Abstract

The invention discloses an intelligent card firmware updating method and system. The method comprises the steps that a cloud server receives a first firmware updating request sent by a terminal, wherein the first firmware updating request is used for indicating the cloud server to generate first firmware, the first firmware is used for performing read-write operation of a first meter in an intelligent card bound with the terminal, and the first firmware updating request comprises an identifier of the first meter and an identifier of the intelligent card; the cloud server determines a dynamic link library file of the first meter according to the identifier of the first meter, and determines original firmware of the intelligent card according to the identifier of the intelligent card; the first firmware is generated according to the dynamic link library file of the first meter and the original firmware of the intelligent card; and the generated first firmware is sent to the terminal, so that the terminal downloads the received first firmware in the intelligent card and current firmware of the intelligent card is updated to the first firmware. Therefore, firmware used for performing read-write operations of chips of intelligent cards can be quickly matched with the intelligent cards for different application scenes.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a method and system for updating firmware of a smart card. Background technique [0002] The smart card communicates with the mobile terminal to realize new functions. For example, a smart card with bluetooth function can communicate with a mobile phone through a bluetooth module, enabling users to recharge the smart card through the mobile phone, so that the user does not have to go to the business hall to recharge. maintenance costs. [0003] Smart cards with Bluetooth function cannot exist alone, and must be used in conjunction with meter manufacturers (such as gas meter suppliers) and data backgrounds (gas company data backgrounds). Different meter manufacturers have different data read and write operations on smart cards, and the communication security methods between smart cards and different meter manufacturers are different (different...
