When forming layer stacks in the presence of solder material, uncontrolled flow of the solder material at the interface of two different layers of the layer stack may significantly be mitigated by providing an area of increased pressure in the material of the overlaying foil layer. For example, the area of increased pressure may be generated during the lamination process by providing a pressure inducing structure, for instance on the underlying foil layer, which laterally surrounds the solder material and therefore, in combination with the material of the overlying foil layer, reliably confines the solder material.

Systems and methods for using, configuring, and manufacturing self-obscuring tamper-evident labels can include producing labels that have adhesive and non-adhesive sides. The non-adhesive side can be configured to receive printing such as machine-readable codes. The labels typically have multiple layers which can be configured for various tasks. For example, one layer can be configured as an irreversible void material that generates indicia upon receiving a certain tension associated with removal from a surface. Another layer may be configured to ease the removal of the label from a surface while another generates deformations under tension. The indicia, deformations, and machine-readable code printed on the non-adhesive side can be configured such that when activated, the indicia render the machine-readable code unreadable via machine. These labels can be utilized as security labels designed to indicate prior removal as well as other applications that can benefit from quick removal and prior removal indication.

A manufacturing method of a smart card. The manufacturing method comprises: respectively hollowing out a plurality of substrates to obtain a plurality of hollowed-out substrates (101); synthesizing the plurality of hollowed-out substrates to obtain a multilayer synthesized hollowed-out substrate (102); filling the synthesized hollowed-out substrate with an internal insert (103); and coating the synthesized hollowed-out substrate with adhesive to obtain the smart card (104). By adopting the technical solution that a multilayer synthesized hollowed-out substrate is obtained by synthesizing a plurality of hollowed-out substrates, and the synthesized hollowed-out substrate is filled with an internal insert, the production difficulty of the smart card with a function of human-computer interaction is reduced, and the production efficiency is increased.

A thermoplastic resin sheet having hair-like bodies expressing good tactile sensation and surface quality, and a molded article thereof. The thermoplastic resin sheet is arranged regularly on at least one surface of a base layer, a continuous phase being formed without a structural boundary between the base layer and the hair-like bodies, wherein the hair-like bodies have an average height of 30 μm or more and 500 μm or less, the surface having the hair-like bodies has an L* value of 20 or less in an L*a*b* color system based on color difference measurement (JIS Z 8729), and the surface having the hairlike bodies has a 60-degree specular gloss (JIS Z 8741) of 1.5% or less.

Security article and method for producing a security article. The method includes microprinting on a patch an array of microimages, placing a first translucent layer over the substrate and first patch, and laminating the substrate, the patch, and the first translucent layer using a lamination tool. The resulting security product includes a microlens array is located in the first translucent layer in register with the patch such that microimages have a one-to-one correspondence with lenses of the array of microlenses, wherein when the microimage array is viewed by a viewer through the microlens array, a composite image is visible to a viewer of the security article.

A transaction card includes at least one metal layer having one or more apertures therein. A light guide is disposed beneath the metal layer. The light guide has a light output and a light input. The light output is positioned to transmit light through at least the one or more apertures of the metal layer. At least one LED is positioned to transmit light into the light guide light input.

Connection bridges (CBR) for dual-interface transponder chip modules (TCM) 200 may have an area which is substantially equal to or greater than an area of a contact pad (CP) of a contact pad array (CPA). A given connection bridge may be L-shaped and may comprise (i) a first portion disposed external to the contact pad array and extending parallel to the insertion direction, and (ii) a second portion extending from an end of the first portion perpendicular to the insertion direction to within the contact pad array (CPA) such as between C1 and C5. The connection bridge may extend around a corner of the contact pad array, may be large enough to accommodate wire bonding, and may be integral with a coupling frame (CF) extending around the contact pad array. The transponder chip modules may be integrated into a smart card (SC).

A transaction card that includes a card body that can include a ceramic material. The card body can include a primary surface and a secondary surface, a laser marked feature disposed on the card body and a laser etched feature disposed on the card body. A method of making a transaction card can include forming a ceramic material slurry comprising a ceramic material and a binder, forming a green body from the ceramic material slurry, firing the green body at a firing temperature to create a fired ceramic body, grinding the fired ceramic body into a card body, and polishing a primary surface of the card body.

A method of processing sheet stock in the creation of plastic cards, such as gift cards or credit cards that include special effects and/or security measures. A card formed by such methods is also disclosed. The method provides for two or more dissimilar materials to be bonded together while maintaining the integrity of the card and as any graphics, security features, and/or special effects provided thereon. Thermoset and thermobond adhesive layers are placed between a first material layer and a second material layer of the sheet stock. The thermoset and thermobond adhesive layers allow the first and second material layers to move independently and to expand and contract at different rates relative to each other. The adhesive layers enable the sheet stock to be rolled up for shipping or storage and further enable the end product produced therefrom to have a planar profile.

A security device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. At least one first or second segment can include one or more microstructures or one or more nanostructures configured to produce one or more colors for the first or second image.
