Abstract

The electric power meter shall find application for IC card payment type for gas and water meter, the credit value of the IC card is transferred and stored in off-line state. The measuring of the value of the electric power and the extra cost is made quickly and in an easy manner. It is convenient for the user and reduces considerably all prices. The server of the supplier, seller or distributor of electric power transfers value through an electric power line through a built-in electric power modem, stores value received through a modem in a value store module, reduces a value according to the amount of electric power consumption, no need being of processes for the visual reading a meter, calculation of the amount of consumed power, printing and mailing of bills, setting up and paying of uncollected amount and arrears. Accordingly it is possible to save electric power supplying costs, to reduce the electric power rate by a user, and maximizing the profit of the electric power supplier. By the memorizing electric power meter a method for transmitting and memorizing of values is realized. 17 claims, 7 figures
