Some time ago I received a ring with an embedded NTAG 213 Type 2. It's been a couple years now. But this ring has been through hell and back. Picked up the ring and tapped it with this app running. Could be do to its age or lack of use for awhile it seemed not to read. However after a few epic battles of "find the sweet spot" it worked great. Utilizing this software she was laid bare for me to enjoy. Great software, easy to use, flows so nice, and jamed packed with features.

This is the only Android app currently known to me that supports and interprets the NFC Forum NDEF Signature Record Type v2.0. The UI is simple but well done and without all the "bells and whistles".

Saving xml export is impossible and sending files to email doesn't work at all. When you click save scan it sometimes says it saved other times just spams a error message until you force quit the app. When you share to email it will open the email app and insert the title of the email but it fails to attach any files. It is impossible to find the xml files in your phones file browser probably because they are storedwhere you cannot view them and they give you no option to change save directory.
