Not really, I have one of mine stuck to a little stand on my bedside table, so it is in contact all night with the tag, but it doesn't re-read the tag over and over - once it does it's thing, it's done. The one on my bike only glitches when I hit a bump or the phone is allowed to momentarily lose intimate contact with the tag, then re-acquires it.
I would think inside a case it would be tight to the phone and work as you wish. When I get my next batch I'll give it a try. Being jostled in a bookbag might be an issue, but I'm betting it would work.
