  • the coupling loop antenna (CLA) may overlap the windings of the antenna structure (AS).
  • the coupling loop antenna (CLA) may be physically connected across one slit (S) in a coupling frame (CF), across several slits arranged in a coupling frame or between slits in a stack of coupling frames making up a card body.

  • the line 718 indicates the boundary between the non-metallic material 720 and the metallic material 710, and represents a metal edge (ME) of the metallic portion 710 which can function like a slit (S), in that eddy currents will be present from which energy can be harvested by a module antenna (MA) or patch antenna (PA) overlying the metal edge (ME).
  • ME metal edge
  • This disclosure further relates to dual interface metal transaction cards comprising two metal layers with at least one slit in each metal layer separated by an adhesively coated dielectric and laminated to synthetic layers to form a metal face transaction card with the objective that the drop acoustics of the metal transaction card sound like metal and not plastic.
  • Retention of the metal sound requires careful selection of the adhesive system and the dielectric (carrier); the thickness of the adhesive layers and the carrier; the melt temperature of the adhesive; the crosslinking processing stage of the adhesive; the choice of each metal layer and their thickness; the choice and thickness of the synthetic layers and the lamination cycle or cycles and its or their respective lamination parameters (pressure, temperature and dwell time).
  • the choice of the adhesive system and the carrier also impacts the ageing of the milling tools used to reduce an inlay of a given format to individual card bodies, in chamfering the card body edges at an angle, and forming a pocket in each card body for later insertion of a dual interface chip module.
  • the dielectric carrier layer may be constructed from a 25 pm Polyethylene Naphthalate (PEN) film coated on both sides with a 25 pm coating of an epoxy based thermosetting adhesive system.
  • the adhesive system plays an important role in maintaining the drop acoustics of the metal card.
  • a hard setting epoxy on a dielectric carrier layer such as PEN, PET or PC has the advantage that after laminating the metal layers (e.g. 25 -up format) together, the epoxy does not re-melt and become tacky from the heat generation caused by the CNC milling (singulation process) in reducing the 25 -up laminated metal inlay to individual card bodies.
  • the adhesive structure on both sides of the PEN carrier may be delivered after the B-stage process, and the adhesive layers may be reactivated in the lamination press process to achieve a non-reversible C-stage in which the adhesive does not melt, flow or become sticky.
  • thermosetting resin and the choice of dielectric have an impact on the drop acoustics of a metal transaction card and on the life of the milling tools used to produce metal card bodies.
  • the secondary coupling frame may be considered to be an "integrated coupling frame".
  • the transponder chip module may be considered to be a capacitive coupling enhanced (CCE) transponder chip module (TCM) Also shown is that the secondary coupling frame may be electrically connected with an external coupling frame (CF).

  • the metallic portion of the metallic/non- metallic cards described herein may comprise at least 25%, at least 30%, or at least 50%, up to 80% or 90% of the overall surface area of the card, the remaining portion of the surface area comprising the non-metallic portion.
  • the metallic portion has a slit (S; 518, 618, 818, 918) to enable the metallic portion to function as a coupling frame (CF).
  • an interface (718) performs the function of the slit, in that a module antenna (MA) or patch antenna (PA) overlying the slit or interface can harvest energy from eddy currents present at the slit or interface with the card is in an interrogation field (such as from a POS terminal).

Abstract

Carte à puce (SC) comportant un corps de carte métallique (MCB) qui est un cadre de couplage (CF) doté d'une fente (S), et une antenne/structure de boucle de couplage (CLA, CLS) connectée à des points de terminaison (TP) de chaque côté de la fente (S) et couplée à l'antenne de module (MA) d'un module de puce de transpondeur (TCM). Une partie du corps de carte (CB) peut être métallique et une autre partie coplanaire du corps de carte peut être un matériau synthétique qui peut être transparent ou translucide. Des courants peuvent être collectés à partir de l'interface entre les deux parties. Le corps de carte (CB) peut comporter deux couches métalliques de différents matériaux, assemblées de manière adhésive l'une à l'autre à l'aide d'un époxy thermodurcissable qui passe du stade B au stade C pendant la stratification.
