This study aims at the development of an electrochromic display on paper, activated by a smartphone as solution for counterfeit. A novel deposition method at room temperature of WO3 thin films was developed using a UV treatment. 5-layer electrochromic device (ECD), based on WO3 on paper, Prussian blue, and an electrolyte membrane, showed good electrochemical stability for more than 500 cycles associated with an optical contrast in reflectance ΔR of 13% at -1 V. In order to minimize the activation potential, ECDs with simplified architecture, derived from 5-layer conventional configuration have been developed in a second part of this work. 4-layer ECDs were constructed by replacing the counter-electrode and conductive layer by a single metal...
