PURPOSE: A portable terminal including a near field communication module and electronic money medium are provided to enable a user to conveniently use electronic money using a valued charged in electronic medium without using a physical security module. CONSTITUTION: A proximity transaction processing unit(360) receives a payment transaction information from a payment apparatus using a proximity security channel. The payment transaction information creates information for an electronic money value reflected to electronic money medium by encoding the information. A electronic money payment authentication unit(365) encodes the encoded payment transaction information using the disposable key. The electronic money payment authentication unit authenticates the information for the electronic money value reflected to the electronic money medium. An electronic money payment processing unit(370) reduce the electronic money value of the electronic money medium through the authenticated electronic money value.
