Abstract:
    The invention relates to a tax-controlled cash register, comprising power supply, master control module, keyboard module, display module, data storage module, real-time clock module, user card module, tax-control card module, printing module, and communication interface module, where the user card module, where the user card module comprises user card power supply pins, and triode, where the emitter of the triode is connected with the power supply module, the base of the triode is connected with the master control module to control ON and OFF of the power supply pins, and a self-recovery fuse to protect the user card is connected between the collector of the triode and the user card power supply pins. It adopts self-recovery fuse to protect the user card power supply circuit, therefore, when the current exceeds the design value, the fuse will automatically break to assure not influencing the normal operations of the other module in system; and when the physical attacks are removed, the fuse will self-recover so that operation on the user card can be resumed.
