So my mother, who has Alzheimer's, and is still v mobile (although she's given up on driving and we've sold the car, thank goodness), is starting to get lost a little more. I'm looking at GPS trackers, with the intention of hiding one in her handbag that she takes everywhere. But stitching it into her handbag would obviously make it difficult to charge, and not stitching it in would seem a recipe for it to get lost. Any tips on hidden trackers?
