As a parent of a small child with glasses, yes a product like this, as a very tiny sticker, would be critical for many things, toddler's glasses cost $700 plus tax and there are so many expensive and difficult to replace medical items that children and patients of all ages lose constantly, (orthotics, arm braces, teeth retainers, dentures) and they lose them most often when in hospital, or in a nursing home, or school. Yes I understand you are interested in B2B only, but, as I sit here in my living room, I am surrounded by 13 different items that send out Bluetooth signals. It's doable. And when my did lose the first pair of $700 glasses--it was in a park. I spent hours carefully going back and forth, dividing the place into grids, on my hands and knees before giving up. May I suggest you talk to companies that manufacture glasses? Or online retailers like www.zennioptical.com Or popular children's label manufacturer www.MabelsLabels.com Which would allow consumers to buy them, and dear God then I could track the irreplaceable priceless, stuffies my child cannot lose. If you are not a parent, I realize that you won't understand, but I am telling you, nursing homes and daycare sales alone could make you a billion dollars. Somehow, hearing aids have microscopic Bluetooth inside and it has utterly changed that industry, but they don't make them as tiny stickers. Tiles are too large, and don't stick. Best of luck--and if you can't do consumer sales, can someone else on this thread please do it! :)
