Systems and methods for exchanging data between two client devices are disclosed. A method includes, at a computer system, obtaining, from a first client device, a first data acquisition request, wherein the first data acquisition request includes (i) a device identifier identifying a second client device distinct from the first client device, and (ii) a search parameter identifier; and identifying the second client device, from a plurality of client devices, in accordance with the device identifier. In some implementations, a method further includes, issuing a second data acquisition request to the second device, the second data acquisition request including the search parameter identifier; obtaining, from the second client device, a search parameter associated with the search parameter identifier; obtaining one or more search results associated with the search parameter; and providing at least one search result in the one or more search result to the first client device for display to a user of the first client device.
