No. iBeacons broadcast their own presence only and cannot be used for surreptitious user tracking. The only way an iBeacon could be used to track is in concert with an app running on the user's phone that communicates back to the business, letting them know you're near the beacon. In other words the user has to opt in to tracking, which is how it should be.
