Bank ATM Security System

Bank ATM Security System

Introduction:

User ATM security is the prime concern for every bank as it helps banks to achieve customer satisfaction and provides opportunities for them to grow their business. The user always looks for a bank which provides him the safe and secure banking solutions with minimum risk factor. This Bank ATM Security System provides security for the user ATM’s provided by the banks. For this, it takes the help of GSM Technology, each use will have a unique code for ATM transaction. User needs to enter the code while opening the ATM the security system and it generates a unique encrypted code for user access and sends SMS  to user with the help of GSM module attached, user needs to enter this code in order to open the account in an ATM within a specific time frame, otherwise the system locks the door and denies the access.

Project Description:

Micro-controller This is the most important segment of the project, i.e. the micro-controller 8051 The controller is responsible for detection and polling of the peripherals status. It is responsible for making. It is responsible for prioritizing all the devices attached to it.  We have used the ATMEL 89s51 micro-controller. The AT89S51 is a low-power, high-performance CMOS 4-bit micro-controller with 8K bytes of in-system programmable Flash memory. It has got 32 I/O lines, Watchdog timer, two data pointers, two 16-bit timer/counters, six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and a clock circuitry.
GSM ModemGSM module is used to establish communication between a computer and a GSM-GPRS system. Global System for Mobile communication (GSM) is an architecture used for mobile communication in most of the countries. Global Packet Radio Service (GPRS) is an extension of GSM that enables higher data transmission rate. GSM module consists of a GSM  modem assembled together with power supply circuit and communication interfaces (like RS-232, USB, etc) for computer. The MODEM is the soul of such modules.
Mobile Phone  
 In this project we have used one cell phones for user to send SMS with unique password. The cell phone will use GSM Network for communication
Keypad:
We have used 4*4 keypad interfaced with the microcontroller, so that use can enter his ATM number and other mandatory information.
Door Motor and Alarm Circuit: 
We have used a DC motor for door and a buzzer in order to raise an alarm signal.

Advantages

  1. Bank ATM Security System provides a high level of security using GSM technology. 
  2. Security is ensured even if the unauthorized user tries to open the ATM with the valid user id, as the encrypted code will only be sent to valid user cell phone
  3. Low cost, easy to use
  4. System can be easily modify for new users

Applications

  1. Bank security system
  2. Personal ATM Security System
  3. Jewellary Stores

AGRO ELECTRONICS SYSTEM: Appropriate environmental conditions are necessary for optimum plant growth, improved Crop yields, and efficient use of water and other resources. Automating the data acquisition process of the soil conditions and various climatic parameters lead to plant growth to collect information at high frequency with less labour requirements.       In order to prevent dry running of motor and allow automatic restart of motor, sufficient water level is regained. Whenever water falls below LL level, micro-controller switches OFF the motor and sends SMS indicating dry running conditions. When the water rises beyond HL level, the micro-controller switches ON the motor again and sends sms indicating resumption of task. User need to go again and again and check the water level, he will get the alerts automatically whenever water is below the HL level.        In order to ensure maximum reliability, one temperature senso...

Voice and GSM Alert Based Home Security System

Voice and GSM Alert Based Home Security System: Introduction: Home security in India has been a major issue, because day by day crime rate is increasing and everybody wants to take proper actions to prevent this crime rate. In addition, there was a need to take the advantage of the technological advancement to automate home so that a person getting off the office does not feel insecure. The project is aimed at developing the security of Home against Intruders , Gas Leak and Fire . If any of these cases happen while your are outside the home, this  Voice and GSM Alert Based Home Security sends SMS to the emergency number provided to it. User can also add unique voice based alert feature in order to provide voice alert to watchman or nearby houses. Block Diagram: Project Description:   In this project we interfaced 8051 microcontroller with Motorola’s C168 GSM mobile phone to decode the received message. The protocol used for the communication between th...

Wireless Automatic Meter Reading System for Power Measurement, Load Control and Billing

Wireless Automatic Meter Reading System for Power Measurement, Load Control and Billing:   Introduction Due to use of  improper power management systems, the power requirement is increasing in the development of country’s economy. Over the past years, metering devices have improved a lot, and are expected to become even more advanced, offering more and more services. Meters in the past were electro-mechanical devices with poor accuracy and lack of ability. Recent developments in this direction seem to provide opportunities in implementing energy efficient metering  technologies that are more precise and accurate, error free, etc. The implementation of Wireless Automatic Meter Reading System(WAMRS) provides with many vital features as compared with the analogue utility meter reading with man power. Working of WAMRS: WAMRS provides a two way communication between the electricity company and the load by sending in a lot of power parameters and control s...
