I had been to Lenscrafters, but, there were no location services (no wifi, gps, or bluetooth) turned on...just my cell phone data. By contextual ads, I mean, "News stream ad/in game ad" -- basically, anything that had been targeted to be sent to my device. I believe I read something about Facebook using DataLogic info (which tries to tie payment instruments to advertising clients), but, apparently the music supplier for LensCrafters also has "Audio Beacon" technology for their clients to use (http://us.moodmedia.com/social-solutions/ http://us.moodmedia.com/social-solutions/), so, it could be one of the two.
