Take integrated circuit card(IC card)as to pay the bill with the control medium complete digitized intelligence electronic metering device.It's a new generation of products,it has the complete digitized electrical energy measurement,the intellectualized charge control and the user information management the multi-purpose functions and so on. And it is an ideal product on the current situation of reforming electric power consuming system,commercializing electric power,solving the problem of the collection of charges,as well as adjusting load state of electrical network.

System Configuration: 1.Prepaid Meter 2.Card Reader 3.Prepayment Software     Working principle:  1. Both-way electric energy metering: provides precise positive-negative active energy metering and one-way accumulating; used for power metering and advance purchase of AC single-phase current rated 2. Advance purchase quantity, preset maximum load-limit and IC card password; IC card transfers data and realizes data including total consumption, remaining quantity, accumulated quantity and total purchases) backward reading 3. Storage of leave-factory serial number, meter constants, initial data and the user's name and address  4. Alarm and switch off when overload; alarm at low remaining power to remind user of timely purchasing
