Abstract
A micropowered module containing an integrated circuit packaged with a battery. The module is originally in a state of zero power consumption. When the module is to be put into use, a very strong electromagnetic field is applied at a predetermined frequency. A preset pulse code at this frequency will activate logic elements to keep the integrated circuit turned on, in active or standby mode. In standby mode, the power from the battery will avoid data loss.
