Official abstract text for this publication.
A transaction device includes a metal layer with one or more discontinuities in the metal layer. Each discontinuity comprises a gap in the metal layer extending from the front surface to the back surface, including at least one discontinuity that defines a path from the device periphery to the opening. A transponder chip module is disposed in the opening. A booster antenna is in communication with the transponder chip module. The device may include at least one fiber-reinforced epoxy laminate material layer. The transponder chip module and the booster antenna may comprise components in a payment circuit, with the metal layer electrically isolated from the payment circuit. The booster antenna may be formed on or embedded in the fiber-reinforced epoxy laminate material layer. Processes for manufacturing transaction devices including a metal layer with one or more fiber-reinforced epoxy laminate material layers are also disclosed.

What is claimed: 1. A transaction device comprising: a metal layer having a front surface, a back surface, a periphery, an opening in the metal layer, and one or more discontinuities in the metal layer, each discontinuity comprising a gap in the metal layer extending from the front surface to the back surface, including at least one discontinuity that defines a path from the device periphery to the opening; a transponder chip module disposed in the opening in the metal layer; and a booster antenna in communication with the transponder chip module, the transponder chip module and the booster antenna comprising components in a circuit configured for wireless communication with a device reader, wherein the metal layer is neither part of the booster antenna nor a component in the circuit. 2. The device of claim 1 , comprising at least two body discontinuities defining respective paths from the device periphery to the opening, wherein the at least two body discontinuities and the opening collectively bisect the device body into at least two discrete portions. 3. The device of claim 1 , further comprising a non-metal molding material in the one or more discontinuities in the metal layer. 4. The device of claim 3 , wherein the non-metal molding material comprises an adhesive or an epoxy. 5. The device of claim 3 , further comprising a reinforcing layer disposed over the metal layer. 6. The device of claim 5 , wherein the reinforcing layer comprises fiberglass. 7. The device of claim 6 , wherein the reinforcing layer comprises a fiber-reinforced epoxy laminate material. 8. The device of claim 6 , comprising a fiber-reinforced epoxy laminate material layer disposed on at least one of the front surface and the back surface of the metal layer. 9. The device of claim 8 , wherein the metal layer is sandwiched between opposite fiber-reinforced epoxy laminate material layers. 10. The device of claim 9 , further comprising a layer of RF-friendly metal foil layer disposed over one of the fiber-reinforced epoxy laminate material layers. 11. The device of claim 10 , further comprising the booster antenna layer disposed over the other of the fiber-reinforced epoxy laminate material layers or disposed between the metal layer and the other of the fiber-reinforced epoxy laminate material layers. 12. The device of claim 11 , further comprising ink on at least one of the outer surfaces of the device. 13. The device of claim 1 , comprising at least one discontinuity in the metal layer extending from the device periphery to a location other than in the opening. 14. The device of claim 1 , wherein at least two of the plurality of discontinuities in the metal layer intersect with one another. 15. The device of claim 14 , wherein the intersecting discontinuities comprise a first discontinuity defining a path from the device periphery to the opening and a second discontinuity extending from an intersection with the first discontinuity to an endpoint that is neither in the opening nor at the periphery. 16. The device of claim 1 , wherein the booster antenna comprises a booster antenna layer comprising a plurality of metallizations. 17. The device of claim 16 , each of the plurality of metallizations is electrically isolated from the metal layer. 18.
