The water meter can transfer 20-digit Token to the water meter terminal through wireless or keypad to realize water recharging. It realizes the change from the original staff's door-to-door meter reading and charging to the user's automatic payment, and puts anend to the phenomenon of malicious delinquency in water charges.
