French shoppers have become the first to experience a new LED lighting system that sends special offers and location data to their smartphones.
The technology was designed by Philips and has been installed at a Carrefour supermarket in Lille.
It transmits codes via light waves, which are undetectable to the eye but can be picked up by a phone camera.
The innovation offers an alternative to Bluetooth-based "beacons", which are being installed by many retailers.
[...]Carrefour is using the location data to trigger aisle-specific special offers. If users open a compatible app and let their smartphone camera look upwards, this can be used to determine their location - accurate to up to 1m - and the direction they are facing.

This sounds like it will be too easy, and too fun to resist 'playing games' with.
I can imagine all sorts of hilarity can be induced. (sending shoppers on wild goose chases, fake treasure hunts, etc.-it boggles the mind!)
Hell, it may even become a 'reality show', or 'go viral' on youtube.
