Do these alternatives compare with just how well UWB serves regular, normal daily activity like this? Because to me, what I have is absolutely excellent in use with daily routine.
I have compared them, and because BLE is a narrowband signal, it is highly susceptible to Non-Line-of-Sight (NLOS) conditions compared to UWB.
I also attended a prototype presentation by a large European silicon company. I noticed that even in their demo, BLE did not achieve 30 cm accuracy, but rather hovered around 1 m.
I have only tested PBR and RTT ranging with a simple Kalman Filter, so maybe someone has found a clever combination of these data sources (I hope).

It will allow things like secure entry (walk up to a door and it opens, be near your car and you can open it), finding your devices (lost keys, headphones, remotes, etc.), auto-unlocking for your laptop, and more.

This is a really cool technology that is going to allow essentially indoor GPS. Imagine going to a mall, and you open a map on your phone, and it immediately knows where you are to under 1m error.

A lot of brick and mortar stores are based on the assumption that a lost customer will buy more things, so I don't see this happening.

BT hardware is also rather affordable.

There may be a rare few legitimate uses for improving the accuracy, but it also makes those privacy nightmares worse.

It generated interesting information, but not interesting enough to be profitable.
We weren't the only ones with this capability either, most major retailers had this level of analytics through surveillance footage that previously existed for loss prevention purposes. Then simply link the data to a rewards number or credit card and you got a stable tracking identity.

So preventing theft?
meindnoch•2mo ago
"Theft" is such a value-loaded, moralizing term. It collapses a wide spectrum of socioeconomic realities into a single criminalized label, ignoring the structural inequities that often shape people's choices. When we say "loss prevention", we're deliberately reframing the conversation away from individual blame and toward systems, environments, and institutional responsibility. Loss prevention isn't about vilifying people - it's about acknowledging that harm occurs within a broader context. It centers the idea that organizations can design safer, more equitable spaces that minimize material loss without resorting to punitive narratives rooted in classism, racism, and centuries-old assumptions about who is "dangerous". Calling something "theft" externalizes accountability onto the most vulnerable actors; calling it "loss" recognizes that institutions have agency, too. And preventing that loss focuses on proactive, compassionate strategies rather than reactive punishment.

If you go to an org's website offering these tools (eg, Everseen mentioned above, RetailNext, etc), they don't directly advertise the full breadth of their capabilities until you have them in a room for a sales pitch. They can combine multiple data streams such that an individual can be traced throughout the store via cameras, wifi, and bluetooth, which gives the retailer an opportunity to sell that information. Did a customer pause in front of the corn chips but then decide not to buy? Print them out a Frito-Lay coupon at checkout and see if you can't get them next time, and Frito-Lay will pay you to do that.

Do you know if smaller shops in india/asia also make use of this?

The whole point is that the thing is set up like a very long serpentine track so that you 'see everything' rather than that you can go to the one thing you want and then to the cash register. This is because they - rightly - figure that if they can keep you in the store longer and expose you to more stuff you might buy more.

I did not claim they guide you to the exit. What I said is that you don't get lost if you stay on the path. A scenic route to the exit is still a route to the exit.
Also: if you want to get to an actual exit it is mandatory (at least over here) to have clearly visible, emergency exit signs so people can get out in case of fire.
