Abstract: A system includes a user device having a near field communication (NFC) interface. The system also includes a short-range wireless communication interface configured to communicate with devices in a local physical space. The system also includes one or more processors and a non-transitory computer readable storage medium storing instructions for detecting, via the NFC interface, near field proximity between the user device and a NFC-enabled device, receiving pairing information from the NFC-enabled device via the NFC interface, processing the pairing information to establish communication between the system and a wireless-enabled device located in the local physical space via the short-range wireless communication interface, receiving location information from the wireless-enabled device via the short-range wireless communication interface, and determining a location of the user device in the local physical space, relative to at least one reference point, using the location information.
