Abstract
A sensor card includes a signal card substrate in which are mounted a sensor for sensing an external physical phenonemon and for converting the sensed physical phenomenon into an electric signal. An integrated circuit processes the output of the sensor and stores the sensed value represented thereby in a memory. An output terminal outputs the sensed value stored in the memory of the integrated circuit. The sensor card can be adapted not only to store signal-processed detection values but also to have a function for subjecting these signals to computation or evaluation. The stored data can be read out to an external unit in the form of a signal through a physical contact or magnetically in contactless fashion.
