A phased array can still provide positioning reports even if it can't decipher the data. And, well, doing so would be illegal. Frankly, I'd use facial recognition combined with a phased array to realtime plot people in a facility. And if they use their credit card, I'd then connect the CC, their face, the pattern they walked, and to the free wifi the store provides to get access to phone-OS data. Now you can realtime track all your customers who show up. And that data gets sold to whoever buys. Hmm, buying unhealthy food from your receipt? Your insurance company bought the list and will now raise rates on you.
