A method and system for self-service equipment outputting and collecting money. A money box of self-service equipment is provided with two money box statuses which are a functional status and a collecting status. Under the functional status, the money box implements a money storage function used generally in a common situation. When a collecting box is full or in an abnormal status, some money box is chosen and set to switch from the functional status into the collecting status and to act as a temporary collecting box. So the technical problem that the self-service equipment cannot continuously provide cash services when the collecting box or a box for cash no longer fit for circulation is full is solved, the self-service equipment can continuously provide the cash service, that is, money depositing and withdrawing service, under the condition that the collecting box is full, and the starting-up rate of the self-service equipment is improved.
