My husband was handicapped and I would not recommend a wrist wallet at all. This will be an area that she will watch now and then, when her full attention should be on her cane or walker. Better still would be a vest with inside pockets, or a fanny pack she can wear in front, with a stiffened top so it will remain open when she unzips/unbuttons/opens the top, but with velcro so it stays closed when she wants it to. Or maybe one she can wear around her neck like a necklace, long enough so she can see it when it is opened, but with that easy to close velcro.
