Does anyone really use this??? If so, how? I'm just not sure I understand it. I know you can get tags/stickers and then your phone will read them. Thing is, I figure if you have more than 2 or 3 tags, then by the time you go through your stickers for the app you want to control, you could just do it with the phone. Is this the app that eventually you can use your phone like a credit/debit etc rather than having to pull your card out of your purse/wallet (or both if you're a lady like me). I just want a 10 minute video on it on you tube and I'm no smarter about it than I was before. To me, its more stuff to keep track of. Now you carry your phone and your sticker/tags etc. I want things to make less things I have to keep track of. Am I missing the point somehow?
