Systems and methods to discover and notify devices that come in close proximity with each other

Abstract

An electronic device of a first user is configured to: connect with a second electronic device of a second user of the plurality of electronic devices over a first peer-to-peer wireless network link when the second electronic device is within a communicable range of the first electronic device; receive from the second electronic device, a second unique code generated by the second electronic device, the second unique code including a second unique identifier of the second electronic device; store on the first electronic device: the second unique identifier; information associated with the proximity of the second electronic device; and information associated with the time when the second electronic device is within the communicable range of the first electronic device; and display a notification on the first electronic device when the second unique identifier is downloaded from a web server to the first electronic device.

What is claimed is: 
     
         1 . An electronic device of a first user comprising:
 one or more processors;   a display coupled to the one or more processors; and   one or more computer-readable media storing instructions executable by the one or more processors, wherein the electronic device is a first electronic device of a plurality of electronic devices, and wherein the one or more processors of the first electronic device are configured to:   connect with a second electronic device of a second user of the plurality of electronic devices over a first peer-to-peer wireless network link when the second electronic device is within a communicable range of the first electronic device;   send to the second electronic device over the first peer-to-peer wireless network link, a first unique code generated by the first electronic device, wherein the first unique code includes a first unique identifier of the first electronic device, the first unique identifier being stored on the first electronic device;   receive from the second electronic device, over the first peer-to-peer wireless network link, a second unique code generated by the second electronic device, wherein the second unique code includes a second unique identifier of the second electronic device, the second unique identifier being stored on the second electronic device;   store on the first electronic device:
 the second unique identifier; 
 information associated with the proximity of the second electronic device; and 
 information associated with the time when the second electronic device is within the communicable range of the first electronic device; and 
   display a notification on the first electronic device when the second unique identifier is downloaded from a web server to the first electronic device.
