In this embodiment, when the power adapter 11 is normally connected to the power supply, the main board 13 outputs pre-stored commodity data and price information to the storage unit 181 for storage, so that it is ensured that the intelligent transaction terminal can still obtain the commodity data and price information through the display module 18 in a passive state, and thus the weighing and pricing operation is completed; however, in another embodiment of the present utility model, the storage unit 181 may store commodity data and price information in advance.
In some embodiments, the storage unit 181 receives and stores the commodity transaction record output by the microcontroller 14 in the no-power state, and after the power adapter 11 is connected to the power, the storage unit 181 sends the commodity transaction record to the main board 13, so that the user can still normally transact and record transaction data in the power-off state.
