Hi,
I have uploaded the same code to NodeMCU and got This error
error

The board is perfectly working with SPI protocol. No Problem with the board.

@sriharshamvs @paulmassen @arozcan
I also have the same problem. Maybe it's because even though the Mifare chip supports SPI, I2C, and UART, if you’re using the most common breakout board (RFID-RC522), it’s hard wired to only support SPI.

Yes, most of these boards only support SPI unless you cut some connections. Here is a thread on how to turn on the I2C mode. https://forum.arduino.cc/index.php?topic=442750.0
