Ordinary card VS Chinese magic card
How to clone card to CUID card on Android?
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.
