An electromagnetic-coupling dual IC card includes an IC module and a plate-like card body. The IC module includes a module substrate having a first surface and a second surface, contact terminals provided on the first surface of the module substrate to be contactable with an external contact-type device, an IC chip having a contact communication function and a contactless communication function and disposed on the second surface, and a first connecting coil provided on the first surface. The plate-like card body includes an antenna sheet embedded therein and has a recess for holding the IC module, the antenna sheet being provided with a coupling coil to be electromagnetically coupled to the first connecting coil, and a main coil connected to the coupling coil to perform contactless communication with an external contactless-type device. The first connecting coil does not overlap with the contact terminals in plan view.

A digital printing press for printing security documents is provided. The digital printing press comprises: a first digital print head, the first digital printhead comprising a first array of print nozzles having a first nozzle diameter; a second digital print head, the second digital print head comprising a second array of print nozzles having a second nozzle diameter different from the first nozzle diameter; optionally, an offset printing unit, the offset printing unit comprising one or more offset printing surfaces, wherein the offset printing unit is adapted to transport a print area of the one or more offset printing surfaces sequentially past each of the first and second digital print heads, and subsequently to transfer print received from the first and second digital print heads to a security document substrate; a transport system adapted to transport a security document substrate along a transport path through the digital printing press, wherein either the transport path takes the security document sequentially past each of the first and second digital print heads in a feed direction, or the transport path takes the security document substrate past the offset printing unit, if provided, in a feed direction; a controller adapted to control both the first and second digital print heads to execute a set of printing instructions so as to print on a security document substrate transported past the first and second digital print heads by the transport system or to print on the print area of the one or more offset printing surfaces transported past the first and second digital print heads by the offset printing unit (and to transfer the print received on the print area of the offset printing to the security document substrate), the set of printing instructions including printing instructions at a first resolution for the first digital print head for printing a first print working and printing instructions at a second resolution different from the first resolution for the second digital print head for printing a second print working; wherein the first digital print head is configured to print at the first resolution and the second digital print head is configured to print at the second resolution, and wherein the first and second digital print heads are configured or controlled by the controller to remain static relative to the transport path or offset printing unit while the first and second digital print heads execute the respective printing instructions.

The manufacturing method of the antenna pattern has: a step of forming a dipole antenna on a front surface of a continuous substrate while conveying the continuous substrate; and a step of forming a sub-element on a back surface of the continuous substrate.

An article is authenticated by providing a magnetic security mark in the form of an optically-passive randomly-generated nanoscale magnetic pattern. The pattern is pre-imaged and this reference image is uploaded to a secure database along with an identifier for the article such as a serial number. A user of the article verifies its authenticity by scanning it magnetically to obtain a scanned image of the magnetic pattern. The serial number is used to retrieve the previously uploaded reference image which is compared to the scanned image. If the images match, the article's authenticity is confirmed. A single article may have multiple magnetic security marks, each unique, placed at predetermined, non-uniform locations. The magnetic patterns are generated using thin film deposition of yttrium iron garnet. In one embodiment the article is a physical key having additional security features, such as mechanical features and a radio-frequency identification chip.

A process includes providing a first layer, which is made of a non-opaque plastic material having an initial thickness, covering an area of the first layer with a patterned plate, pressing the patterned plate against a first surface of the first layer so as to form first and second regions thereon, with the second region being thicker than the first region, and removing the patterned plate from the first surface. The patterned plate comprises a cavity having a size of that corresponds to a window.

Methods and systems disclosed herein may communicate information, such as alerts and notifications, to a cardholder via a color-changing transaction card. In particular, the cardholder may configure one or more thresholds that establish when a transaction card may change colors. For instance, a transaction card may change colors at, or while approaching, a first threshold. The transaction card may change colors at, or while approaching, a second threshold. When the cardholder's balance goes below the thresholds, the transaction card may revert back to the lower threshold color or the original color of the transaction card. Using the techniques described herein a financial institution may convey information to a cardholder in a way that does not require the cardholder to digitally engage with the financial institution.
