Problems solved by technology

[0005] It can be seen that continuously sending multiple instructions of the same operation to the smart card requires a corresponding number of interactions between the terminal and the smart card, which makes the interaction process cumbersome. Due to the excessive number of interactions, the interaction time is longer and the processing efficiency is reduced.

Embodiment Construction

[0029] In order to reduce the number of interactions between the terminal and the smart card, further reduce the occupied interaction time, and improve processing efficiency, the embodiments of the present invention provide a smart card operation method, a smart card, a terminal, and a system.

[0030] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] as attached figure 1 As shown, in the embodiment of the present invention, the system for operating a smart card mainly includes a terminal 10 and a smart card 11, wherein,

[0032] The terminal 10 is used to combine at least two application protocol data unit (APDU) commands for performing continuous similar operations on the data of the smart card 11 into one special APDU command for corresponding operations, and send the special APDU command to the smart card 11 ;

[0033] The smart card 11 is used to receive the special APDU command sent ...

Abstract

The invention discloses a method for operating a smart card. By adoption of the method, the interaction frequency of a terminal and the smart card is reduced, the interaction time of the terminal and the smart card is shortened, and processing efficiency is improved. The method comprises the following steps of: receiving a special application protocol data unit (APDU) command, wherein the special APDU command is formed by combining at least two APDU commands which are used for performing continuous similar operation on data of the smart card; and according to a predefined data domain format in a command body of the special APDU command, analyzing the command body of the special APDU command, acquiring corresponding data, and performing corresponding operation on the smart card. Meanwhile, the invention discloses the smart card, the terminal and a system for operating the smart card.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a smart card operation method, smart card, terminal and system. Background technique [0002] Smart cards have been widely used in many fields such as telecommunications, transportation, and finance. In a complex transaction process, it may be necessary to frequently read data in the smart card or write data in the smart card frequently. That is to say, the terminal may need to send many read file commands to read the data in the smart card; or, the terminal sends many write file commands to write data in the smart card, which results in a longer interaction time between the terminal and the smart card. For example, in the financial field, according to the EMV protocol, after the transaction is initialized, the terminal is required to send multiple read file commands. [0003] Similarly, if the terminal needs to update a large number of files in the smart card, the terminal ...
