Lawyers Send Mobile Ads To Phones In ER Waiting Rooms
1. Geofencing is not very accurate. The range I’ve seen is ~100 yard accuracy. This is potentially a colossal waste of ad spend for lawyers because they get some people in the waiting room, but they also get every single device in the building, parking, and surrounding area.<p>2. They’re called device ids not phone ids. Proof right there the author didn’t research effectively.<p>3. The doctors/etc who have to abide by hiipa are explicitly requires to have their vendors (ex marketers) follow the same laws as them. This goes for any industry, but is written in the law for health.<p>Geofences are awesome for things like sports arenas, neighborhoods, malls, etc. but ineffective for anything smaller.<p>Edit: For #1 here are two sources. This is coming from a vendor that only sells location data, so their accuracy number of 93 feet is definitely not 100% truthful.<p><a href="https://www.placeiq.com/2016/05/study-smartphone-location-only-accurate-to-within-93-feet/" rel="nofollow">https://www.placeiq.com/2016/05/study-smartphone-location-on...</a><p><a href="https://www.placeiq.com/2016/10/location-data-accuracy-the-fast-factors/" rel="nofollow">https://www.placeiq.com/2016/10/location-data-accuracy-the-f...</a>
