Do you have an unusual luggage tag?
Or do you tie a brightly colored cloth or ribbon on your handle to help find your luggage easily?
I made a bright removable cover for one of my suitcases a few years ago and I’ve always been able to identify it immediately when traveling.
My carry-on luggage needed a special ID tag and I just happened to get a very personalized one.
I found the “medical device” clip art on-line for one side.
Then I made my own QR code with my contact info on the other side. So my identity is kind of protected. One just needs a QR reader app to actually read it. (Of course a real QR Code doesn’t have a big blank circle in the middle of it…)
