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, the metal layer having a visual appearance;
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 and a light guide layer for distributing the light emitted by the one or more LEDs, 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;
a plurality of openings extending partially or entirely through the metal layer, wherein the plurality of openings may be partially or entirely filled with filler and wherein light emitted by the one or more LEDs shines into the light guide and is transmitted out through the plurality of openings; and
wherein the filler is non-transparent and non-translucent with an illuminable front face surface.

2. The transaction card of claim 1 , wherein the light transmitted through the plurality of openings creates a visual appearance that is different from the visual appearance of the metal layer.

3. 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.

4. 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.

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 1 , 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 1 , wherein the illumination circuit is configured to have a variable illumination characteristic dependent upon a characteristic of the harvested energy;
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;
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; and
wherein the illumination circuit is configured to illuminate the red LED in response to harvested energy in a first, relatively lower range, to illuminate the green LED in response to harvested energy in a second, relatively higher range, and to illuminate both the red LED and the green LED when the harvested energy in response to harvested energy in a third, intermediate range between the first, relatively lower range and the second, relatively higher range.

9. The transaction card of claim 8 , wherein one or both of the red LED and the green LED are configured to illuminate with variable intensity.

10. 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, the metal layer having a visual appearance;
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 and a light guide layer for distributing the light emitted by the one or more LEDs, 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;
a plurality of openings extending partially or entirely through the metal layer, wherein the plurality of openings may be partially or entirely filled with filler and wherein light emitted by the one or more LEDs shines into the light guide and is transmitted out through the plurality of openings; 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.

11. The transaction card of claim 10 , wherein the at least one discontinuity comprises a first discontinuity extending from the periphery of the card to the opening containing the transponder module and a second discontinuity extending from the periphery of the card to the opening containing the LED module.

12. 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, the metal layer having a visual appearance;
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 response 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 and a light guide layer for distributing the
