A transaction system where at least one teller machine, operating in an on-line mode and an off-line mode, is connected to a host computer. The teller machine can be set during the off-line mode into either of two key wait states for responding to a key wait request command from the host computer so that when a first key wait code is set, further transmission from the teller machine is prohibited until a predetermined key on the keyboard is activated, but when a second code is set, transmission is continued without the necessity of activating the aforementioned key and the transactional data can be further printed for a subsequent backup check.
