Abstract:
A first near field communication (NFC) device or a first NFC-enabled device utilizes a feedback based approach to allow for dynamic adjusting of one or more operating characteristics. The feedback based approach can be a direct feedback based approach or an indirect feedback based approach. In the direct feedback based approach, a second NFC device or a second NFC-enabled device can communicate information to the first NFC device or the first NFC-enabled device to cause the first NFC device or the first NFC-enabled device to dynamically adjust the one or more operating characteristics. In the indirect feedback based approach, the first NFC device or the first NFC-enabled device can dynamically adjust the one or more operating characteristics in response to the non-occurrence of an event, such as receiving a response command from the second NFC device or the second NFC-enabled device to provide an example.
