As a follow-on to this, I accidentally discovered that eBags' Connected Luggage Tags, which had a QR code and RFID chip to allow someone to get contact info for you without printing it on a tag, are now just useless hunks of plastic. The URLs for the tags no longer work and the eBags app, which one had used to register the tags, no longer exists. I had about a half dozen of these and had been continuing to use them in the belief that they served as reasonable bag IDs. Not anymore!
