Metal dual interface card

A dual interface transaction card, the card comprising:

• a metal card body having first and second surfaces;
• a contact-only transaction module secured in the card body, the contact-only transaction module comprising contact pads disposed on the first surface of the card body and comprising a first transaction circuit;
• a contactless transaction module secured in a void in the metal card body, the contactless transaction module comprising a second transaction circuit and an antenna, wherein (i) the first transaction circuit and the second transaction circuit are not physically electrically connected to one another and (ii) the first transaction circuit and the second transaction circuit are not connected to any shared circuit component;
• wherein the void comprises a through-hole in the metal card body that extends from the first to the second surface of the card body.

A process for manufacturing a dual interface transaction card, the process comprising the steps of:

• (a) constructing a metal card body having first and second surfaces;
• (b) securing a contact-only transaction module in the metal card body, the contact-only transaction module having contact pads disposed on the first surface of the card body and comprising a first transaction circuit;
• (c) forming a void in the metal card body, the void comprising a blind pocket open to the second surface of the card body and having a bottom adjacent the first surface of the card body;
• and
• (d) securing a contactless transaction module in the void, the contactless transaction module comprising a second transaction circuit and an antenna, wherein (i) the first transaction circuit and the second transaction circuit are not physically electrically connected to one another and (ii) the first transaction circuit and the second transaction circuit are not connected to any shared circuit component.

A dual interface transaction card, comprising:

• a metal card body having first and second surfaces;
• a first hole in the card body that extends from the first surface to the second surface,
• a second hole comprising a pocket in the card body open to the second surface;
• contact pads aligned with the first surface of the card body, mounted in the first hole, and connected to a transaction circuit, and a contactless transaction portion secured in the second hole and coupled to the transaction circuit, the contactless transaction portion having an outer layer disposed flush with the second surface of the card body;
• wherein the contactless transaction portion further comprises a layer containing an antenna, an RF shielding layer, and an adhesive layer.
