1. A method comprising:

  • sensing, via a lower-power processor of a device that is in a sleep state, an environmental variance indicating proximity with a near-field communication-enabled (NFC-enabled) entity, the lower-power processor not capable of authenticating the NFC-enabled entity;

    activating, responsive to detecting the environmental variance via the lower-power processor, a higher-power processor of the device that is capable of authenticating the NFC-enabled entity, the higher-power processor different than the lower-power processor;

    receiving, via a near-field communication (NFC) interface of the device, authentication information from the NFC-enabled entity; and

    authenticating, via the higher-power processor and based on authentication information, the NFC-enabled entity effective to wake the device from the sleep state.
