Abstract
Smartcards having (i) a metal card body (MCB) with a slit (S) overlapping a module antenna (MA) of a chip module (TCM) or (ii) multiple metal layers (M, M, M) each having a slit (S, S, S) offset or oriented differently than each other. A front metal layer may be continuous (no slit), and may be shielded from underlying metal layers by a shielding layer (SL). Metal backing inserts (MBI) reinforcing the slit(s) may also have a slit (S) overlapping the module antenna. Diamond like coating filling the slit. Key fobs similarly fabricated. Plastic-Metal-Plastic smart cards and methods of manufacture are disclosed. Such cards may be contactless only, contact only, or may be dual-interface (contact and contactless) cards.
