+# FlipperZero_NFC_Playlist:
 The idea behind this app is to allow for you to test multiple copies of NFC's at once as a bulk test
 
 At the moment this project is very basic and just reads the cards from the txt file and emulates the NFC's but this is very early days of development and i wanted to make a basic version of my idea first
@@ -8,6 +8,10 @@ When you start the app there is a start button when pressed starts the playlist
 
 To set the playlist you need to create a file in ext/apps_data/nfc_playlist called playlist.txt you can find an example of the file in the repository
 
+## Know problems:
+- Unable to press any buttons while emulating as they are unresponsive and if you spam them it crashes the app
+- Emulating UI can be a bit janky not displaying as intended 100% of the time
+
 ## TODO:
 - [x] Add basic UI
 - [X] Add checks for files that are not NFC and missing file and add a display for them
