An interesting article about Core Bluetooth Framework in iOS:
Billboards would be able to broadcast coupons to nearby patrons - no cell reception needed.
A jukebox might advertise the song that’s currently playing with a link to purchase
Your car could broadcast its stats so that when you pull into a gas station the service mechanics will know whether you need an oil change.
Your company badge might broadcast your email address so that connecting at business events becomes even easier.
Your TV could broadcast the link to the current TV channel’s website.
Note, that everything is a push and so has got all the security problems. In the same time our SpotEx approach propagates the pull. And it is safety and anonymous.
