Enhanced performance and security RFID device

An enhanced RFID device embodied in one of inlay, tag, label, sticker or ticket, for securely storing data that is only accessible by at least one compatible reading apparatus when the enhanced RFID device is in an ON mode, and for otherwise preventing access to the stored data, comprising:

• an electronic component operable to store the data;
• an antenna is connected to the said electronic component in the antenna-side (A-side) of substrate;
• at least one enhanced component in at least one enhanced-side (E-side) of substrate, said enhanced component before operated to shield and/or close said antenna, enables increased and/or enhanced electromagnetic induction and/or coupling effect to said antenna, which is said enhanced component enhanced said antenna's performance, to increase readable distances for said antenna and/or said RFID device;
• at least one fold line between the said A-side and said at least one E-side of the substrate;
• wherein said antenna and said at least one enhanced component are formed by conductive material, on at least one layer of substrate, juxtaposed adjacent to each other not electrically connected, wherein said A-side and said at least one E-side is being formed at least one folding angle to said at least one fold line, to enable users to change readability of distances and switch between ON and OFF mode.
