A memory card and a terminal, where the memory card includes a storage device, a controller, and a memory card interface. The storage device and the controller are disposed inside a card body of the memory card. The memory card interface is disposed on the card body of the memory card. The controller is electrically coupled to the storage device and the memory card interface separately. Because a shape of the memory card is the same as that of a nano subscriber identity module (SIM) card, and a size of the memory card is the same as that of the nano SIM card, a nano SD card is provided.

Systems and methods allow for the integrated circuit cards (ICCs) to removably couple to each other and transmit information to an access device as a single device. One among the two or more ICCs coupled together may read data from the remaining ICCs and provide the data to an access device via contactless communication. The ICC may include a substrate; an integrated circuit embedded in the substrate; input ports exposed on a first surface of the substrate, and output ports exposed on a second surface of the substrate. The input ports and the output ports are electrically coupled to the integrated circuit. The output ports are configured to be removably coupled to the input ports of a second ICC.

The present application discloses a wearable apparatus having an apparatus main body including at least one receptacle for detachably attaching a smartcard. The wearable apparatus is compatible with a plurality of smartcards.

A dynamic transaction card that is manufactured using conductive plastic jumpers that will dissolve when in contact with a solvent used to tamper with the dynamic transaction card. Internal components of a dynamic transaction card may be manufactured using a synthetic or semi-synthetic organic material, such as, for example, plastics. These materials may be conductive to provide functionality to a dynamic transaction card, such as a connection between an integrated circuit and other card components such that when the materials dissolve, the connections are broken and the dynamic transaction card may be inactive due to the loss of various connections.

A memory card and a terminal, where the memory card includes a storage device, a controller, and a memory card interface. The storage device and the controller are disposed inside a card body of the memory card. The memory card interface is disposed on the card body of the memory card. The controller is electrically coupled to the storage device and the memory card interface separately. Because a shape of the memory card is the same as that of a nano subscriber identity module (SIM) card, and a size of the memory card is the same as that of the nano SIM card, a nano SD card is provided.

A chip module having a chip coupled to at least one electrically conductive region including a metal, and a coating of the at least one electrically conductive region with a layer of at least one organic silicon compound and/or a form of carbon in a thickness having an electrical surface contact resistance of not more than 500 mΩ according to ISO 7810 in a measurement in accordance with ISO 10373-1.

A “core” or “inlay” for a smartcard may comprise a first metal layer and a second metal layer, and may be formed by folding a single metal layer upon itself. A module cavity may be formed in the first metal layer by laser cutting, prior to laminating. An adhesive layer may be disposed between the two metal layers. A module opening may be formed in the second metal layer by milling, after laminating the first metal layer to the second metal layer. A slit in a metal layer may extend from an outer edge of the layer to the cavity or opening, thereby forming a coupling frame. The slit may have a termination hole at either end or at both ends of the slit. The slits of two metal layers may be positioned differently than one another.

Provided are transaction cards with a reduced weight core. In some approaches, a transaction card may include a body having a first outer layer opposite a second outer layer, and a corrugated core between the first outer layer and the second outer layer, wherein the corrugated core comprises a plurality of alternating peaks and valleys coupled to the first outer layer and the second outer layer. The transaction card may further include an identification chip positioned through the first outer layer, wherein the identification chip is directly coupled to the corrugated core.

Provided are transaction cards including an expanded identification ship. In some approaches, a transaction card may include a body having a first main side opposite a second main side, wherein the body defines an outer perimeter including a first end perimeter opposite a second end perimeter, and a first side perimeter opposite a second side perimeter. The transaction card may further include an identification chip having a plurality of contacts, wherein a first contact of the plurality of contacts extends to at least one of the following: the first end perimeter, the second end perimeter, the first side perimeter, and the second side perimeter.

A metal smartcard (SC) having a transponder chip module (TCM) with a module antenna (MA), and a card body (CB) comprising two discontinuous metal layers (ML), each layer having a slit (S) overlapping the module antenna, the slits being oriented differently than one another. One metal layer can be a front card body (FCB, CF1), and the other layer may be a rear card body (RCB, CF2) having a magnetic stripe (MS) and a signature panel (SP). The slits in the metal layers may have non-linear shapes.
