A calling method can include determining, with a device, a position of a nearby device in response to detecting a signal transmitted from the nearby device and capturing, with a camera of the device, an image of an area near the device. Responsive to identifying an image of a call candidate appearing within the image of the area, a position of the call candidate can be determined from the image. The position of the call candidate can be correlated with the position of the nearby device based on proximity. Information associated with the call candidate can be retrieved based on the correlating. Based on the information retrieved, a visual identifier token corresponding to the call candidate can be generated. The visual identifier token can be presented on a display of the device and can be used by the user to initiate a call between the device and the nearby device.
