what is a transaction account and why is it a demand deposit
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.
