## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The chip-based card of claim 1 further comprising, a third wire that overlaps the second ends and bridges a connection between the second ends, wherein the third wire configured to connect with the second ends to form the circuit when one or more presses is made on the contact point.

### Claim 3

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; and
one or more ground wires associated with second contact points, wherein the second contact points configured to power off the chip when pressed.

### Claim 4

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; and
a slider configured to extend the second end of the second wire over to and connect with the second end of the first wire when the slider is moved on the chip-based card to form the circuit.
