Unless you actually plan to encrypt emails, using this on a mobile device for 2 factor is irrelevant. Using another major brand does this: Login in once with NFC and it is always and forever in the Android phone unless you delete the key or something. So no need to reenter password and reuse key to login to email, etc. Anyone with access to phone can access it. So why spend money on hardware upgrade etc to develop this with NFC? Most people NEVER encrypt their email, and use these mainly for the initial 2 factor auth, which makes the phone a trusted device and prevents someone from logging in to your email from elsewhere.
