ABSTRACT:
A computer program product has a check routine and an active part. When the computer program product is called, a computer, while processing the check routine, initiates a transmitter to send a launch signal. A transponder receives this signal, checks whether a time-dependent and/or usage-dependent transmission condition is met and transmits an enable code as warranted. A receiver receives the enable code and communicates it to the computer. The computer checks the enable code and undertakes processing of the active part only when the enable code satisfies an enable condition.
