A method, an apparatus and a system relate to processing a transport container for objects of value, particularly value documents, such as for example banknotes. The method comprises the steps of feeding the transport container to an apparatus for processing the transport container, opening the transport container in the apparatus, emptying the objects of value from the transport container, and checking the transport container for a residual quantity. For the check, electromagnetic radiation is applied to the transport container, wherein a transmission image of the transport container is produced by means of the electromagnetic radiation. The residual quantity in the transport container is deduced by means of the analysis of the transmission image.
