Very easy to program with a compatible smartphone, optimizes daily pasting them everywhere. Random we can:
In a paste in the car and start the GPS application on contact
By sticking a hand in the room and start the music automatically
In a paste on a laptop and start sharing internet access
In another stick in the car that sends an SMS to his half saying "I arriiiive"
He put a link to its website and stick a little anywhere.
In short, it is easy to use, rather funny, and it saves time (well, not much, but for the price, it quickly pays!)
