WORKING

• In our project we have given the name for memory
  card as smart card. When the consumer insert a
  smart card into the card reader which is
  connected in prepaid energy meter with tariff
  indicatorkit.Then 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. Suppose if a consumer buy a card for
  Rs.50/- he / she can insert this amount through
  the card reader so that prepaid energy meter with
  tariff indicator kit will be activated. According
  to the power consumption the amount will be
  reduced. When the amount is over, the relay will
  automatically shutdown the whole system.
