The prepaid water meter system consists of a prepaid water meter, an IC card, a card reader, and management software. Smart Ic Card Digital Prepaid Water Meter With Software adopts a one-meter one-card system.
Simply install the software on your computer and the card reader is connected to the computer via the USB interface to transfer data to the IC card. The user brings his IC card to the management center to pay the fee. After the payment is successful, the card is placed close to the water meter. After the card is successfully read, the water can be used.
