Abstract
Each document (W1) is provided with a security feature in the form of a foil component (2) which is permanently attached to the document and cannot be changed without destroying it. Before the foil components are applied to the documents, they are provided with machine-readable image information which is variable from one foil component to another (3a, 4a). Once the foil component has been applied, the documents are passed through a reading device which reads the variable image information (3a, 4a) and controls a printer which applies a copy of this variable image information to the document outside the foil component. This can be in particular a combination of characters (7a) which is printed as part of a serial number (6a).
