1. Method of making a card-shaped, machine-readable information carrier, comprising a first layer, which is enclosed between two further layers opaque at least to visible light, and upon or in which layer data constituting the information are disposed with a predetermined alignment relative to at least one edge of the information carrier, in which method firstly all the layers are laid one upon another in the intended sequence and are bonded to one another to form an integral semifinished product, and thereafter at least one edge intended for guiding the information carrier in the machine reader is cut, characterized in that the first layer, or a frame into which this layer is so fitted that the data are disposed with a predetermined alignment relative to the inner edges of the frame, is furnished with a first guide means aligned relative to the data or to at least one inner edge of the frame and thereafter the guide edge is cut in a cutting tool, which possesses a second guide means, complementary to the first guide means and provided for positioning the semifinished product. |
