    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.

    Где код?Можно прочитать UID-номер карты.Больше ничего имеющимеся у Вас иструментами

    * ----------------------------------------------------------------------------
    * 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:

    Ой, я только сейчас посмотрел

    Какая карта?
    Возможно, алгоритм в скетче выводит базовую инфу и ничего не знает про структуру хранения данных на твоей карте.
