Abstract

A transaction card having a partial glass layer including an interior glass member connected to a non-glass frame. The frame defines opposite planar surfaces, has an outer periphery coextensive with the outer periphery of the card, and has a frame inner periphery spaced radially inward from the frame outer periphery. The frame inner periphery defines an interior area occupied by the glass member. The transaction card further includes at least one additional layer having a periphery coextensive with the periphery of the card, and a payment module configured for contactless operation or dual interface contact/contactless operation.

First claim

What is claimed:

1 . A transaction card, the transaction card having lateral dimensions that define an outer periphery and an area, the transaction card comprising:
a partial glass layer comprising an interior glass member connected to a non-glass frame, the frame defining opposite planar surfaces, a frame outer periphery coextensive with the outer periphery of the card, and a frame inner periphery spaced radially inward from the frame outer periphery, the frame inner periphery defining an interior area occupied by the glass member; at least one additional layer having a periphery coextensive with the periphery of the card, the at least one additional layer comprising a booster antenna layer comprising a booster antenna; a payment module configured for contactless operation or dual interface contact/contactless operation, the payment module being physically or inductively connected to the booster antenna; and a transparent layer forming an outermost surface of the card and disposed above at least the partial glass layer, wherein at least the booster antenna is visible from the outermost surface of the card.

2 . The transaction card of claim 1 , wherein the outer periphery of the transaction card ( 100 ) is defined by a plurality of straight edges and corners (c), wherein the frame ( 206 ) defines a plurality of frame widths between the frame outer periphery (FOP) and the frame inner periphery (FIP) along the respective plurality of straight edges, including a first frame width (FW 1 ) between the frame outer periphery and the frame inner periphery along a first edge that defines a card length, a second frame width (FW 2 ) between the frame outer periphery and the frame inner periphery along a second edge that defines a card width perpendicular to the card length, a third frame width (FW 3 ) between the frame outer periphery and the frame inner periphery along a third edge parallel to and opposite the first edge, and a fourth frame width (FW 4 ) between the frame outer periphery and the frame inner periphery along a fourth edge parallel to and opposite the second edge, wherein at least one of the plurality of frame widths is uniform along an entirety of the respective straight edge.

3 . The transaction card of claim 1 , wherein the transparent layer comprises a hard coat layer, polymeric materials, printed information or graphics, or a combination thereof.

4 . The transaction card of claim 1 , wherein the glass member comprises conformable glass.

5 . The transaction card of claim 1 , wherein the at least one additional layer comprises a pair of opposite capping layers, wherein the partial glass layer is disposed between the pair of opposite capping layers.

6 . The transaction card of claim 1 , wherein the glass member has a first thickness and the frame has a second thickness greater than the first thickness.

7 . The transaction card of claim 6 , further comprising a layer of adhesive in a region bordered by the glass member, the frame, and the at least one additional layer of the transaction card.

8 . The transaction card of claim 1 , wherein the at least one additional layer further comprises at least a non-metal base layer and one or more printed layers.

9 . The transaction card of claim 1 , further comprising a non-RF-impeding layer between the booster antenna and the metal frame.

10 . The transaction card of claim 1 , wherein the glass member has a first thickness and the frame has a second thickness greater than the first thickness, wherein the partial glass layer constitutes an outermost layer of the transaction card, and the frame defines a greater elevation on the surface of the card relative to the at least one additional layer than an elevation defined by the glass member.

11 . The transaction card of claim 1 , wherein the frame comprises a non-metal material.

12 . The transaction card of claim 11 , wherein the frame comprises at least one groove, and the booster antenna comprises a winding disposed within the at least one groove.

13 . The transaction card of claim 11 , wherein the frame defines an outer peripheral edge, a top surface, and a bottom surface, and the at least one groove is disposed on the top surface, the bottom surface, or a combination thereof, and radially inset from the outer peripheral edge.

14 . The transaction card of claim 13 , further comprising a filler disposed over the booster antenna in the groove.

15 . The transaction card of claim 1 , wherein the inner periphery of the frame defines a non-stepped edge between the top planar surface and the bottom planar surface of the frame.

16 . The transaction card of claim 15 , wherein the non-stepped edge comprises a straight edge perpendicular to the top planar surface and the bottom planar surface.

17 . The transaction card of claim 1 , wherein the inner periphery of the frame defines a stepped edge between the top planar surface and the bottom planar surface of the frame, the stepped edge defining a ledge intermediate the top planar surface and the bottom planar surface of the frame, wherein a surface of the glass member is supported by the ledge.

18 . The transaction card of claim 17 , wherein the glass member defines a non-stepped outer peripheral edge aligned with and adhesively connected to the non-stepped edge defined by the inner periphery of the frame.

19 . The transaction card of claim 17 , wherein the ledge defines a planar surface parallel to the top planar surface and the bottom planar surface of the frame.

20 . The transaction card of claim 19 , wherein the glass member has a first thickness and the frame has a second thickness greater than the first thickness.

21 . The transaction card of claim 20 , wherein the ledge has a thickness equal to a difference between the first thickness and the second thickness.

22 . The transaction card of claim 17 , wherein the ledge defined by the frame is disposed between the glass member and the at least one additional layer having the periphery coextensive with the periphery of the card.

23 . The transaction card of claim 22 , further comprising an intermediate layer having a periphery defined by an inner periphery of the ledge disposed between the glass member and the at least one additional layer having the periphery coextensive with the periphery of the card.

24 . The transaction card of claim 17 , wherein the intermediate layer comprises an adhesive layer, a transparent layer, glass, or a combination thereof.

25 . The transaction card of claim 17 , wherein the glass member is disposed between the at least one additional layer and the ledge defined by the frame.

26 . The transaction card of claim 25 , wherein the partial glass layer constitutes an outermost layer of the transaction card.

27 . The transaction card of claim 25 , wherein the partial glass layer has an outer protective layer adhered thereto that constitutes an outermost layer of the transaction card.

28 . The transaction card of claim 25 , wherein the frame consists of a metal material.

29 . The transaction card of claim 1 , further comprising at least one protective layer over the partial glass layer.

30 . The transaction card of claim 1 , wherein at least one of the plurality of frame widths is uniform along an entirety of the respective straight edge except in at least one t
