ABSTRACT:
The present invention relates to a contactless card in smart card field and a control method thereof. The contactless card comprises a card chip, an antenna resonant circuit, and a confirmation unit. The confirmation unit, being separated from the antenna resonant circuit and connected to the I/O interface of the card chip, is used for confirming a card operation command by a cardholder so as to send a confirmation message to the card chip. The control method can be realized according to the following steps: putting a contactless card into a valid range for its reader; determining by the contactless card whether a command transmitted from the reader needs to be confirmed by the cardholder, if not, responding to the command by the contactless card, otherwise waiting for confirmation message by the contactless card; and receiving the confirmation message from the cardholder and responding to the command by the contactless card. The present method provides the cardholder with the light on the control of command execution and prevents the information stored in the card from being stolen or mis-operation to the card, which improves the usability of the contactless card and eliminates the impedance and enhances the continuity of the antenna resonant circuit and brings the convenience to the cardholder.
