Abstract: A transaction card having a metal layer, an opening in the metal layer for a transponder chip, and at least one discontinuity extending from an origin on the card periphery to a terminus in the opening. The card has a greater flex resistance than a card having a comparative discontinuity with the terminus and the origin the same distance from a line defined by a first long side of the card periphery in an absence of one or more strengthening features. Strengthening features include a discontinuity wherein one of the terminus or the origin are located relatively closer to the first long side of the card periphery than the other, a plurality of discontinuities wherein fewer than all extend from the card periphery to the opening, a self-supporting, non-metal layer disposed on at least one surface of the card, or one or more ceramic reinforcing tabs surrounding the opening.

Abstract: A process for making a transaction card defined by a plurality of layers is described. The process includes providing a first portion of the card, the first portion comprising a non-plastic layer having first and second faces and a thickness therebetween; forming an opening in the non-plastic layer, the opening defined through the first face; disposing embedded electronics in the opening; providing a second portion of the card; and providing a fill disposed in portions of the opening not occupied by the embedded electronics and attaching the first portion of the card to the second portion of the card.

Abstract: A transaction card comprising a metal layer. A first cut out region in a first surface of said metal layer has a depth less than the thickness of the metal layer, and a first portion of an integrated circuit (IC) module is secured therein. A second cut out region extends from the first cut out region to the second surface of said metal layer and defines a non-RF-impeding volume having a perimeter greater than the perimeter of the first cut out region. One or more additional layers are stacked on the second surface of the metal layer, and a channel extends between one of the stacked layers and the IC module.
