demat

A demat account is an Indian term for a dematerialized account that holds financial securities (equity or debt) digitally for traded shares in the share market. In India, demat accounts are maintained by two depository organizations: the National Securities Depository Limited and the Central Depository Services Limited.
A depository participant (DP), such as a bank, acts as an intermediary between the investor and the depository. In India, a DP is described as an agent of the depository. The relationship between the DPs and the depository is governed by an agreement made between the two under the Depositories Act. The demat account number is quoted for all transactions to enable electronic settlements of trades to take place. Access to the dematerialized account requires an internet password and a transaction password which allows the transfers or purchases of securities.
A security is a tradable financial asset; the term commonly refers to any form of a financial instrument, but its legal definition varies by jurisdiction. Purchases and sales of securities on the demat account are automatically made once transactions are confirmed and completed.
