Abstract
Official abstract text for this publication.
Payment cards with activated information displays are disclosed. In one embodiment, a payment card may include: a first layer; a second layer comprising an elastic material; an actuator; and an information layer between the first layer and the second layer, comprising: a plurality of information voids; and a microfluidic channel that communicates the plurality of information voids with the actuator. A fluid may be provided in the microfluidic channel such that when the actuator is depressed, fluid flows into the information voids making the information voids visible through the second layer, and when the actuator is released, the fluid flows out of the information voids making the information voids substantially invisible through the second layer.
First claim
Opening claim text (preview).
1 . A payment card, comprising: a first layer; a second layer comprising an elastic material; an actuator; and an information layer between the first layer and the second layer, comprising: a plurality of information voids; and a microfluidic channel that communicates the plurality of information voids with the actuator; wherein a fluid is provided in the microfluidic channel such that when the actuator is depressed, fluid flows into the information voids making the information voids visible through the second layer, and when the actuator is released, the fluid flows out of the information voids making the information voids invisible through the second layer. 2 . The payment card of claim 1 , wherein the actuator is in the first layer. 3 . The payment card of claim 1 , wherein the actuator comprises a reservoir in communication with the microfluidic channel. 4 . The payment card of claim 1 , wherein the fluid comprises a gas. 5 . The payment card of claim 1 , wherein the fluid comprises a liquid. 6 . The payment card of claim 1 , wherein the plurality of information voids have a numeric shape. 7 .- 12 . (canceled) 13 . A method, comprising: providing a payment card with a plurality of information voids below a surface comprising of the payment card; actuating an actuator on the payment card, wherein the actuation causes fluid to travel through a microfluidic channel into the information voids, causing the information voids to expand and be visible through the surface of the payment card; and releasing the actuator, wherein the release causes the fluid to flow out of the information voids, causing the information voids to contract and become invisible through the surface of the payment card. 14 . The method of claim 13 , wherein the surface comprises an elastic material. 15 . The method of claim 14 , wherein the elastic material causes the information voids to contract when the actuator is not actuated. 16 . The method of claim 13 , wherein the fluid comprises a gas. 17 . The method of claim 13 , wherein the fluid comprises a liquid. 18 . The method of claim 13 , wherein the plurality of information voids have a numeric shape.
