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 (M1, M2, M3) each having a slit (S1, S2, S3) 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 (S2) 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.
Claims4
A solid metal smart card comprising:
- a metal card body (MCB) having an opening (MO) for receiving a transponder chip module (TCM);
- a slit (S1) extending from an edge of the card body to the opening;
- wherein the card body is thinned in an area including the slit so that a back side of the metal card body is recessed;
- and
- a metal backing insert (MBI) disposed in the recess, spanning the slit and reinforcing the card body at the slit area.
