Abstract
Near field detection using a magnetometer is disclosed. A transmitter may distort magnetometer measurements of Earth's magnetic field by producing rapid but controlled fluctuations to encode a specific message in a manipulated magnetic field. When a mobile device is brought in range of the transmitter, a magnetometer of the mobile device detects that manipulated magnetic field. An application running on the mobile device forms messages based on the magnetometer output. In response to detecting the specific message, the application may execute an action on the mobile device or a remote device. NFC read-based near field detection similarly involves the application accessing an NFC chip of the mobile device, and scanning for one or more particular NFC tags that are read by the NFC chip. In response to detecting a particular NFC tag, the application executes an action on the mobile device or a remote device.
