Abstract:
A method for querying information in a visual smart card, comprising: a micro control unit receiving, by means of an input device, a query request inputted by a user (S1); the micro control unit determining information queried by a user request according to a received query request (S2); if first information, the micro control unit reading a first information record which is stored thereby, and parsing the first information record to obtain the first information, the first information being displayed by means of a display device (S3); if second information, the micro control unit sending an application selection instruction to a smart card chip, receiving an application selection response returned by the smart card chip, then sending an information record reading instruction to the smart card chip, receiving a second information record returned by the smart card chip, and parsing the second information record to obtain the second information, the second information being displayed by means of the display device (S4). A visual smart card applicable to said method overcomes the shortcomings in the existing technology wherein the assistance of other devices is required, while carrying out querying by means of operating a smart card directly facilitates a holder of a smart card understanding information in the smart card, improving the ease of use of smart cards.
