Abstract
Described herein is a system and method for enabling communication with a user device using that user device's magnetometer. In some embodiments, a magnetic beacon may generate a sequence of input signals that correspond to activations and deactivations of a magnetic field. A magnetometer in a user device may detect sudden changes in magnetic field and may be used to determine that those changes include a message. In some embodiments, the user device may monitor for an initiation sequence. Upon detecting a sequence of magnetic field activations and deactivations (which may appear to the magnetometer as a sequence of sudden rotational position changes), the user device may interpret a message conveyed by the magnetic beacon. In some embodiments, the user device may communicate the message to a service provider computer, which may subsequently identify additional information related to the message and provide that additional information to the user device.
