Abstract
A contactless card is provided. The card in a non-activated state lacks a circuit between a chip on the card and an antenna on the card. When one or more contact points on the card are pressed, the circuit is formed and the chip is powered on through an antenna that receives signals from a card reader. Once powered on, in an embodiment, the chip produces a one-time transaction specific token for authenticating a transaction using the card.
Claims4
A chip-based card, comprising:
- a chip;
- an antenna;
- a first wire connected to the chip on a first end and disconnected at a second end;
- a second wire connected to the antenna on a first end and disconnected at a second end;
- at least one contact point;
- wherein the second ends are configured to be connected to form a circuit between the chip and the antenna at the at least one contact point;
- an area that separates the second ends, wherein the second ends overlap one another within the area without touching, and wherein the second ends are configured to connect with one another within the area to form the circuit when a press is made on the contact point;
- and
- a non-conductive liquid that fills the area and configured to form a temporary bond that keeps the second ends connected to form the circuit until the temporary bond subsides after the press.
