Abstract
A structure for a contact-less card, the contact-less card may include a touch sensor electrically coupled to a fixed power source or electrically coupled to an antenna. The contact-less card may include a contact-less communication controller electrically coupled to the touch sensor. The contact-less communication controller includes an integrated circuit containing card information. The integrated circuit transmits the card information based on a signal from the touch sensor. The contact-less card may include an antenna electrically coupled to the contact-less communication controller. The antenna transmits card information received from the contact-less communication controller.

A contact-less card, the contact-less card comprising:
- a touch sensor electrically coupled to a fixed power source;
- a contact-less communication controller electrically coupled to the touch sensor, wherein the contact-less communication controller comprises an integrated circuit containing card information, and wherein the integrated circuit transmits the card information based on a signal from the touch sensor and based on a change occurring in an electric state of current passing between the touch sensor and a touch relay;
- and
- an antenna electrically coupled to the contact-less communication controller, wherein the antenna transmits card information received from the contact-less communication controller.
