Hardcoded CARD_WIDTH

CARD_WIDTH should be computed dynamically.

Adding banks from different country

Hello, it does not read some cards in Turkey with nfc. How can I solve this? Can you help me how do I change the code structure?

Some cards receive information, some do not.

Scanning card bricks history

Hello,
If i scan my bank card, it renders the history unusable.

The history looks empty, says "No history find" and under "Scan history" some Chinese characters appear:

Strangely, if i go into settings and delete data, i can see that the records are still there: right now it says "Record count: 7".

So something happens when reading certain cards that bricks NFSee's ability to display history.

Remove unavailable technological data

There are two types of data that should not be shown:

1. The displayed technique data should match the type of the card.
2. Some data items are not available on iOS

Use the phone as a NFC card

Since the app has all the information regarding the card, why not use it as one?

Instead of carrying many cards, it would be nice to just take my phone loaded with all of them.

APP UI lags on high refresh rate screen

It seems that this has a refresh rate less than 60hz on a 120hz screen. You can see a conspicuous delay after your finger slipping on it and it is leaving streaks or trails.

Allow to export card data to file or clipboard

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.

Add monochrome icon

Please support the Themed Icon.

Thanks.

May needs adapt to Android 12

I can add my campus card normally, but unable to use it due to the system does not opening the nfsee app when I swipe it. I looked into the NFC settings and found that nfsee app was not recognized correctly, so unable to set it default, moreover unable to use the app function normally.

Keys

There is a list of well-known keys in Mifare Classic Tools (https://github.com/ikarus23/MifareClassicTool/tree/master/Mifare%20Classic%20Tool/app/src/main/assets/key-files). Would you add them into nfsee?
