1. A biometric smart card, comprising:
a first polymer layer;
an electrical substrate layer having at least one interconnect layer over the first polymer layer;
an antenna proximate to the electrical substrate layer;
a metal layer proximate to the antenna and the electrical substrate layer, the metal layer comprising a plurality of circumferential apertures extending from a periphery of the smart card toward an interior central portion of the smart card; and
a second polymer layer over the metal layer, wherein the plurality of circumferential apertures in the metal layer allow the smart card to flex in one, two or three dimensions.
