With IC card water meters, rural residents no longer have to run around everywhere to pay their bills.
Due to the remote locations, complex terrain, and relatively scattered user populations in rural areas, meter reading and billing tasks have become increasingly complicated. As a result, many remote mountain villages have low meter-reading coverage rates, making it difficult to collect payments. Traditionally, having plumbers visit households to collect fees is both time-consuming and labor-intensive.
Based on the rural drinking water renovation project, our company has developed an IC-card smart water meter. Using this IC-card smart water meter as a metering and settlement device for rural drinking water supply offers significant advantages.

1. The IC-card smart water meter offers convenient transactions, accurate calculations, and supports payment via mobile devices.
2. The management department has implemented a “pay first, use later” management model, addressing the issue of some users’ long-term payment arrears.
3. IC card water meters eliminate wiring issues and high failure rates.
