K.L. Kannan · 2013
In this project a highly secured ATM transaction system has been developed with the help of visual basic programming and Embedded C. The authenticator (Bank) generates a random number and provides that to the card user whenever the user inserts his card on the ATM machine. The random generated code will be send to the card user with the help of GSM technology. The user can provide this code on the ATM machine and can continue his transaction. Whenever they entered code gets wrong the door of the ATM machine gets locked and security alarms will bang. This system will help the user to secure his transaction and prevents the unauthorized usage of the card.
