IC cards serve as the data carriers to enable automatic payment functionality；

The management department writes the user's payment information onto the IC card. When the card is swiped, the water meter automatically supplies water and calculates the remaining balance. Once the prepaid amount is used up, the valve closes to cut off the water supply. Water service is restored only after the user purchases credit again；

The products feature power supply options including dry cell batteries and lithium batteries, as well as billing methods such as single-rate and tiered-rate pricing. These versatile products have been successfully deployed nationwide across a wide range of applications.
