2. The default password of the card is 12F, FFFFFFFFFFFF.
3. CUID supports mobile phone NFC android App MCT to modify UID. (The MCT of some mobile phones is unstable and may cause writing failure. Generally, we still recommend using an RFID reader for reading and writing)

The difference between UID card and CUID card.
UID card:
Ordinary copy cards can repeatedly erase and write all sectors. They are mainly used for IC card copying. They will fail when encountering card readers with firewalls.
CUID card:
The erasable and anti-shielding card can repeatedly erase and write all sectors. It can be used when the UID card copy is invalid and can bypass the firewall.

Note: Ordinary 13.56mhz rfid reader cannot write to CUID card!
