The function of limiting the use of one card per meter for prepaid water meters mainly relies on its internal advanced technology and design.
Core technology: The microchip inside the prepaid water meter realizes the rapid identification and processing of user information through a highly integrated circuit design. This chip can efficiently process various data to ensure the response speed and accuracy of the water meter. The high-precision sensors built into the water meter can monitor parameters such as water flow and water pressure in real time to ensure the accuracy and reliability of measurement. These sensors also have self-calibration and correction functions, which can maintain stable performance in long-term use. By adopting stored-value card technology, users can pre-charge water fees on the card and then insert the card into the water meter for consumption. This technology not only facilitates user use, but also improves the efficiency and security of water fee collection.
One meter, one card function is realized: When the user inserts the issued smart water card into the water meter, the prepaid water meter will automatically identify the user's unique code through the built-in IC card reader and save it. The next time the user inserts the card again, the water meter will automatically recognize the code and match it with the previously saved information, allowing the user to use water normally. If the user tries to insert other unauthorized cards, the water meter will not be able to identify or match them, and will refuse to provide services, effectively preventing the use of illegal cards.
Data security and protection: The prepaid water meter uses advanced logical encryption technology to ensure the security and reliability of user data. In the event of a power outage, the data storage mechanism inside the water meter can ensure that the data is kept for up to 10 years. Even if the water meter is not used for a long time or encounters a power outage, the user data will not be lost.
Waterproof and sealed design: The water meter adopts a fully sealed shell design, which completely encloses the core components such as internal electronic components and sensors. This design effectively prevents interference and damage from external environments such as moisture and dust. The water meter uses contactless card technology, allowing users to perform operations such as recharge and query without opening the case during operation. This technology not only improves the user's convenience, but also further enhances the waterproof performance of the water meter. The outer shell of the water meter is made of waterproof materials and special waterproof process treatment to ensure that it can still work normally when fully immersed in water. This design effectively prevents the water meter from leaking in harsh environments.
In summary, prepaid water meters use advanced identification technology, data storage mechanism and waterproof sealing design to achieve the function of limiting the use of one card per meter, effectively preventing the use of illegal cards and ensuring the security and reliability of user data.
