摘要:
A security document such as a credit card or the like has material adapted to be optically scanned arranged along a line in the document. A modulating structure such as a document paper thickness is disposed within the document so as to be positioned between the line and an optically scanning, light sensing device. Accordingly, light emitting material in the line of the card upon being scanned will have the light thereof modulated so as to produce a reproducible authenticating variable when said line is scanned by the light sensing device.

An identification card having photographically recorded individualizing data is provided. The photographically recorded data are interspersed with a security pattern in transparent ink. This pattern is printed onto the photographic layer before the photographic data are recorded. The photographic recording process is carried out in such a way that there is no darkening under the security pattern. The security pattern, recognizable through the transparent printing ink, is thus also impressed upon the photographically recorded data.

A stacking device for sheet material such as banknotes and receipts has a stacker drum with a suction opening at a predetermined location on the periphery. The suction opening grips the leading edges of the sheets to be stacked at a first tangential position and releases the sheets against a stopper at a second tangential position. The stacker drum has air openings on the periphery behind the suction opening. The air openings discharge pulsating compressed air to separate the portion of the sheets trailing the leading edges from the drum.

An identification card or similar data carrier having an IC module for the processing of electrical signals, whereby the IC module along with its leads and contacts is arranged on a separate carrier element which is embedded in the card. An anchoring element is arranged in the area of the carrier element, which anchoring element extends beyond the edge of the carrier element and is connected with the material of the body of the card. This anchoring element is preferably an integrated component of the carrier element.The anchoring element has high tensile strength relative to the material of the identification card. The connection of the carrier or anchoring element with the material of the identification card can be established by recesses or perforations in the edge of the anchoring element, which are penetrated by the material of the identification card during the laminating process, by appropriate laminating adhesives or by specific designing of the anchoring element.

Security paper with luminescing authenticity characteristics which after excitation with invisible light emit exclusively invisible light of different wavelengths as authenticity signal. The luminophores can be included in the printing ink used or they can be added to the paper material in the manufacture of the paper material. A corresponding test apparatus makes it possible to check the authenticity of the security paper in the presence of customers but unnoticed by them; thereby the invisibility of the test signal and the authenticity signal are taken advantage of and the test device is hidden behind a plate non-transmissive for visible light which however is transmissive for the test signal and for the authenticity signal.
摘要:
A method and a device for determining the weight per unit area and/or the thickness of thin material in sheets, for example banknotes, by aid of ultrasonic waves. The device comprises a single- or multi-channel transmitter-receiver arrangement in which the banknote passing through is exposed to a pulsating sound field. The sound is transmitted to the receiver via the banknote which is set vibrating by the sound. For the evaluation of the receiver signal a time interval dependent on the sound propagation time between the transmitter and the receiver is defined which begins when the primary sound arrives at the receiver and ends before reflected portions of the transmitted sound or portions of sound from adjacent transmitters arrive at the receiver. During the time interval the receiver signal which is free from noise signals is integrated. The integration value is a measurement of the density per unit area of the test material. A special integration method allows for the detection of two or more overlapping banknotes.

The invention relates to a security document, in particular a bank note, identity card or the like, having a security element which is provided with characters, patterns, etc., visually readable at least in transmitted light and which is electrically conductive and bears additional substances for machine testing, and to a method for producing such a security element. The security element preferably consists of a transparent film strip that bears negative writing readily capable of visual checking and is additionally provided with electrically conductive and magnetic substances.

A method for producing a mini chip card out of a standard card having an embedded semiconductor chip uses a punching die with cutting edges defining the outer contour of the mini chip card. The punching die is adjusted relative to the standard card and with respect to contact surfaces of the embedded semiconductor chip so that the edges of the punching die are at a predetermined distance from the contact surfaces. The punching of the standard card is performed in this adjusted position so that the contact surfaces are in a reference position with respect to the outer contour of the mini chip card. The punching forms the mini chip card in the correct position in the standard card. The mini chip card may initially remain connected to the standard card by thin bars between the cards.

The invention relates to a method for incorporating a carrier element or module in a card body. The card body is provided with a recess shaped accordingly for incorporating the carrier element. The carrier element comprises a substrate on which an integrated circuit is disposed. Before the carrier element is incorporated a contact adhesive element is first introduced into the recess by means of a suitable tool. The carrier element can then be connected firmly and permanently with the card body with the aid of the contact adhesive element under the action of pressure.
