> FWIU RFID cost has been a major limiting factor in supply chain traceability; pallet-level RFID is almost affordable? But I guess that depends on the type of RFID tag, isn't it? For example, Decathlon already introduces tags with UUIDs with every single product they sell (even the cheapest socks), and they use them to inventory tracking and to scan your cart when you buy in store. https://www.cisper.nl/en/case-studies/rfid-case-study-decathlon-uses-tageos-rfid-labels-to-identify-millions-of-items-worldwide https://www.cisper.nl/en/case-studies/rfid-case-study-decath... Of course, although business-wise practical, that can pose a security issue... You can track peoples clothes on the wild! https://mastodon.social/@russss/102674489508219187 https://mastodon.social/@russss/102674489508219187

Is it the link between the Invoice and the ~serialNumber of the scannable-at-a-distance Product? Most barcodes today only encode a ~sku (and not a serial number). Minimally, to lookup additional product information from just an sku (similar to a shorturl app), consumers would need an API to retrieve and/or lookup from a conjunction of per-Organization named graph documents linking schema:Things' ~schema:identifiers with the RDF subject URIs of NutritionInformation records. - P: schema:nutrition - d: MenuItem,Recipe - r: NutritionInformation - C: NutritionInformation https://schema.org/NutritionInformation https://schema.org/NutritionInformation C: https://schema.org/Offer https://schema.org/Offer supersedes the GoodRelations vocabulary for Products and Services: > For GTIN-related fields, see Check Digit calculator and validation guide from GS1.

  I just checked one of the electronic invoices I had in my email, and for every line (be it a protein bar or a jacket) it includes an "RFID" field with what I guess it's the serial number contained in the tag. I don't have a reader for that frequency so I can't really confirm. Edit: An example for some chocolate cereal bars: Barrita cereales Chocolate x10 Talla única Ref: 2610768 RFID: 003869592404 That'd be for this product: https://www.decathlon.es/es/p/barrita-de-cereales-clak-con-chocolate-ecosize-10-x-21-g/_/R-p-304214?mc=8518622 https://www.decathlon.es/es/p/barrita-de-cereales-clak-con-c...

Very interesting. Thank you for sharing. I would have not thought per unit tracking was practical. The RFID wiki article agrees with my long held assumption of $0.05-0.25 per. (Caveat: My RFID knowledge is circa 2005, so very out of date.) From a super quick skim reading, it looks like Decathlon uses Tageos. They come in a roll, so certainly could be a lot cheaper than $0.05. https://www.cisper.nl/en/tageos-eos-300-impinj-m730-54x34-mm-paper-sticker https://www.cisper.nl/en/tageos-eos-300-impinj-m730-54x34-mm... https://www.cisper.nl/datasheets/tageos/Tageos_Datasheet_EOS-300-M730-54x34-paper-sticker-3000000117.pdf https://www.cisper.nl/datasheets/tageos/Tageos_Datasheet_EOS... It appears Tageos is using aluminum foil as the conductor for RFID UHF. No surprise there. So if PulpaTronics can ship non-metal RFID, I think they'd still be competitive.

  Don't know exactly which exact model is decathlon using (once I get home I'll see if any of my equipment still has its tags attached), but I found tags at less than ten cents buying 5000 units rolls from a random US distributor [0]. So being French both Decathlon and Tageos, and with the volume they must buy, no doubt they can get to 5 cents or so. Not using metal, I guess Pulpatronics could also do local factories more easily, needing "only" paper (and lasers). Easier to do JIT production or smaller batches I imagine. 0: https://www.barcodefactory.com/tageos/rfid-labels/eos-241/o184c01x309003

FWIW Thermal labels last from 2-35 years depending on the thermal printer and the label. There are thermal cable labels that wrap around e.g. ethernet cables
