Hi, Now online services are way of life. You get everything thro online. But involves risk also. I noticed that some banks or provider, ask for cvv and some pin codes. I recently heard that the card number could be compromised by expert hackers by so much methods. OTP is a security measure to compulsorily authorise the pay of any online services. Are all online transactions provide otp. I am having doubt . If OTP is provided for all kinds of services even involving lesser amount of transactions then there is a one more security check . Would anybody confirm that all online services provide OTP thro SMS without fail.
