What does that even mean? They're tracking not only the number of people in a location, but where they go ... then sharing that with their customers. From their own website:
Understand your business in the context of others:
1. Who you share customers with.
2. Where else your loyal customers love to go.
3. Where foot traffic in the city is trending.
How is that respecting my privacy?
"The real danger is the gradual erosion of individual
liberties through the automation, integration, and
interconnection of many small, separate record-keeping
systems, each of which alone may seem innocuous, even
benevolent, and wholly justifiable."

In your system, I'm just an anonymous flow of movements. In the shops billing system, I'm just a CC number and a set of purchases. For the billing provider, I'm just a name and address tied to a CC number. And then with a couple of small leaps, suddenly my whole life is compiled on a single page detailing every breath I take.
So tell me again how I can't use this information to identify who a specific individual is.
