1. A transaction card having a card periphery defined by first and second parallel short sides and first and second parallel long sides, the short sides relatively shorter than the long sides, the card comprising:
a metal layer having a front surface and a back surface;
an opening in the metal layer sized to accommodate a transponder chip module; and
a plurality of discontinuities in the metal layer, each discontinuity comprising a gap in the metal layer extending from the front surface to the back surface, at least one of the plurality of discontinuities defining a path from an origin at the card periphery and terminating at a terminus in the opening, wherein one of the terminus or the origin are located relatively closer to a line defined by the first long side of the card periphery than the other, wherein the path has a length greater than a shortest distance from the terminus to the side of the card periphery containing the origin,
wherein the short side of the card periphery has a region aligned with the opening, and the origin is located on the card periphery outside the aligned region, and wherein each discontinuity has a length, wherein fewer than all of the plurality of discontinuities extend from the card periphery to the opening.
