What Is The Meaning Of A Cheque? What Is The Meaning Of A Bearer's Cheque?

A cheque is a piece of paper issued by the bank, to an account holder of that bank, to allow the account holder
to pay third parties for accounts bills and payments,to
avoid the neccessity of using cash.
The cheque is drawn on the account holders account and
is paid  by the bank, thereafter, raising a debit on the account
and reducing the balance by that amount.
The bank will, if the funds are not available in the account,
refuse the cheque and stamp refer to bearer on it.
(However an overdraft could have been previously negotiated, which means the account can run in debit up to a limit).
The bearer is the cheque holder. In this case we refer to it as a bounced cheque and it is unpaid.
