1. A transaction card comprising:
a microparticle-based medium, comprising:
a first electrode layer;
a second electrode pixel layer comprising:
at least one first plate; and
at least one second plate; and
a plurality of microcapsules disposed between the first electrode layer and the second electrode pixel layer, wherein:
a first microcapsule of the plurality of microcapsules, disposed between the first electrode layer, the at least one first plate, and the at least one second plate, comprises:
a first plurality of microparticles of a first pigment;
a second plurality of microparticles of a second pigment; and
a transparent fluid, wherein the at least one first plate and the at least one second plate are configured to generate a first electrical charge that causes the first microcapsule to display a first color;
a second microcapsule of the plurality of microcapsules, disposed between the first electrode layer, at least one third plate, and at least one fourth plate, comprises:
a third plurality of microparticles of the first pigment;
a fourth plurality of microparticles of the second pigment; and
the transparent fluid, wherein the at least one third plate and the at least one fourth plate are configured to generate a second electrical charge that causes a second microcapsule of the plurality of microcapsules to display a second color different from the first color;
an integrated circuit configured to:
execute signals received from a point-of-sale terminal;
receive, from the point-of-sale terminal and not from a power supply located on the transaction card, voltage to generate the first electrical charge and the second electrical charge; and
receive, from the point-of-sale terminal, an instruction to apply the voltage to generate the first electrical charge to display the first color and the second electrical charge to display the second color, wherein the instruction is based on a determination, by a third party, that a cardholder has exceeded a first threshold.
