Yes, definatly.
Nobody is actually smuggling anything, it's mostly just an interactive game between people with the apps, albiet one in fairly bad taste and seemingly designed to get a rise out of people if say security is monitoring signals and catches something about smuggling or bombs that is part of some game, hence my other messages.
It's really no differant in practice than certain DS games which you can leave running idle in your pocket or whatever and can do things if the signal comes into proximity with other people running the same game in that mode. Items can be "gifted" that way or experience points granted per system your game came into contact with etc...
Basically what your doing is looking for someone with an open signal "tagging" them, and then doing the same thing later after a set period of time and the game recognizing that you came into contact with the same person/signal more than once.
