CONTENT

In this system we have introduced a Shopping Card for the Customers that will facilitate them while shopping.

This new system will help in making the buying and selling process more effective and accurate.

INTRODUCTION

Every Customer upon his arrival in the Mall will receive a shopping Card that will contain a ID Number.

The Customer after buying an item from a particular shop will give his Shopping Card to the Seller.

The Seller would then track the price of the item through a bar-code reader and update it in the System on the ID i.e. allotted to the customer.

Method of Usage

Method of Usage

After completing his shopping, the customer can later proceed to the main counter where he would pass the Shopping Card to the Cashier.

The cashier, after entering the ID in the system/software developed, will get a list of the items bought and their prices and would make the total bill.

The Customer has the option to either pay the bill in Cash or through a Credit Card.

SHOPPING ID CARD

Hardware

The hardware used:

o A bar code reader

o LED’s

o Printers.

o One server with all devices that are connected through LAN networking.

o Computer Systems

o Networking Cables

o Power Supply

HARDWARE

Types of Memory Used

There are three types of Memory:

a) CODE MOMERY

Code memory is the memory that holds the actual programs that is to be run. This memory is limited to 64Kb. Code memory may be found on-chip or off-chip.

b) FLASH MEMORY

Flash memory (sometimes called "flash hard disk") is a type of constantly-powered non volatile that can be erased and reprogrammed in units of memory called blocks.

Types of Memory Used

C) INTERNAL RAM

The program have a bank of 128 bytes of internal RAM. The internal RAM is found on-chip.

It is the fastest Ram available.

CONT..

FLASH

Low-cost, high-density, high-speed architecture; low power; high reliability

ROM Read-Only Memory

High-density, reliable, low cost; time-consuming mask required, suitable for high production with stable code

SRAM Static Random-Access Memory

Highest speed, high-power, low-density memory; limited density drives up cost

EPROM Electrically Programmable Read-Only Memory

High-density memory; must be exposed to ultraviolet light for erasure

Features of Memory

Hardware Explanation

A controller consists :

o Powerful CPU tightly coupled with memory

o Various I/O interfaces such as serial port

o If a system is developed with a microprocessor, the designer has to go for external memory such as RAM, ROM, EPROM and peripherals.

o But controller is provided all these facilities on a single chip.

o Parallel port timer or counter

o Digital to Analog converter, integrated on to a single silicon chip.

FURTHER HARDWARE

The software used include:

1. Microsoft Visual Studio.

2. Eclipse.

3. Microsoft Excel.

SOFTWARE

Function of Software

o Arithmetic Instructions: These instructions perform several basic operations (addition, subtraction, division, multiplication etc.) After execution, the result is stored in the first operand. For example:

o Data Transfer Instructions: These instructions move the content of one register to another one. The register which content is moved remains unchanged.

FUNCTION OF SOFTWARE

How this Software works?

All Employs will have a unique ID and password which they get by registering to software when they you first time.

Without ID no one can use this software.

There are 2 different things in this software.

1. Administration’s Account.

2. Non-Administration’s Account.

Both account have different features.

Functionality

TIMERS

o On-chip timing/counting facility has proved the capabilities of the microcontroller for implementing the real time application.

o These includes pulse counting, frequency measurement, pulse width measurement, baud rate generation, etc,.

TIMER
