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, receiving, using a receiver of the wireless device, an encoded signal from a radio frequency identification (RFID) device, and determining a plurality of data values based, at least in part, on the received encoded signal. Methods further include generating an estimated distance value based, at least in part, on the received encoded signal, the estimated distance value representing an estimate of a distance between the wireless device and the RFID device.
