Security smart card using external terminal for verification and verification method thereof

Abstract

The invention relates to a security smart card using an external terminal for verification. The security smart card comprises a security chip module, a card verification sub module, a Token sub module, an I / O communication sub module, a power supply sub module, and a timing sub module. The security chip module is used for storing card information of a smart card. The card verification sub module is used for triggering a verification function of the smart card and sending a working request of turning on or off to the security chip module according to a verification result; and the timing sub module is not triggered until a working request of turning on is sent to the security chip module. The Token sub module is used for generating a verification code for verification under the circumstance that the card needs verification. The I / O communication sub module is used for carrying out data transmission with an external terminal. The power supply sub module is used for providing a power supply for the security smart card. And the timing sub module is used for carrying out timing on available time of the smart card based on triggering of the card verification sub module. According to the invention, security of the smart card can be further improved.

Description

[0001] technical field [0002] The invention relates to a smart card, in particular to a safe smart card which can be used after verification by means of an external terminal and a verification method thereof. [0003] Background technique [0004] At present, bank cards, as a commonly used payment tool for consumers, are becoming more and more practical. Therefore, there are also more and more types of risks due to cards, as follows: [0005] Risk of card loss: At present, most users put their cards in their wallets. If the wallet is lost, the user’s password is stolen through other channels due to the personal information such as ID card and work card in the wallet, or for other reasons. , The capital risk caused by the loss of the card is relatively large. [0006] Risk of card duplication: At present, for magnetic stripe cards, the technology to read magnetic stripe cards on the market is no longer a secret; for IC cards, although the encryption level is higher than ...

[0006] Risk of card duplication: At present, for magnetic stripe cards, the technology for reading magnetic stripe cards on the market is no longer a secret; for IC cards, although the encryption level is higher than that of magnetic stripe cards, there is also a risk of being read

And after being read, under normal circumstances, the user does not know, and the risk of being stolen is still high
