Abstract: An apparatus and a method for executing a money deposit transaction. During a money deposit transaction the state of the bank notes to be deposited is ascertained, bank notes being in a good state are made available to the depositor after the completion of the money deposit transaction, while bank notes being in an unsatisfactory state are withheld.

Abstract: The invention relates to a cassette, a control device, an automatic teller and a method for opening and/or closing such a cassette. Since the cassette can be opened and/or closed contactlessly by means of a radio link between the cassette and a control device, it is possible to make the handling of cassettes much simpler and more time-effective.

Abstract: The present invention relates to a method and apparatus for accepting sheet material, in particular papers of value such as bank notes, checks, etc., whereby different groups of sheet material are successively accepted and stored. In a known method and corresponding apparatus for accepting groups of sheet material such as bank notes, the bank notes coming from a deliverer are checked and stored in a storage container in the order of their input. Thus it is not always recognizable without doubt subsequently, e.g. in cases of malfunction, which deliverer certain bank notes come from. The present invention starts out from the consideration that each group of sheet material is assigned at least one separation means and the separation means are stored at least partly together with the associated group of sheet material for separating the associated group of sheet material from other groups of sheet material.
