Techniques for associating an electronic identifier of a user equipment (UE) with a user of the UE are described. In embodiments of an apparatus, system, method, and computer program of the present disclosure, a UE may transmit an electronic identifier associated with the UE via peer discovery, for receiving by a second UE. A perceivable cue associated with the electronic identifier may be indicated to a second user. The UE or the user of the UE may indicate the perceivable cue to the second user. Selection of the perceivable cue by the second user may cause the initiation of communications between the UE and the second UE.
