There are existing systems that use IR or lasers to track people... but they don't know who you are -- you are just an anonymous dot on an indoor map of a store. If, say, three people hug each other then then separate, they can't differentiate among the 3 different dots.
BLE (Bluetooth Low Energy) devices can be recognized individually if they are advertising their unique ID (UUID). Mainly these are used for beacons placed at fixed locations in a store. An iOS device can act as a mobile beacon if it advertises its unique ID (UUID). This is totally anonymous as the UUID has nothing to do with you or your device. You can generate a UUID in several ways -- go to:
Every time you reload the page it generates a different UUID. There is a very, very low probability that any two UUIDs will be the same.
So, when your iPhone runs an app that advertises a UUID -- it's unique... that's all. Another app, listening for advertisements detects that there's an unique UUID out there -- but doesn't know what it is or who you are -- just that the UUID is different than any other UUID out there. If you choose (via the app running in your iPhone) you can reveal more info about what kind of device you are, etc.
That's low-level BLE beacons.
Apple iBeacons are a much higher and much tighter implementation.
Your iPhone iBeacon app only listens for UUIDs you are [currently] looking for -- say Macy's, Nordstroms, etc. -- while ignoring Wal-Mart, Target. etc.
Your Phone app can, at your option, advertise your UUID (as defined previously) so you can be tracked, anonymously.
But Apple expects you to detect iBeacons at fixed locations in a store you are listening for (interested in) to alert you to things of interest to you. You can opt in for alerts on items of interest to you, ignore the alerts, or just stop listening.
Hopefully you will buy things (still anonymously)... At some point you will check out and pay for your purchases. if you want to remain anonymous pay cash, or via PayPal [or, in the future] the iTunes store... if not, pay by check or credit card.
In any case, you choose if you are tracked or identified.
3) I like Burberry, where they show additional colours of a dress in the mirror when the woman tries it out in the fitting room
