Can not read 7 or 10 bytes uid #16

I have mifare ultralight with 7byte uid. The software dont have the feature to read my RFID. Do someone here have the time to implement this feature?

Did anyone resolve this? i'm at 7 byte as well and only partial read.

I have a third party reader that read a card to a DB as 04 A3 C6 CA E2 61 80

I can use the RC512 with an adriuno UNO and read the card as 04 A3 C6 CA E2 61 80 (example and library here:https://randomnerdtutorials.com/security-access-using-mfrc522-rfid-reader-with-arduino/ )

I use your package and get the following read.

New card detected

tag type: 0x10 uid : 0x8804a3c6 Have i just been up too long? that hex isn't the same as the ones above?

Edit: Just noticing that it is a partial match

Overlap in 04 A3 C6 CA E2 61 80 but fails to collect the second half? also the 88 at the beginning doesn't show up on other readers.
