... or you could get them here: http://www.tagstand.com/ for a third of the price and use an app that ties in with the existing profile infrastructure like tasker.
I used to be really sloppy at muting the phone at night and this cures that. My wife is a light sleeper and I can now make sure I am not waking her up at stupid o'clock in the morning when I get an email overnight.
I bought a bunch more tags from Tagstand and I am looking forward to finding more stuff to do with them.
Wouldnt a better UX be the sticker and my device are self aware of each other? I get a notification to check in upon passing the sticker and or an option to allow such notifications?
Though is the field of range between phone and sticker only a short distance as of now?
