communication channel comprises a sending, by the secure element, of a request to establish the secured communication channel by the payment control application.

4. The secure element of claim 1, wherein the data relating to the financial account are being processed by the secure element independently of data processed by the processor of the device.

5. The secure element of claim 1, wherein the EMV transaction module is further configured to execute a sending, by the secure element, to the payment control application running on the processor of the device of the status of the secured financial transaction.

6. The secure element of claim 1, wherein the control instructions to control the secure element comprises instructions to cause the sending, by the payment control application to the secure element, of a start payment applet message to the secure element and an activation of the secure element based on the start payment applet message.

7. The secure element of claim 1, wherein the secure element is embedded in one of a chipset embedded on a circuitry of the device, a subscriber identity module (SIM) card, a secure digital (SD) card, a non-volatile memory card, and a housing to be plugged to the device.

8. The secure element of claim 1, wherein the EMV transaction module is a contactless transaction module.

9. The secure element of claim 1, wherein the request to conduct the secured financial transaction comprises a purchase amount to be debited from the financial account.

10. The secure element of claim 1, wherein the payment apparatus is one of a payment card and a mobile device.

11. The secure element of claim 1, wherein the data relating to the financial account include at least one of a key, a certificate, and a payment card number.

12. A non-transitory computer readable storage medium comprising computer-executable instructions for execution by a secure element of a device used as a payment terminal, the device running a point of sale (POS) application, the POS application comprising a payment control application, the payment control application comprising control instructions to control the secure element, the computer-executable instructions, upon execution by a processor, causing the secure element to run:

an Europay, MasterCard, and Visa (EMV) transaction module that is configured to process data acquired by an interface of the device from a payment apparatus, the interface being a contactless interface configured to receive data contactlessly from the payment apparatus;

an operating system (OS) configured to process data provided by the EMV transaction module;

wherein the EMV transaction module is configured to execute;

a reception of a request to conduct a secured financial transaction;

an acquisition, by the secure element, via the interface of the device, of data relating to a financial account from the payment apparatus, the acquisition comprising (i) a sending of a Select Proximity Payment System Environment (PPSE) request to the payment apparatus, (ii) a receiving of a response from the payment apparatus indicating payment applications supported by the payment apparatus and (iii) a selection of a payment application amongst those available;
