alt Hacker News> Clothes? maybe RFID patches that are unobtrusive.
Decathlon and Zara both have RFID tags in their products.

https://www.inditex.com/itxcomweb/so/en/press/news-detail/7f... (Inditex is the parent company of Zara. Link is a press release from 2014.)
So if one were to buy all their clothes at Decathlon (clothes for sports and other outdoor activities) and Zara (everyday wear as well as fancier clothing), and found a reader that can read the RFID tags they use, one would save the time needed to add RFID tags to one’s clothes ;)
There might be other stores that have RFID tags on all of their products too. I only mention these two in particular because I have purchased products from both of them using their RFID-based self-checkout in their stores and thus seen it first-hand.
However, I am not sure if all of the products have the RFID label embedded in the actual fabric or if some or most have the RFID label attached to paper labels that you’d remove before using the clothes. So that would also need to be determined before deciding to replace one’s whole wardrobe with clothes exclusively from these stores.

Almost all retail RFID tags are on hanging labels, like with the price, or a sticker on the item. Although I did find one inside a pillow once.
A huge number of items at Walmart, Kohls, Target, Academy, Old Navy, and many other stores now (those are just the ones I've seen in store.)
Look for the 'EPC' logo, GS1 is the same standards body that controls the UPC barcode numbering.

Though - you don't want to use those types for this application, they are too long distance / not selective enough, and the readers are expensive.
Buy a big pack of NFC stickers instead, or print up some QR codes.
A friend of mine used to once a year hang all his shirts with the open end of the cloth hangers' hooks facing forward. After wearing and washing them he'd hang them back with the hanger facing the other way. After a year he'd toss out any shirts that were still facing the original way and had thus not been worn.
