Screen Printed Security-Button for Radio Frequency Identification Tags

Abstract

Radio frequency identi cation (RFID) security is a relevant matter. The wide spread of RFID \napplications in the general society and the persistent attempts to safeguard it con rm it, especially since its \nuse involves payments and the store or transmission of sensitive information. In this contribution, we present \nan innovative solution for improving the security of RFID passive tags through the use of a screen printed \nbutton, that allows the reception and transmission only when a certain level of physical pressure normal to \nits plane is applied. The materials and fabrication technology used demonstrate an easy to implement and \ncost-effective system, valuable in several scenarios where the user has straight contact with the tags and \nwhere its usage is direct and intentional.
