About this app

This is the beta version of our Dangerous NFC app for Android. It will ensure your xNT has been protected against accidental locking or malicious attack. It does this by doing the following;

1) Analyze the tag to ensure it is set up in a standard configuration and assess risks

2) Conform the capability container to latest NFC standard (E1 12 6D 00)

3) Lock the capability container against accidental or malicious modification

4) Freeze static and dynamic lock bytes on the tag, locking user memory pages in a permanent read/write state

5) Set non-default password and password acknowledgement bytes to user defined password

6) Write protect configuration bytes against accidental or malicious modification using password protection

The app does not yet do any of the following;

- Write protect any of the user memory contents, only configuration bytes are protected

- Unlock the tag or disable the password

- Write any data to the tag (for now use NXP's TagWriter app for this)

Change Log:
v1.0.3 - updated copy on main screen
v1.0.2 - alternate keyboard compatibility fix
v1.0.1 - bug fix
v1.0 - initial release

I'm a bit confused, what is done should be possible to undone, as well as setting with this app, standard NFC tools app cannot remove the password from tag (even if it's correct) and this app doesn't support any undoing of what it has done... I think that this should be the very 1st thing you should implement in this app... (I don't have implant but I'm planing to purchase it very VERY soon) - tomorrow 😁👍
