A data carrier with detachable parts, a method of forming a data carrier comprising a primary card body, a data carrier puncher for removing detachable parts of data carriers, and a method of removing a form changing part from a data carrier using a puncher are disclosed. The data carrier with detachable parts comprising: a primary card body having a first size; a form changing part disposed within the primary card body and having a second size, the form changing part connected to the primary card body by at least one fixing portion, and the form changing part configured to be removed from the primary card body by breaking the at least one fixing portion; an integrated circuit component embedded in the form changing part; and at least one notch disposed at a first position on a first end of the primary card body.

A tray is insertable forward in a front-rear direction into a connector main of a card connector. The tray has a first card accommodation portion and a second card accommodation portion. The first card accommodation portion is positioned at a position different from a position of the second card accommodation portion in an up-down direction perpendicular to the front-rear direction. The first card accommodation portion has a first elastic beam portion, a first facing portion and a first bulge. The second card accommodation portion has a second elastic beam portion, a second facing portion, and a second bulge. The first elastic beam portion and the second elastic beam portion are positioned at positions different from each other in the front-rear direction. The first elastic beam portion and the second elastic beam portion are elastically deformable independently of each other.

A tag is provided that includes a battery having a printed anode and cathode. A printed circuit connection layer is formed in one of the anode or the cathode. A printed antenna is formed in one of the anode or the cathode. A low-power transmitter coupled to the circuit connection layer.

Embodiments of the present disclosure are directed towards a memory device removably couplable with a mobile device. In some embodiments, the memory device may include a PCB insertable in the mobile device. The PCB may include a first chip (a micro SD device); a second chip (a SIM card); a first contact electrically coupled with the first chip, to provide a first communication interface between the first chip and the mobile device; and a second contact electrically coupled with the second chip, to provide a second communication interface between the second chip and the mobile device. The first and second communication interfaces may provide for respective communications between the micro SD device and the mobile device, and between the SIM card and the mobile device, at the same time, when the PCB is removably coupled with the mobile device.

A tag is provided that includes a battery having a printed anode and cathode. A printed circuit connection layer is formed in one of the anode or the cathode. A printed antenna is formed in one of the anode or the cathode. A low-power transmitter coupled to the circuit connection layer.

An application processing method and apparatus for an embedded universal integrated circuit card (eUICC) are disclosed. The method includes: activating, by a terminal device, an embedded universal integrated circuit card (eUICC); and selecting, by the terminal device, an Issuer Security Domain Root (ISD-R) application on the eUICC during an initialization process of the eUICC, to maintain a session between the terminal device and the eUICC. The session between the terminal device and the eUICC can be maintained during the initialization process of the eUICC.

An apparatus is disclosed herein. The apparatus includes a first liner, a second liner, one or more fastening components, and one or more prongs. The one or more fastening components couples the first liner to the second liner, defining an opening between. The one or more prongs are positionable between a closed position within the opening and an open position exterior to the opening. The one or more prongs include a payment prong. The payment prong includes a body free, a payment chip receptacle, and a payment chip. The body is free from any personal identification information. The payment chip receptacle is attached to the body. The payment chip is positioned in the payment chip receptacle. The payment chip is removable therefrom.

Memory cards for example having a nano card form factor configured according to different card standards. The nano cards have patterns of pads allowing for vertical and horizontal insertion to a host device card slot, while being backward compatible with legacy host device card slots.

A carrier (CA) for multiple chip cards (C1, C2), in particular for multiple subscriber identity modules, SIMs, comprising: a first receptacle (R1) for receiving a first chip card (C1), a second receptacle (R2) for receiving a second chip card (C2), wherein the first and the second receptacle (R1, R2) are arranged symmetric to a central point (P).

A microcircuit card including an overall span of contacts including at least individual contact surfaces connected to this microcircuit while defining two parallel columns situated in proximity to two edges of the overall span, in a card body having a format at least equal to the 2FF format, in which there is made a pre-cutout in the 4FF format surrounding the overall span of contacts and a pre-cutout in the 3FF format surrounding the pre-cutout in the 4FF format, these pre-cutouts being such that the individual contact surfaces have, with respect to each of the pre-cutouts, positions and dimensions such that they encompass the theoretical contact zones defined by the standards defining these 4FF, 3FF and 2FF formats, the upper edge of the pre-cutout in the 3FF format being situated at a distance at least equal to 400 micrometers from the upper edge of the pre-cutout in the 4FF format.
