Kotak Securities was one of the first to introduce broking transactions on mobile phones. It was a slow start, nearly 6 years ago. Today, as smartphones become the new reality and network speeds improve, the mobile segment contributes around 10% to the overall brokerage revenue. Kamlesh Rao, chief executive officer, Kotak Securities, speaks about the need to continuously update digital platforms to suit clients’ needs. At the same time, it is too early, he says, to write off personal interactions with dealers for all clients.
