A central computer(3) is a central processing unit for measuring a water supply amount, calculating a fee for the water supply amount, and enabling the user to confirm the fee. The RF-IC card(1) stores the user identification information including special numbers of the user. The measuring water supply unit(2) includes a water supply selection unit(24) having water supply on/off buttons, and deciding recognition of the RF-IC card(1), a reading unit(23) reading the user identification information stored in the RF-IC card(1) according to a signal from the water selection unit(24), a water supply amount measuring unit(21) measuring a water supply amount according to the signal from the water supply selection signal(24), a display unit(27) displaying the measured water supply amount, and a control unit(25) controlling the water supply amount and user identification information to the central computer(3). |
