Interoperable device location

Abstract

A method of locating interoperable devices at a location, comprising receiving from a guest device at the location a query over a network to a location server. The query includes an indicator of location of the guest device, and an identifier of the guest device. The method includes querying a data store, to identify a set of proximate interoperable devices at the location, using the indicator of location; identifying permitted proximate interoperable devices from the set of proximate interoperable devices, for which contact permission by the guest device has been granted; and dispatching a message over the network to each of the permitted proximate interoperable device causing them to emit a beacon signal, that is audible or visible at the location.
