 * --------------------------------------------------------------------------------------------------------------------
 * Example to test your firmware.
 * --------------------------------------------------------------------------------------------------------------------
 * This is a MFRC522 library example; for further details and other examples see: https://github.com/OSSLibraries/Arduino_MFRC522v2
 * 
 * This example test the firmware of your MFRC522 reader module, only known version can be checked. If the test passed
 * it do not mean that your module is faultless! Some modules have bad or broken antennas or the PICC is broken.
