+ * ----------------------------------------------------------------------------
+ * This is a MFRC522 library example; see https://github.com/miguelbalboa/rfid
+ * for further details and other examples.
+ * 
+ * NOTE: The library file MFRC522.h has a lot of useful info. The functions are
+ * documented in MFRC522.cpp. Please read it.
+ * 
+ * Released into the public domain.
+ * ----------------------------------------------------------------------------
+ * Example sketch/program showing how to test your firmware.
