RFID-RC552 и ардуино UNO

Мне нужно посмотреть что находится на карте. Читаю карту с помощью примера лежащего в библиотеке RC522. Но всё время выходит ошибка авторизации и даже UID не узнать. Подскажите как это сделать). С rfid стал баловаться недавно, много не знаю.

* ----------------------------------------------------------------------------
* 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.
*
* 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.
*
* 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:

* Reader/PCD Uno Mega Nano v3 Leonardo/Micro Pro Micro
* Signal Pin Pin Pin Pin Pin Pin

Ой, я только сейчас посмотрел
