But it's cheap!

For $1 more you can get about 50x more security
Which is perfectly fine. I can layer that all back in when the time is right. The goal is accessibility first - enable someone's crappy Android phone to send and receive payments, first.
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.
