App randomly opens for any NFC capable card

[danielrozenberg]

For example if put my credit card next to my phone, the app opens with a popup saying "Invalid response"

I think it would be better to ignore cards that aren't recognized instead of opening that dialog.

(Ideally I would prefer to have an option to only scan for cards when the activity is visible)

Cautious +1 to this - I definitely like not having to open the app to scan a card, and I definitely like being able to scan unknown card types and see the raw data. But if unsupported cards (like credit cards) can be ignored, that would be a nice improvement.

Perhaps it could ignore cards that it's never scanned before, unless you have the app open or something.

This is fixed in the upcoming release.
