Pressed security trace completion

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.
