Abstract
The present disclosure provides a smart card information querying method, including: sending a terminal configuration request to a server, so that the server determines, according to the terminal configuration request, whether a terminal configuration file cached in a terminal needs to be updated, wherein the terminal configuration file is configured based on a geographical area indicated by a smart card and is used for querying smart card information; receiving an update file delivered by the server, when the server determines that the terminal configuration file cached in the terminal needs to be updated; updating the terminal configuration file cached locally according to the update file delivered by the server; and when a connection is established to the smart card in a short-distance communications mode, querying card information of the smart card according to the updated terminal configuration file.
