what is a transaction account and why is it a demand deposit
Transaction account A transaction account, checking account, current account or demand deposit account is a deposit account held at a bank or other financial institution. It is available to the account owner "on demand" and is available for frequent and immediate access by the account owner or to others as the account owner may direct. Access may be in a variety of ways, such as cash withdrawals, use of cheques (checks) and debit by electronic transfer. In economic terms, the funds held in a transaction account are regarded as liquid funds and in accounting terms they are considered as cash.
Demat account All applicants should carry original documents for verification by an authorized official of the depository participant, under his signature. Further, the investor has to sign an agreement with the DP in a depository prescribed standard format, which details rights and duties of investor and DP. DP should provide the investor with a copy of the agreement and schedule of charges for their future reference. The DP will open the account in the system and give an account number, which is also called BOID (Beneficiary Owner Identification number). The DP may revise the charges by giving 30 days notice in advance.
