Sorry for making this request again. It is all right to print the form etc. and courier it back to you for the purpose of account opening. But Sachin/Zerodha, should not be in this technological age small-small things like this one page consent letter or enabling BSE trading facility etc. be done online? This is also more important for you and your future customers because you do not have a branch model. I am sure there must be some way to get it done online. This is just an advice and a request. It will help all and saves everyone's time.
Next when MCX-SX will come, we will have to fill, sign and send papers and forms to you again.
