Prepaid management system（domestic type, one card for one meter）
This system is a pre-paid system for water management. After each user pays the water fee in advance at the designated management office, he/she will take the IC card with the water purchased information home, insert the IC card into the water meter or put it in the induction area, and the water purchased information can be imported into the meter, and the water meter will open the valve to supply water. When the water allowance in the meter is zero, the valve is closed and the water is cut off. The water can be used only after the meter is recharged. When purchasing water each time, the IC card can brings the user's water consumption information back to the management software, which can record, inquire, analyze and make statistics on the data. This system solves the problem of meter reading and charging for water management industry.
