METHODS OF USING NAIL ENHANCEMENT SYSTEMS AND AN ASSOCIATED MOBILE APPLICATION

原文（中国語）

A nail enhancement includes a conductive substrate configured for placement proximal to a nail of a wearer and a color-changing layer comprising a chromic material that is integrated with the conductive substrate. A method of customizing the appearance of a fingernail or toenail includes providing the nail enhancement, adhering the conductive substrate to the fingernail or the toenail, and activating the color-changing layer by providing electrical current or heat to the color-changing layer. The nail enhancement may also be used in methods of exchanging information, including methods of making payments using the nail enhancement.
