And by the way, $1USD is about a day's wage in most parts of the world. The tags, I can get as low as $0.10 and whi h can be provisioned and used without a phone.

Don't get me wrong, I take security very seriously, but in certain parts of the world, you can't even carry a phone with you, much less have the updated gear to read a smart card.
