摘要:
The present invention relates to a method and system for expiring a device after a predetermined time period has elapsed. A device, which contains its own internal time cell, is designed to stop working or self-destruct after a predetermined time period has expired. The device uses its own time cell so that the elapsed time period is not altered through an external time source. After the predetermined time period has elapsed, the device or a component of the device self-destructs when connected to a power source.
