--------------------------------------------------------------------------------------------------------------------
Example sketch/program showing how to read data from a PICC to serial.
--------------------------------------------------------------------------------------------------------------------
This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid
Example sketch/program showing how to read data from a PICC (that is: a RFID Tag or Card) using a MFRC522 based RFID
Reader on the Arduino SPI interface.
When the Arduino and the MFRC522 module are connected (see the pin layout below), load this sketch into Arduino IDE
then verify/compile and upload it. To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When
you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output
will show the ID/UID, type and any data blocks it can read. Note: you may see "Timeout in communication" messages
when removing the PICC from reading distance too early.
@license Released into the public domain.
