Astra Card Prepaid Water Meter
The system is based on the principle that the water consumptions are calculated, and consumers are charged accordingly in advance. Consumers spend the amount of water loaded from credit sales offices
by loading the credit to water meters via smart cards. The water meter cuts off the water by closing its valve when the credit ends, but when the consumer re-loads the spare credit in smart card to the water meter, the valve will re-open. Spare credits function allow consumers to use water until they re-load the smart card.
