Mobile Phone Based Secured Electronic Payment System Using RFID Communication

Abstract

This paper proposed an advanced ATM card security system using GSM. In which the owner controls the ATM transactions done by his assistant. The owner can give the password through SMS rather than sharing the password. This is made possible by adding the GSM technology to the ATM Machines. The ATM Machine is programmed to provide an option by getting Password through SMS. Whenever the user flash the ATM card in RFID, the machine ask the primary password, this password is entered through the keypad, if the password is correct, the card owner will get an SMS asking for the secondary password. The owner sends the secondary password through SMS. This secondary password has dynamic change OTP. The machines checks for the password and processes the further transaction. If any theft finds in this transaction automatically the GSM modem send the SMS to card owner and police. Then ATM CARD automatically blocked and it generates the alarm when theft occurred.
