* MFRC522 - Library to use ARDUINO RFID MODULE KIT 13.56 MHZ WITH TAGS SPI W AND R BY COOQROBOT.
* The library file MFRC522.h has a wealth of useful info. Please read it.
* The functions are documented in MFRC522.cpp.
* ----------------------------------------------------------------------------
* 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. Please read it.
*
* Based on code Dr.Leong ( WWW.B2CQSHOP.COM )
* Created by Miguel Balboa (circuitito.com), Jan, 2012.
* Rewritten by Søren Thing Andersen (access.thing.dk), fall of 2013 (Translation to English, refactored, comments, anti collision, cascade levels.)
* Released into the public domain.
* ----------------------------------------------------------------------------
* 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.

* Pin layout should be as follows:
* Signal Pin Pin Pin
* Arduino Uno Arduino Mega MFRC522 board
* 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.
*
* If your reader supports it, this sketch/program will read all the PICCs
* presented (that is: multiple tag reading). So if you stack two or more
* PICCs on top of each other and present them to the reader, it will first
* output all details of the first and then the next PICC. Note that this
* may take some time as all data blocks are dumped, so keep the PICCs at
* reading distance until complete.
*
* Typical pin layout used:
* ------------------------------------------------------------
* Reset 9 5 RST
* SPI SS 10 53 SDA
* SPI MOSI 11 51 MOSI
* SPI MISO 12 50 MISO
* SPI SCK 13 52 SCK
*
* The reader can be found on eBay for around 5 dollars. Search for "mf-rc522" on ebay.com.
* MFRC522 Arduino Arduino Arduino
* Reader/PCD Uno Mega Nano v3
* Signal Pin Pin Pin Pin
* ------------------------------------------------------------
* RST/Reset RST 9 5 D9
* SPI SS SDA(SS) 10 53 D10
* SPI MOSI MOSI 11 / ICSP-4 51 D11
* SPI MISO MISO 12 / ICSP-1 50 D12
* SPI SCK SCK 13 / ICSP-3 52 D13
