Can't use ic card to input electricity, display code ic-02, the property can't be solved. What should I do?

See if the contact wire of ic card is polluted. Try polishing it with an eraser. If not, go to the place where the electricity is sold and re-power it (if the data is not input into the meter within one day after the electricity purchase, the card will lock itself). If it is not the second reason, it is the problem of the electric meter, so we have to find the power supply department to check and repair it.
