The prepaid amount is stored within the memory of the Smartcard.

Whenever the amount in the smart card becomes zero on power consumption, the Microcontroller turn offs all the loads by generating a buzzer sound.

The consumer has to renew the same Smartcard for further usage of power The proposed system is inbuilt with a power supply unit, a Microcontroller, smart energy meter, smart card, GSM modem and LCD.

A Microcontroller is a programmable device that includes a microprocessor, memory, I/O ports, etc., which can be evaluated with the microcomputer.

This energy meter includes an ARM7 microcontroller, LCD display, GSM module, potential transformers, current transformers and a relay.

The Microcontroller estimates the consumption of an energy by counting the o/p of current & potential transformers on the basis of an interrupt.They give an extra functionality with a real-time or near real-time reads, monitoring the power quality and power outage notification.They permit price setting agencies to initiate different prices for utilization based on the season and time of day.Robbery electricity, avoiding a meter, billing wrongdoings and not paid bills.Billing irregularity comprises wrong meter reading taken by bribed service man.It is a single chip computer and is a low cost programmable device. To know more about this, please refer the link: 8051 Microcontroller Architecture and Its Applications A smart card is a one type of integrated circuit card (ICC) and it is a pocket-sized small card with fixed integrated circuits.The smart card is made with a plastic card with a credit card size with an embedded chip that can be loaded with information.The electricity theft has appeared as a major problem in power divisions in particular in the expanding countries. In some nations this is so strict that governments are acquiring losses instead of income.In some cases government has to supply subsidies to the power division to keep a reasonable price of power.Different technical and non technical techniques were projected in the past to notice electricity stealing.Some of the technical methods to identify pilferage are utilize of central observer meter on harmonic generator, secondary terminals of distribution transformer, extreme learning machine, genetic support vector machines & a power line impedance technique.
