Now that's cool!

If anyone knows or can say: What physical principle(s) is the sensor operating on? There doesn't seem to be much information on that (possibly deliberately).

My guess is that it's counting cellphones (based on some RF signature). It probably fingerprints the phones, too, because they claim they can track people across different businesses.

Here's a video of a recent pitch where we explain the technology: http://www.youtube.com/watch?v=0rVpAKziQJA#t=4198s

We're working on more than just wifi as well.

Risky. MAC address tracking is definitely a legal 'grey area' at the moment. I can imagine mining/fingerprinting in this way could easily become illegal in the not-to-distant future.

In the UK, City of London already banned the wifi-enabled bins that were tracking MAC addresses.

It would be really easy to tie a name to MAC address (from point of purchase with a credit card), then see exactly where that person went via the 'sharing' of data with other retailers. This is certainly something you would expect to need 'opt in' to.

So it only counts people that count ;) Just kidding witchya – best of luck!

This is really clever. So it's like Google Analytics (or any analytics) for your brick and mortar business. This is the kind of stuff I love to read about and see being developed, it makes a refreshing change from yet another javascript framework or social network for your pets.
