<p>PURPOSE: A security medium for requesting transaction permission and a payment system using the security medium by using a payment button are provided to prevent payment through the security medium if a payment button of the security medium is not worked, thereby fundamentally blocking attacks from viruses or hackings. CONSTITUTION: A connector(111) is an interface for code input or output with a computer. A smart card controller(112) transmits and receives codes with the computer connected to the connector. A payment button(113) is connected to the smart card controller. If a payment request code is received from the computer connected to a payment server, the smart card controller transmits a payment permission code to the computer in case the payment button is worked.</p> |
