A fault in the EMV protocol used in Point Of Sale (POS) terminals and Automated Teller Machine (ATMs), for authenticating credit and debit card transactions allows attackers to make fake transitions. EMV protocol is a joint venture of Europay, MasterCard and Visa to ensure security and global interoperability so that Visa and MasterCard cards can continue to be accepted everywhere.researchers make advantage of the poor encryption standards used in ATM Machines.Using the EMV protocol, atm machines and similar devices generate  a unique number for the transaction Here the researchers found a fault in the software which make the unique number in the machines and they prove that one can predict the random number generated for transactions.simply any one  who stolen your ATM Card can make transactions using your card.
