CAPACITIVE EMBEDDED DUAL INTERFACE METAL CARD

Abstract

A transaction card having a metal layer, an aperture in the metal layer for a transponder chip, and at least one discontinuity extending from a starting point on the periphery of the card to an ending point in the aperture. The card has greater resistance to bending than a card having a comparative discontinuity with the ending point and the starting point at the same distance from a line defined by a first long side of the periphery of the card in the absence of one or more reinforcing features.The reinforcing features include a discontinuity where one of the termination point or the start point is relatively closer to the first long side of the card periphery than the other, a plurality of discontinuities where fewer than all extend from the card periphery to the aperture, a self-supporting, non-metallic layer disposed on at least one surface of the card, or one or more ceramic reinforcing protrusions surrounding the aperture.
