* 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.
*
* 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.
