I just ordered my NFC ring and can't wait to get it. I am happy it will unlock my NFS based Android phone (Nexus 5), which is worth the purchase alone, but after seeing Apple's keynote and seeing how easy their NFC based payment system is because of Touch ID, I can't see why this ring can't be used for Google Wallet authentication as well. Is this something that would be hard to implement? I think it would be very convenient not to have to do anything but touch my phone to the terminal then touch my ring to the phone to authorize the payment. Just as easy as Apple's Touch ID solution.
