Abstract

A transaction card includes at least one metal layer having one or more apertures therein. A light guide is disposed beneath the metal layer. The light guide has a light output and a light input. The light output is positioned to transmit light through at least the one or more apertures of the metal layer. At least one LED is positioned to transmit light into the light input of the light guide.

First claim

What is claimed:

1. A transaction card having opposite finished surfaces and a periphery, the transaction card comprising:
a metal layer having opposite surfaces and at least two openings, each opening extending through one or both of the opposite finished surfaces, and wherein the metal layer has at least one discontinuity extending from the periphery of the card to at least one of the at least two openings in the metal layer and at least one discontinuity connected to and extending between the at least two openings;
a transponder module disposed in one of the at least two openings in the metal layer, the transponder module comprising a component in a transaction circuit configured to communicate wirelessly with a card reader that is configured to emit radio frequency (RF) waves having energy, the transaction circuit configured to receive an incoming RF signal from the card reader, to respond with an outgoing RF signal, and to power the transaction circuit by harvesting energy from the RF waves;
a light emitting diode (LED) module disposed in another of the at least two openings in the metal layer and having a planar illuminated area visible from a finished surface of the transaction card, the LED module comprising: one or more LEDs configured to emit light, the LED module comprising a component in an illumination circuit configured to harvest energy from the RF waves for powering the one or more LEDs; and
at least one non-metal layer disposed on each of the opposite finished surfaces of the metal layer, wherein the at least one non-metal layer comprises a printed pattern, the printed pattern overlying the illuminated area of the LED module and being visible over an unilluminated area of the LED module.

2. The transaction card of claim 1 , wherein the illumination circuit is configured to illuminate independent of status of a payment transaction performed by the transaction circuit.

3. The transaction card of claim 1 , wherein the illumination circuit and the transaction circuit comprise components in a unified circuit in which the illumination circuit is configured to illuminate in a manner indicative of a status of a payment transaction performed by the transaction circuit.

4. The transaction card of claim 1 , wherein the at least one discontinuity extends from the periphery of the card to the opening containing the transponder module and another of the at least one discontinuity extends from the periphery of the card to the opening containing the LED module.

5. The transaction card of claim 1 , wherein the illumination circuit is configured to have a variable illumination characteristic dependent upon a characteristic of the harvested energy.

6. The transaction card of claim 5 , wherein the illumination circuit comprises at least one LED having a variable intensity, wherein the LED is configured to illuminate with a first, relatively lower intensity in response to harvested energy in a first, relatively lower range and to illuminate with a second, relatively higher intensity in response to harvested energy in a second, relatively higher range.

7. The transaction card of claim 5 , wherein the illumination circuit has at least two LEDs and is configured to illuminate one of the at least two LEDs in response to harvested energy in a first, relatively lower range and to illuminate another of the at least two LEDs in response to harvested energy in a second, relatively higher range.

8. The transaction card of claim 7 , wherein the at least two LEDs are each configured to emit a same wavelength of light.

9. The transaction card of claim 7 , wherein at least one of the at least two LEDs is configured to emit a different wavelength of light than the other of the at least two LEDs.

10. The transaction card of claim 9 , wherein one of the at least two LEDs is configured to generate a wavelength in the green visible spectrum of light and another of the at least two LEDs is configured to generate a wavelength in the red visible spectrum of light.

11. The transaction card of claim 1 , wherein the LED module further comprises a light guide for distributing the light emitted by the one or more LEDs across the illuminated area.

12. The transaction card of claim 1 , wherein the printed pattern has a first section overlying the illuminated area of the LED module and a second section disposed across an interface between a periphery of at least one of the openings in the metal layer and the illuminated area of the LED module, the second section being visible over an unilluminated area of the LED module.

13. A transaction card having opposite finished surfaces and a periphery, the transaction card comprising:
a metal layer having opposite surfaces and at least two openings, each opening extending through one or both of the opposite finished surfaces;
a transponder module disposed in one of the at least two openings in the metal layer, the transponder module comprising a component in a transaction circuit configured to communicate wirelessly with a card reader that is configured to emit radio frequency (RF) waves having energy, the transaction circuit configured to receive an incoming RF signal from the card reader, to respond with an outgoing RF signal, and to power the transaction circuit by harvesting energy from the RF waves;
a light emitting diode (LED) module disposed in another of the at least two openings in the metal layer and having a planar illuminated area visible from a finished surface of the transaction card, the LED module comprising: one or more LEDs configured to emit light, the LED module comprising a component in an illumination circuit configured to harvest energy from the RF waves for powering the one or more LEDs;
at least one non-metal layer disposed on each of the opposite finished surfaces of the metal layer, wherein the at least one non-metal layer comprises a printed pattern, the printed pattern overlying the illuminated area of the LED module and being visible over an unilluminated area of the LED module;
wherein the illumination circuit has at least two LEDs and is configured to illuminate one of the at least two LEDs in response to harvested energy in a first, relatively lower range and to illuminate another of the at least two LEDs in response to harvested energy in a second, relatively higher range;
wherein the illumination circuit is configured to have a variable illumination characteristic dependent upon a characteristic of the harvested energy;
wherein the illumination circuit has at least two LEDs and is configured to illuminate one of the at least two LEDs in response to harvested energy in a first, relatively lower range and to illuminate another of the at least two LEDs in response to harvested energy in a second, relatively higher range; and
wherein the first range and the second range are overlapping, such that the illumination circuit is configured to illuminate both of the at least two LEDs when the harvested energy is in the overlapping range.

14. A transaction card having opposite finished surfaces and a periphery, the transaction card comprising:
a metal layer having opposite surfaces and at least two openings, each opening extending through one or both of the opposite finished surfaces;
a transponder module disposed in one of the at least two openings in the metal layer, the transponder module comprising a component in a transaction circuit configured to communicate wirelessly with a card reader that is configured to emit radio frequency (RF) waves having energy, the transaction circuit configured to receive an incoming RF signal from the card reader, to respond with an outgoing RF signal, and to power the tran
