What does Dematerialisation process mean?

Dematerialization is when a physical certificate of an investor is converted into an equal number of securities in electronic form. The credit will be credited to the investor's account at his depository Participant. To dematerialize certificates you must first open an account at a DP. Next, fill out a Dematerialization Request Form(DRF) available from DP. Then submit the form along with your physical certificates to request dematerialization. Before the certificates are handed to the DP, ensure that they have been marked: Surrendered For Dematerialization' on the front of the certificates.
