The disclosed embodiments generally relate to transaction card constructions, and particularly, to a two-piece transaction card construction. Disclosed embodiments include a generally planar first card component including a first surface and a generally planar second card component including a second surface wherein the first card component is separate from the second card component. In disclosed embodiments, for example, the generally planar first card component and the generally planar second card component may be configured such that one forms a cavity and the other forms an inlay component configured to be seated within the cavity. In other embodiments the generally planar first card component and the generally planar second card component may be configured such that one forms a container and the other forms a lid configured to close the container.

A contactless card divider includes a body having a front side and back side and a width therebetween, and a waveguide disposed between the front and back sides. The waveguide is configured to guide a first electromagnetic wave emitted toward the front side through the width of the body to the back side with a first predetermined delay.

A transaction card may include a body having a first part connectable with a second part, and a magnetic stripe on a first main side of the body. A first section of the magnetic stripe is provided on the first part of the body, and a second section of the magnetic stripe is provided on the second part of the body. The transaction card may further include an engagement member extending from the first part of the body for retention within a slot of the second part of the body, the slot embedded within the body between the first main side and a second main side.

The disclosed embodiments generally relate to transaction card constructions, and particularly, to a two-piece transaction card construction. Disclosed embodiments include a generally planar first card component including a first surface and a generally planar second card component including a second surface wherein the first card component is separate from the second card component. In disclosed embodiments, for example, the generally planar first card component and the generally planar second card component may be configured such that one forms a cavity and the other forms an inlay component configured to be seated within the cavity. In other embodiments the generally planar first card component and the generally planar second card component may be configured such that one forms a container and the other forms a lid configured to close the container.

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.

Provided are approaches for customizing transaction cards using a replaceable insert. In some approaches, the transaction card may include a body comprising a first main side opposite a second main side, a first end opposite a second end, and a first side opposite a second side, wherein a chip is coupled to the first main side of the body. An insert may be positioned within a recess along the first main side, wherein a first magnetic material of the recess and a second magnetic material of the insert are positioned proximate one another to increase retention between the insert and the body.

Provided is a medical device assembly for detection of medical device components and/or mating thereof. The medical device assembly may include a first medical device component having at least one first resonant structure, which may have a first resonant frequency spectrum. A second medical device component may have at least one second resonant structure, which may have a second resonant frequency spectrum different than the first resonant frequency spectrum. Upon mating of the first medical device component to the second medical device component, the first resonant structure(s) and the second resonant structure(s) may combine to have a third resonant frequency spectrum, which may be different than the first resonant frequency spectrum and the second resonant frequency spectrum. A system and method are also disclosed.

An electronic device includes a first accommodation portion to accommodate a first card, a second accommodation portion to accommodate a second card, and a holding member capable of holding the first card and the second card. The first accommodation portion and the second accommodation portion are arranged so that an ejection path of the first card and an ejection path of the second card overlap. The holding member is located in an area where the ejection path of the first card and the ejection path of the second card overlap.
