The idea behind this app is to allow for you to test multiple copies of NFC's at once as a bulk test
When starting the app you are greeted by a select file option where you choose the playlist you wanna run.
All the playlists should be placed in ext/apps_data/nfc_playlist and an example of how the data in the file should look can be found below.
/ext/nfc/link.nfc
/ext/nfc/link2.nfc
An example file can be found in the repository
This app was design, built and tested using the Xtreme firmware i don't see why it wont work with other firmwares but do keep this in mind when building it with FBT/uFBT
