Generating geofences

摘要

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating geofences. One of the methods includes receiving, at a mobile device, a signal emitted by a merchant device associated with a merchant. If the signal is emitted by a merchant device associated with a merchant and the distance between the mobile device and the merchant device satisfies a threshold, a notification is provided on the mobile device indicating proximity of the merchant associated with the merchant device.

主权项

1. A computer-implemented method comprising:
obtaining location information for a plurality of merchant locations that are within a threshold distance of a location of a mobile device; determining a first merchant location and a second merchant location that are nearest to the location of the mobile device among the plurality of merchant locations;
determining a triggering geofence that encloses a geographic region that includes the first merchant location and the second merchant location; determining a size of the geographic region enclosed by the triggering geofence;
determining that the size of the geographic region enclosed by the triggering geofence is smaller than a threshold size; based at least in part on the determining that the size of the geographic region enclosed by the triggering geofence is smaller than the threshold size, selecting the first merchant location and the second merchant location to have a common coalesced geofence, wherein the common coalesced geofence is a local geofence shared by the first merchant location and the second merchant location; and associating the first merchant location and the second merchant location with the common coalesced geofence, and wherein detection of the mobile device within the common coalesced geofence triggers a notification on the mobile device indicating a first proximity of the mobile device to the first merchant location and a second proximity of the mobile device to the second merchant location.
