File under “why didn’t I think of this” — iron- and sew-on QR code patches. The patches (and stickers) are available from a company called stkr.it. In addition to creating the QR code, they’ll also host an audio or video file forever.

These fabric patches would be very useful on the bags & clothing of people who cannot tell others about themselves. Scenarios range from lost toddlers to dementia patients to autistic wanderers. The police or whoever found the lost person could then scan the patch and see a video or hear an audio of the emergency contact details. It would be useful to also include a description of the lost person or show the person in the video for confirmation.

Granted the information isn’t as easily accessible as an ID bracelet, but the option to include more detailed information is a valuable one.
