How to clone card to CUID card?

The block 0 of the CUID card is changeable, so you just need to write block 0 or full dump to the CUID card with the NFC device.

If the BCC byte or SAK byte is invalid, MTools will not write block 0 to prevent damaging the card.

How to clone card to UID card and UFUID card?

Both the UID card and UFUID card has backdoor command, so you can use PN532, ACR122U or Proxmark 3 to write dump back to data without keyA or keyB.

Command line to write dump file:

    nfc-mfclassic W a u card.mfd

Command line to change UID:
