Portable object including a display and application for carrying out electronic transactions

A method for performing an electronic transaction comprising an exchange of data between a remote processing unit and a portable device, the portable device comprising a security component and being connected to an interactive display, wherein the portable device is configured to make interactive transactions with the remote processing unit, through the interactive display and under control of the security component, said method comprising the steps of:

• displaying, by the interactive display, all or some information useful to the transaction to a user,
• receiving input, in response to the displaying step, wherein the input is received via said interactive display,
• securely receiving a personal identification number (PIN) code or biometric data in the security component while connected to a terminal that is in communication with the remote processing unit,
• authorizing a transaction by verifying the personal identification number (PIN) code or biometric data by the security component in the portable device while connected to the terminal,
• receiving information useful to the transaction from the remote processing unit through the terminal, and
• displaying the information received from the remote processing unit on the interactive display, while the portable device is connected to the terminal.

A system for performing an electronic transaction including a bidirectional data exchange between a remote processing unit and a portable device, said system comprising:

• a terminal configured to communicate with the portable device;
• the remote processing unit;
• and
• the portable device, comprising a security component connected to an interactive display, and configured to:
• receive a personal identification number (PIN) code or biometric data securely in the security component while the security component is connected to the terminal, wherein the terminal is in communication with the remote processing unit,
• authorize a transaction by verifying the personal identification number (PIN) code or biometric data by the security component in the portable device while the portable device is connected to the terminal, and
• make interactive transactions with the remote processing unit, through the interactive display and under control of the security component,
• wherein the interactive display is further configured to receive information useful to the transaction from the remote processing unit through the terminal, and display the information on the interactive display, while the portable device is connected to the terminal, and
• wherein the displaying of information and an interaction with a user are performed via said interactive display.
