Abstract
Various electronic credentials comprising signal activation are disclosed. An electronic credential core comprises a controller configured to maintain an off-state until activated by a received signal during a personalization process. The electronic credential core further comprises an antenna configured to receive a first signal. The energy in the first signal is harvested by a signal interface. The signal interface generates a second signal using the harvested energy of the first signal. The second signal is provided to the controller. The controller transitions to an active state and continuously performs one or more functions until an onboard battery is depleted. By maintaining an off-state until personalization, the electronic credential can be stored without draining power from the battery, extending the shelf life of the electronic credential.
