Abstract—Secure ATM transactions provide a foundation for the ATM industry. To maximize ATMs’ effectiveness and profitability, card users must feel safe and the ATM’s vault must be secure from theft. Now a days by swiping the card which we are having and by entering the password, we are accessing our bank account. If card is missing means there is a chance for malfunction. To overcome this we are proposing a new method in this project. After swiping and entering the password, if the password matches means the ATM machine will send alert message to the corresponding account holder. When the machine receives acceptance message from respective account holder it will allow accessing the account. If the acceptance message not received the access will be denied. To achieve this we are using Global System for Mobile Communication (GSM) technology. The microcontroller which we are using is a mid range PIC microcontroller. For scanning we are using IR based sensor setup. If any miss use of card, the system automatically informs both user and the bank manager by sending the SMS to the user and buzzer alert system to the manager through wireless communication called RF.
