Abstract

A dynamic transaction card that is manufactured using conductive plastic jumpers that will dissolve when in contact with a solvent used to tamper with the dynamic transaction card. Internal components of a dynamic transaction card may be manufactured using a synthetic or semi-synthetic organic material, such as, for example, plastics. These materials may be conductive to provide functionality to a dynamic transaction card, such as a connection between an integrated circuit and other card components such that when the materials dissolve, the connections are broken and the dynamic transaction card may be inactive due to the loss of various connections.

First claim

The invention claimed is:

1. A dynamic transaction card comprising:
an outer layer comprising a plastic material;
electrical components;
at least one connector between the electrical components, wherein:
the connector is constructed from a conductive, dissolvable material;
the connector is arranged in a sequence, wherein the dynamic transaction card will look for the sequence to activate the card; and
upon dissolving the outer layer using a solvent, the at least one connector is dissolved to break the connection between the electrical components and the sequence to deactivate the dynamic transaction card.

2. The dynamic transaction card of claim 1 , wherein the electrical components comprise an integrated circuit, power supply, power management component, microprocessor, microcontroller, and/or a EuroPay-MasterCard-Visa (EMV) chip.

3. The dynamic transaction card of claim 2 , wherein the connector connects the integrated circuit to the power supply and/or power management component.

4. The dynamic transaction card of claim 2 , wherein the connector connects the microprocessor and/or microcontroller to the power supply and/or power management component.

5. The dynamic transaction card of claim 1 , wherein the plastic material comprises polyethylene terephthalate, polyethylene, high-density polyethylene, polyvinyl chloride, polyvinylidene chloride, low-density polyethylene, polypropylene, polystyrene, high impact polystyrene, polyamides, acrylonitrile butadiene styrene, polyethylene/acrylonitrile butadiene styrene polycarbonate, and/or polycarbonate/acrylonitrile butadiene styrene.

6. The dynamic transaction card of claim 1 , wherein a mixed polymer is injected into moldings to irreversibly cure the plastic material to create the connector.

7. The dynamic transaction card of claim 6 , wherein the connector is manufactured using reaction injection molding.

8. The dynamic transaction card of claim 6 , wherein reinforcing agents are added to the mixed polymer.

9. The dynamic transaction card of claim 8 , wherein the reinforcing agents comprise fiber and/or mica.

10. The dynamic transaction card of claim 1 , further comprising a backing layer, wherein the backing layer and the outer layer are molded together.

11. The dynamic transaction card of claim 10 , wherein the backing layer comprises a plastic material.

12. The dynamic transaction card of claim 1 , wherein the connector is x-ray transparent.
