Hotel towels, to prevent theft.

How do they prevent theft, exactly?

The local Gold's Gym has a theft prevention style detector around the front door which will complain if you try and leave with a towel. The towels themselves have an obvious bump in one corner, about the size of a jellybean.

RFID is one of those things that seem cool until you start playing with it and then it turns out that the only uses for it are really boring. Like, you can't use it to locate stuff because the range is too short; you can't rely on stuff to have chips (food, or clothes or whatever) and it's a major time sink if you'd have to start tagging stuff yourself; it's cumbersome to install readers everywhere and not being able…

Wait, sorry... what?! You had an RFID chip implanted in your hand??? I think that story deserves a little elaboration. EDIT: Wow, this is apparently a thing. [0] [0] https://en.wikipedia.org/wiki/Microchip_implant_(human)#Hobb...

Not much to it, really. It became feasible around 2007-2008 ish or so, when you could buy glass ampules with rfid tags in them and simple readers retail online (my timing might be a few years off). There were several forums about it at the time, most of them gone now it seems; I suspect because people found out the same thing I did, that it's just not that useful and that the novelty wears off after the first 5 times you wave your hand over a reader and have a led go on or a dialog pop up on a screen.

I went to a piercing study, girl stamped a hole in the upper layers of my skin, made a small cut to open it up a bit further, slid in the ampule (which had been autoclaved first of course). Band aid on it, done. It was strange being in a studio with a bunch of people with facial tattoos and horn implants and discs the size of my wrist in their ears - and them looking at me like I was a freak from out of space. I do have to say though that I had to search around a bit to find someone willing to do it. There are plenty of places that will take your money to suspend you from their ceiling with flesh hooks in your back, but that won't stick a glass pill under your skin. Go figure.

You can also buy kits online if you want to DIY - basically big needle guns that are used to tag cattle which you just jam into your hand and pull the trigger on, literally. That would've been a bit too hard core for me, tbh.

Million dollar startup idea: Luggage with a faraday cage built into the lining.

Within reason, I think hotels expect a certain level of loss. They are probably not going to want to make a big scene in the lobby as a guest is departing and demand that they return the towel they are taking out.

On the other hand, theft by employees is something they are probably much more concerned about. Before this technology, you have to wonder how many hotel housekeepers had fully furnished their own homes with towels and bed linens at the expense of their employer.

What I want is RFID tags on all of my pieces of kit for when I go kayaking. Before I leave the house I scan my bag and see if I have missed anything. I was going to write a phone app to do it when I got a phone that had NFC, then I read up and found out the range was way too short.

Kayaker here too. The logistics pains of tour kayaking have too long gone unsolved, if you ever start working on this - give me a shout.

Wait, towels have RFID tags?! Never heard of that before.

The hotel probably uses a commercial laundry service. All the dirty towels go into a bin, and every few days a van from the laundry service delivers a pile of clean towels and takes away the bin of dirty towels. The bedsheets, pillow cases and duvet covers probably get the same treatment. You can get similar services for mechanics' overalls, door mats, chef's uniforms, and things like that. They'll even put the right…

That makes a lot of sense! Thanks.

If you carry a proximity card in your rear pocket, that's pretty much the same thing except that there's no surgery and it's easy to swap out or discard when no longer useful. Source: the door-opening sensors at my college, many years ago, were all located at the right height for a key in the back pocket to activate them. I referred to it as the "buttprint identification system".

They also have longer-range solutions now and things that use Bluetooth instead of rfid for this. Works from a few feet away. I'm guessing that it's using some combination of Bluetooth MAC + signal strength.

They do it for most pets now too. They're useful for identifying runaway pets wherever they end up, and for stuff like https://www.sureflap.com/en-us . I have a few of the sureflap doors and they work well for keeping my cats on their own diets (controlling access to a combination of crates + auto-feeders).

It's the same (exact?) thing as far as I'm aware; rice-sized glass bit with a tiny RFID chip inside.

alta ski area uses rfid intelligently -- embedded in lift tickets to forego scanning bottlenecks.

Solitude, Brighton and Snowbird also use the same tech. I know Solitude has had contactless lift ticket swiping in place for well over the past decade.

Also Squaw Valley in Tahoe. Ski passes are a great use for RFID! Their season passes are prox cards with a photo ID on them. Edit: they also work from 1-2 feet away. You just leave it in your pocket and walk through the gate.

It's also a lot easier to scan a bin of 100 RFID tags than it is to try to line up all of their barcodes :)

OK, the RSA conference failed here. They're supposed to be a security conference, yet they didn't use an RFID tag that's challenge/encrypt/response, so you can't clone it by passive listening. RSA itself used to make such things.

That tag is about the right level of security for towel inventory. The big win in this is managing outsourced laundry costs. Knowing how many items went to the laundry, and how many came back, rather than just counting linen carts, matters a lot. ABS Laundry Solutions overview (with ominous music) [1]
