INTRODUCTION
An embedded system is a combination of software and hardware to perform a dedicated task.
Some of the main devices used in embedded products are Microprocessors and Microcontrollers.
Microprocessors are commonly referred to as general purpose processors as they simply accept the inputs, process it and give the output.
In contrast, a microcontroller not only accepts the data as inputs but also manipulates it, interfaces the data with various devices, controls the data and thus finally gives the result.
Security is the condition of being protected against danger or loss. In the general sense, security is a concept similar to safety. The word "security" in general usage is synonymous with "safety," but as a technical term "security" means that, something not only is secure but that it has been secured. One of the best options for providing good security is by using a technology named EMBEDDED SYSTEMS.
Abstract
The advent of technology is increasing day by day. Man stopped carrying money purses or wallets with them wherever they go. Instead, they started carrying Credit Cards, Debit Cards and ATMs. They carry on with their shopping and pay the bill amounts using these cards. Thus, these cards have become a part of human life. But, if a human loses this card, the loss cannot even be imagined. When the technology brings out a new invent into light, the invent has its own advantages and disadvantages. As an engineer, it is our responsibility to use the technology in a right way at the best.
This project has been designed as a real time application to trace out the lost ATM cards. Whenever the user inserts his ATM card into ATM machine, a message will be sent to the user providing the details like time of card insertion, date, place where the card has been inserted. This database will be maintained both in the bank and at the ATM center.
Whenever any user loses his ATM card, he puts a complaint in the bank just by sending message. When this lost card if placed in the ATM center by any person other than the user, the card details will be immediately sent to the actual user and near by police station. And siren also gets activated and in this case the ATM door also closed to catch that person.
