Comment on Update to CDSL's TPIN authorisation process for selling stocks
It is good way of thinking as far as security is concerned but in trade where every second matters, doesn’t make any sense of using OTP based transactions. I would suggest device authorisation should be implemented instead of OTP. Like our UPI transactions, we can perform it through our registered device only.
PIN or FINGERPRINT would be its future optimization. So this will make our transactions secure and fast.
We can not rely on server to get OTP in this scenario where Growth = Time x Money.
