Different ID for MFRC522 and USB Reade

[matze1708]

Hello all,
I used on a Pi the MFRC522 module with the SimpleMFRC522 library.
I read there the same RFID tag I get the number: 962106709424

With a USB reader (YARONGTECH) I get the number: 1426522848

Is there another conversion in the library? E.g. from a HEX value to a natural number?

How can I make both devices output the same?

Thank you

Same here. Code is not really usable that way
