 '''
 Simple Pyscan NFC / MiFare Classic Example
-Copyright (c) 2020, Pycom Limited.
+Copyright (c) 2019, Pycom Limited.
 
-This example runs the NFC discovery loop in a thread.
-If a card is detected it will read the UID and compare it to VALID_CARDS
-RGB LED is BLUE while waiting for card,
-GREEN if card is valid, RED if card is invalid
+This example continuously sends a REQA for ISO14443A card type
+If a card is discovered, it will read the UID
+If DECODE_CARD = True, will attempt to authenticate with CARDkey
+If authentication succeeds will attempt to read sectors from the card
