DN15~DN300 Encrypted Calibrated IC Card Prepaid Water Meter with Billing System

·Prepaid System: IC card prepaid water meters operate on a prepaid system, where users need to purchase water credits in advance and load them onto the IC card. This enables efficient management of water consumption and eliminates the need for monthly billing.

·Integrated Circuit (IC) Card: The IC card serves as a digital wallet or token that stores the prepaid water credits. It contains a microprocessor and memory chip capable of securely storing the credit balance and transaction history.

·Contactless Payment: IC card prepaid water meters typically use contactless RFID (Radio Frequency Identification) technology. Users can easily swipe or tap their IC cards near the meter's card reader to deduct the appropriate amount from their credit balance.

·Real-time Consumption Monitoring: These meters provide real-time monitoring of water consumption. The meter records the volume of water used and subtracts it from the remaining credit balance stored on the IC card. Users can track their consumption and manage their usage accordingly.

·Low Credit Warning: When the credit balance on the IC card reaches a certain threshold, the meter may generate a low credit warning to alert the user. This helps users stay informed about their remaining balance and avoid sudden water supply interruptions.
