INTRODUCTION

Token display systems are ideal for banks, airports, public dealing offices, hospitals, doctor’s clinics, restaurants and other such places where people have to wait in line for their turn.

A digital token is issued by cashier in bank.

Thus the device serve the purpose of improving the performance of the banking system.

WORKING….. The project works on 5V DC.

PRESS * - For getting new Token.

PRESS 1 -NEW A/C

PRESS 2 -NEW F/D

PRESS 3 -NEW S/A

PRESS 4 -FOR INQ

Then user has to press the relevant number for issue of the token.

The data is stored in EEPROM.

CIRCUIT COMPONENTS

POWER SUPPLYMICROCONTROLLER AT89S52MAX232EEPROM4x3 KEYPADLCD

POWER SUPPLY

Transformer: steps down ac voltage Rectifier: converts AC to varying DC.

Smoothing: smooth the AC to DC, ripples are there.

Regulator: delivers fixed dc output without ripple

AT89S52

Features:-

8K Byte of In-System Flash memory Fully static operation:0 to 24MHz 256 x 8-bit internal RAM 32 programmable I/O lines Three 16-bit Timer/Counters Eight Interrupt Source Watchdog Timer Dual Data Pointer

MAX 232

Features:-

Operate from a single 5-v power supply with 1.0- μF charge-pump Capacitors.

Operates up to 120 Kbit/sTwo drivers and two receivers±30-v input Level-receiverLow supply current(8 mA-typical)

Application--- Modems and Computers

EEPROM

ST24C02 Electrically Erasable and Programmable Read Only memory is used, so that information is not lost even when power is off.

4x3 KEYPAD

4x3 Keyboard is used for entering the data.

LCD

20x4 lcd and 16x2 lcd are used for display the messages and Token.

LED

Led blinks to indicate system is operational.

SOFTWARE DESCRIPTION

BASCOM-8051

Introduction:-

BASCOM-8051 is not only a BASIC Compiler, but also a comfortable Integrated Development Environment (IDE) running under Windows. Such a development environment supports the whole process from coding and testing a program to programming.

Developing order

•Start BASCOM;•Open a file or create a new one;•Compile the file;•If an error occurs fix it and recompile (F7);•Run the simulator;•Program the chip;

ADVANTAGES

Token Display System is a project liable to be used at the places where people have to wait in line for their turn. These systems allow customers to wait without having to stand in line.

All models are easy to install, operate & maintain. Any ordinary electrician can do the installation quickly.

DISADVANTAGES

The system is controller based so any modification you want to do only skilled person can do it.

Lcd is not suitable for outdoor and industrial application.

APPLICATION

Token display systems are ideal for Banks Airport Hospitals Restaurants Public dealing offices

CONCLUSION

With the help of the available resources & components, we succeeded in the development of ‘BANK TOKEN ISSUE SYSTEM’, which is truly unique in its place.

 The project is so much cost effective and result oriented.
