A mobile device adapted to provide an indication of the proximate co-presence of a buddy—another user who has agreed to be indicated as nearby—using a short-range (local) transceiver to scan for a low-level identifier associated with a compatible short-range transceiver in a mobile device operated by the buddy. The mobile device provides an indication of proximate co-presence of another only in case of permission.
