I’ve just pushed Hass NFC 1.1.3 to the store. There now is a cancel button for the fingerprint authentication.
Also starting tomorrow (25th of December) I will have a sale until the end of the year. The app will then cost 0.99USD instead of 1.99USD. For those on the fence of using the app this might be welcome.
The sale is also to thank everyone helping me with testing and giving ideas. Have a great Christmas and new year!
