-This script will try to dump the contents of a Mifare TNP3xxx card.
-It will need a valid KeyA in order to find the other keys and decode the card.
+This script will try to load a binary datadump of a Mifare TNP3xxx card.
+It vill try to validate all checksums and view some information stored in the dump
+For an experimental mode, it tries to manipulate some data.
+At last it sends all data to the PM3 device memory where it can be used in the command  "hf mf sim"
