What is a prepaid energy meter??

DescriptionA scheme of Electricity billing system called PREPAID ENERGY METER WITH TARIFF INDICATOR can facilitate in improved cash flow management in energy utilities and can reduces problem associated with billing consumer living in isolated area and reduces deployment of manpower for taking meter readings.Every consumer can buy a memory card (is nothing but an EEPROM IC) with a password stored inside it using a MC program

The card reader will read the stored information and delete the information from the EEPROM IC(smart card) using the MC program,so that the smart card cannot be reused by others. In our project we also have a provision to give an alarm sound to consumer before the whole amount is reduced.
