  3. Example sketch/program showing how to read data from more than one PICC to serial.
  4. --------------------------------------------------------------------------------------------------------------------
  5. This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid

  7. Example sketch/program showing how to read data from more than one PICC (that is: a RFID Tag or Card) using a
  8. MFRC522 based RFID Reader on the Arduino SPI interface.
  9.  
  10. Warning: This may not work! Multiple devices at one SPI are difficult and cause many trouble!! Engineering skill
  11. and knowledge are required!
