The Reserve Bank of India recently banned attempts at circumventing two-factor authentication in transactions in which both payer and receiver of funds are Indians. It involved Card Not Present (CNP) transactions since it failed to fulfill the criteria of adhering to double factor authentication. These CNP transactions, had been carried out on a foreign payment gateway which involved no double-factor authentication.

For those who frequently use credit cards online, double factor authentication is a known thing. It works like this: The credit card holder fills up his credit card details on a site where he is a payer and then the bank sends him a 'one time password (OTP)' on his registered mobile phone. The transaction is completed when the OTP is entered. OTP is valid for that one transactions and expires after the use. Every new transaction made on the credit card generates a new OTP. Alternatively the credit card holder is prompted to a 'Visa or Master verified' site and then he is expected to insert his password, which is known to him only. This ensures that even if one gets to know the credit card details of an individual one cannot misuse the credit card online.

Double-factor authentication thus helps individuals from fraudulent transactions. However, recently RBI noticed that some merchant sites were involved in transactions where both parties to trade are Indians and were carrying out the transactions without two factor authentication on a foreign payment gateway to make the transactions convenient. Though no fraud is reported as of now, by banning such transactions RBI has made it clear how serious it is about insisting on double-factor authentication involved in transactions, among other factors.
