Allow to export card data to file or clipboard #17

luisschwab commented 1 year ago

It would be very nice to be able to export data encoded on the card to a file, or even copy it to the clipboard.

Copying unique ID's is easy enough, but I have cards encoded with over 100 lines of JSON. Pretty much makes it impossible to work with the data.

The problem with exporting data is that different types of tags have different data on them. While it is straghtforward to generate a JSON clip (in fact we use JSON to pass data around, which you can see in read.js), it is not easy to come up with a general abstraction / data format.

maybe just allow for copy paste on each field then?

So... I came here looking for the same thing. My solution for now was: Create a backup of the app data over ADB -> decompress the backup -> view the sqlite database. For a temporary solution we could just export the data ROW. It's JSON and it's a way of sharing the dumps.

For the time being, I have created a small script, that downloads app data. Just run it like this ./dump_app_data.sh im.nfc.nfsee and you will find the app data.
