Patent ID: 10318860

Abstract:
Techniques are described for powering a chip-enabled card using a wearable computing device. The chip-enabled card is paired with the wearable computing device and a specific signal is generated for the chip-enabled card. When the chip-enabled card is proximate to the wearable computing device, the wearable computing device transmits the specific signal associated with the chip-enabled card through a conducting element in contact with the user's body, through the user's body, and to a touch pad of the chip-enabled card that is also in contact with a portion of the user's body. According to the disclosed techniques, the chip of the chip-enabled card verifies that the received specific signal is associated with the chip-enabled card, and uses the verified specific signal to power subsequent transactions performed by the chip-enabled card. In this way, the chip-enabled card only emits a signal to perform transactions when the user is holding the card.
