Abstract
Systems, methods, and devices detect radio frequency identification devices. Methods include transmitting a signal from a transmitter of a wireless device compatible with a wireless communications protocol, and receiving, using a receiver of the wireless device, a signal from a radio frequency identification (RFID) device, the signal comprising one or more resonance parameters. Methods also include generating sensing information and an estimated distance value based, at least in part, on the received signal, the sensing information representing a sensed condition at the RFID device, and the estimated distance value representing an estimate of a distance between the wireless device and the RFID device.
