Certified cheque

When a certified cheque is drawn, the bank operating the account verifies there are currently sufficient funds in the drawer's account to honour the cheque. Those funds are then set aside in the bank's internal account until the cheque is cashed or returned by the payee. Thus, a certified cheque cannot "bounce", and its liquidity is similar to cash, absent failure of the bank. The bank indicates this fact by making a notation on the face of the cheque (technically called an acceptance).
