PEACPocket: a technological demonstrator for future multimedia smart card

Abstract

This presented work has been conducted in a framework of a project with the objective to associate power microsources into smart cards in order to create novel functionalities. To demonstrate the feasibility of such a new powered microsystem, a demonstrator named PEA Card is under development.It is powered by two rechargeable batteries:• A microbattery on chip for security applications.• A Thin Film Power Battery inside the card packaging to recharge the microbattery and to supply user interfaces.An ASIC, used as substrate for the microbattery, manages the energy of the two power sources. It is designed to have a very low consumption. A processor and a display, powered by the embedded Power Battery, allow the user to access data without external source of energy. An RFID antenna permits a contactless charge of the two batteries.
