ATM cards and systems have changed the lives of people. Now they have access to money all round the clock. This ease of access to money has brought forth a serious problem as well. There has been an increase in the amount of credit card frauds caused due to impersonating as the owner of the card in shops and also obtaining the PIN (Personal Identification Number) of the customer through some illegal means. The system proposed here ensures that only the authorized user can do any kind of banking transactions both in ATMs and in shops. The customers must initiate a transaction request from their mobile phones using the SMS (Short Message Service) feature that is present in all mobile phones. The customer sends a message to the bank server before he actually performs an actual banking transaction. After that he will approach either an ATM system or a shop that accepts card payments. The transaction request is sent to the bank server and hence authenticated.
