<p>Provided are a smart card and a transaction control method for the smart card. The method comprises: a smart card chip (101) receiving a transaction instruction from a card reader (20) via an antenna (102) (S201); parsing the transaction instruction, so as to acquire transaction information (S202); judging whether the transaction information contains information about amount of money or not (S203); if the transaction information contains the information about amount of money, comparing a pre-stored first threshold value with the information about amount of money (S204); if the comparison result indicates that the information about amount of money is less than the first threshold value, executing a transaction operation according to the transaction instruction (S205); if the comparison result indicates that the information about amount of money is greater than or equal to the first threshold value, sending first comparison information to a security chip (103) (S206); the security chip (103) executing a verification operation according to the first comparison information, and sending information that verification has passed to the smart card chip (101) after completing the verification operation (S207); and the smart card chip (101) executing the transaction operation according to the information that verification has passed and the transaction instruction (S208).</p> |
