The project aims in designing a security system which makes ATM transactions more secure than existing ones. The biometric authentication is added to the ATM terminal and security alert the customer and bank authority, if tried to access with wrong finger prints three times using GSM technology. Identification and verification of a person today is a common thing; which may include door-lock system, safe box and vehicle control or even at accessing bank accounts via ATM, etc which is necessary for securing personal information. The conventional methods like ID card verification or signature does not provide perfection and reliability. The systems employed at these places must be fast enough and robust too. Use of the ATM (Automatic Teller Machine) which provides customers with the convenient banknote trading is facing a new challenge to carry on the valid identity to the customer. Since, in conventional identification methods with ATM, criminal cases are increasing making financial losses to customers. The aim of the project is to present a card less Transaction in ATM using OTP. The design can be implemented with microcontroller. The interfaced devices to the microcontroller are Fingerprint Module, GSM, LCD , Control Buttons and Buzzer. ATM system using GSM is an advanced ATM system where advanced security is provided for the user while withdrawing cash. Whenever a customer or an account holder scans his/her finger for ATM then a OTP(one time password) will be sent to the customer registered mobile number through GSM modem, the customer in turn needs to forward the same code to the GSM modem to withdraw the money, once the code is forwarded by the customer, the controller checks the received code with the generated code, if matches it asks for the amount to be withdrawn, after the transaction, the remaining balance will be again sent to the customer registered mobile number via GSM modem and correspondent data will be displayed on the LCD. By using control buttons user can enter the amount and also store/delete the finger prints into the fingerprint module. The main controlling device of the project is PIC18F452 microcontroller which is loaded program written in embedded C language. The status of the project is display on LCD.

   

The main features of the project are:

• Real time authentication system using finger print module.
• Audible alerts using Buzzer.
• Visible alerts using LCD display.
• GSM based SMS and OTP alerting system.
• To achieve this task using PIC18F452microcontroller.
