ABSTRACT
A scheme of prepaid card for SHOPING MALL system can facilitate in improved cash flow management in various product utilities and can reduce problem associated with deployment of manpower for collecting bills. Every consumer can buy a memory card (is nothing but an EEPROM IC) with a password stored inside it using a MC program. The memory card is available at various ranges (i.e. Rs 50, Rs 100, Rs 200 etc…).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 to tariff indicator. Then the card reader will read the stored information and delete the information from the EEPROM IC 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 tariff indicator kit will be activated. According to the fuel consumption the amount will be reduced. When the amount is over, the relay will automatically shutdown the whole system. In our project we also have a provision to give an alarm sound to consumer before the whole amount is reduced.
The complete project is built around the 8051 micro controller. PCB Wizard Schematic generation software is employed to prepare the schematic for development of project. Hardware is built according to schematic prepared by soldering each component on the general purpose PCB. Source code is developed using Keil micro vision software. µVision is an IDE (Integrated Development Environment) that helps you write, compile, and debug embedded programs. The written source code is dumped into the microcontroller IC using a Programmer. To dump the code into microcontroller micro C Flash software is used.
