The invention discloses an application data
backup recovery method of an intelligent card, an electronic device and a storage medium, wherein, the intelligent card comprises a
smart card chip and an MCU module. The method comprises: if an application data
backup instruction is detected, the application data in the
smart card chip is saved in the MCU module according to the application data backupinstruction; if the application data
backup instruction is detected, the application data in the
smart card chip is stored in the MCU module. If the application
data recovery instruction is detected,the application data in the MCU module is read into the smart card chip according to the application
data recovery instruction. The invention provides an application data backup and restoration methodof a smart card,
ELECTRONIC EQUIPMENT AND STORAGE MEDIUM, when an application data backup instruction is detected, The application data in the smart card chip is backed up to the MCU module, and whenthe
data needs to be recovered, the application data in the MCU module is read into the smart card chip according to the
recovery data instruction, thereby avoiding the problem that the important
data loss in the application caused by deleting the application in the smart card causes the loss to the user.
