ABSTRACT
The main aim behind making this project is to make a system of security in which card is the identity of user like ATM . But In case of ATM and other electronic cards we have to store some information In the cards (i.e. in magnetic strip , bar code etc.) . In this project it is shown that without storing any information to the card how it can be identified . We have implemented by identifying the patterns present in the card using IR Leds and PhotoTransistor .
In this project a pair of IR led and Phototransistor is placed in front of each other . There is a passage of IR rays between the pair which when obstructed by some thing can be sensed by microcontroller . Here we have set 3 pair of IR led and phototransistor . so they will have total 8 combinations of states which are assigned identity according to our choice . In this way the cards are identified just by their construction and not by any information stored in the card .
To implement it Professionally , it need some modifications , But can be safely and easily used for security purposes in offices , workstations , hotels etc. and also for providing different access rights or services to different people .
This project is developed using Atmel 89S51 microcontroller and the programming is done in C language on Keil uVision 4.0 software .
Significance of Project :
This project can be used in house , offices , warehouses , colleges etc in which security and record is a concern .It can be mainly used in the areas where only authorized access is allowed . Every authorized person has its own Identity Card through which it is recognized by the system . All the functions are controlled by the 8051 microcontroller . It uses IR sensors and detectors . Every card is first inserted in provided slot then checked for its access . If validation of card expired then no access . After checking if the card is found valid , access is allowed to it .
Introduction :
An identity document (also called a piece of identification or ID, or colloquially as one's 'papers') is any document which may be used to verify aspects of a person's personal identity.
If issued in the form of a small, mostly standard-sized card, it is usually called an identity card (IC). In some countries the possession of a government-produced identity card is compulsory while in others it may be voluntary. In countries which do not have formal identity documents, informal ones may in some circumstances be required.
In the absence of a formal identity document, some countries accept driving licences as the most effective method of proof of identity. Most countries accept passports as a form of identification.
Most countries have the rule that foreign citizens need to have their passport or occasionally a national identity card from their home country available at any time if they do not have residence permit in the country.
Presently there are many types of cards available such as punch cards, magnetic cards, optical cards but all are having the disadvantage of performance degradation as we use them.
