What if I get the IPVM lanyard/logo inked on my neck/chest?
Not acceptable. If you look closely at the blue V in the lanyard logo, you might notice that the coloration is actually due to fine German Wiegand filaments embedded in the fabric itself; Kudos for Brian's clever idea of using the 'rabbit-ears' shape of the letter V itself to enhance signal strength.
These allow the wearer's waypoints and associated dwell times to be captured at each visited booth real-time, and then broadcast thruout the expo's LANyard system, providing the staff at the next exhibit with crucial 'prior interest info' which is then used to tailor their pitch to the attendee.
Thus the guy who is coming from 30 minutes at the Dallmeier Den is likely to be treated differently than someone who lingered for hours in the Longsee Lounge. The monetization received from this data is used to defray the cost of the lanyard.
So unless you are willing to submit to a optical neck scan at each exhibit, you may find yourself listening to the same generic pitch given everyone else... ;)
