Method 1:APDU command ffca000000 read uidAcr122u APDU command> 04 76 BF E1 BF 02 80 90 00
Method 2: Because the UID of the Mifare ultralight card is in the first page and second page of the card, we can directly read You can retrieve one page 2 data. Acr122u read page > 04 76 BF 45 90 00 > Data read at start page 00 > Number of bytes read: 04 > Hex mode: 04 76 BF 45 Acr122u read page > E1 BF
