Most smart systems are communicating wireless, while non-stationary systems require an integrated power supply. This paper presents a system, which is integrated into a standardized smartcard format and is capable of active wireless transmission and can be used for location detection, ranging, localization or access control. The dimension of an ISO 7816 ID-1 smartcard, which is the most common used smartcard, is about 86 by 54 mm. Integrating a smart system on this dimensions is not an problem. But the maximal height of a smartcard is only 0.76 millimeters. So integrating functionality by using multiple components is still an issue.en621621004conference paper
