Abstract
Near field communication (NFC) methods, systems, and devices are disclosed herein. In an example embodiment, the method includes providing a first NFC device including a NFC antenna, and transmitting a radio frequency (RF) signal including a RF carrier signal by way of the NFC antenna. Also, the method includes receiving a first resonant signal after the transmitting has ceased, and processing the first resonant signal to generate a first portion of transformed signal information. Further, the method includes identifying one or both of a first state and a first event based at least in part upon or associated with the first portion of the transformed signal information.
