Magnetic chip systems are passive in nature. That means they don't need electrical power, and they don't need their own superpowers. They operate on a frequency of 125 KHZ.
A semiconductor chip is a method of miniaturizing a circuit in electronics technology, usually manufactured on the surface of a semiconductor wafer. A semiconductor is a material that conducts electricity between a conductor and an insulator at room temperature
