Abstract
A hardware device known as a RICH coupler which works between an IC card and its corresponding terminal system. The function of the RICH coupler depends upon its position. Between the card level and the system level there is a third independent level, the coupler. The card level and the system level are involved in the specific card application. The coupler level is application independent. The present invention provides an application independent RICH coupler which works like a supervisor between the applications on the card level and the applications on the system level.
