A transaction card can be manufactured from rigid materials, such as glass, stone, or ceramics. The transaction card can have a first rigid layer having a first external surface and a first internal surface, with a pocket within the first external surface of the first rigid layer. The transaction card can have a second rigid layer having a second external surface and a second internal surface. A binding layer can be located between the first rigid layer and the second rigid layer can affix the first rigid layer to the second internal layer. An integrated circuit chip can be affixed within the pocket of the first rigid layer. A rim can extend from the first external surface of first rigid layer around a first edge of the first rigid layer and a second edge of the second rigid layer and onto the second external surface of the second rigid layer.

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.

A device for contactless communication with a terminal, the device comprising: an antenna for receiving a wireless signal emitted by the terminal; an embedded chip configured to generate data for communication to the terminal to perform a first function associated with the device; and a module separate from the chip configured to perform processes as part of a second function associated with the device, the module being connected to the antenna and comprising a power-harvesting unit configured to harvest power from the received wireless signal to power at least the module.

The present invention relates to card-type information substrates, such as payment cards, in which a frame is implemented so as to impart increased weight and/or superior appearance to the card-type substrates, wherein the influence of the frame on the RF performance of the card-type substrate is taken into consideration. For example, in illustrative embodiments the influence of a conductive material in the frame is reduced by selecting one or more appropriate features countering the negative effect on the RF performance.

The invention relates to a method for producing a module having an electronic chip including metallisations which are accessible from a first side of the metallisations and an integrated circuit chip which is arranged on the second side of the metallisations, opposite the first side. The method comprises the step of forming electrical interconnection elements which are separate from the metallisations, directly connecting the chip, and are arranged on the second side of the metallisations. The invention also relates to a module corresponding to the method and to a device comprising said module.

Method for the electrochemical metallization of a double-sided electrical circuit for a chip card. Contacts and current leads are located on a front face. An antenna and connection pads are located on a rear face. This method includes an operation of electrochemically depositing at least one layer of electrically conductive material on connection pads, while supplying these connection pads with current via the current leads, contacts and metallized holes establishing electrical continuity between the front face and the rear face. This method furthermore includes, after the operation of electrochemically depositing at least one layer of electrically conductive material, an operation of electrically isolating at least one metallized hole from a connection pad. Electrical circuit obtained using this method.

A computerized transaction card is provided and includes a plastic form factor resembling a credit card, the form factor including all or a combination of a magnetic stripe, a euro-pay master card and visa (EMV) chip, and or a near field communication (NFC) chip, a micro-controller powered by a rechargeable battery, at least one wireless chip set for sending and receiving data over a local wireless network; and, an interactive display screen for displaying information to a card operator.

A method can include obtaining contact data corresponding to a set of contacts of an authorization card. The contact data can indicate a set of engaged contacts among the set of contacts. The method can include obtaining activation data corresponding to a set of predetermined engaged contacts among the set of contacts. The method can include determining, by comparing the contact data to the activation data, that the set of engaged contacts matches the set of predetermined engaged contacts. The method can include changing, in response to the determining, a state of the authorization card from an inactive state to an active state. The method can include permitting, in response to the changing the state, an electronic transfer of authorization data from the authorization card.
