As an investor, you may wonder as to why you are asked to identify yourself. That is again for your own safety. This will ensure that nobody can open the demat account on your behalf. Today we have seen cases where Aadhar data has been hacked and has also been leaked. Such risks can be controlled through in-person verification (IPV).
As a last step, you are still required to do a second level of verification. This can either be done by video camera fitted on your PC or through an in-person-verification (IVP) at the nearest customer point of the DP. Quite often what brokers do is to allow you to operate up to a certain limit on your demat and trading account without IPV but if you want to really scale up your volumes and your investments then IPV is a must.
