In a span of a month, 2,000 is the figure on everyone’s head. After launching the new currency note of Rs 2,000 denomination, the RBI relaxed the much needed one time password (OTP) to authenticate all card transactions rule by making transactions up to Rs 2,000 to have an optional OTP. In India, online transactions have a two factor authentication. So when you are using a credit or debit card to make an online payment, you enter your card number and your CVV number, which is the first level of authentication and then you are sent a one-time password on your phone which you need to put in to complete the transaction.
