Hi Felix,
Yes, each UID is unique. But I would NOT use the UID as criteria for identify a dedicated user! A UID can be easily manipulated.
For a MIFARE Ultralight EV1 I would write user information in the user memory space and protect the memory with a password. So, the reader must authenticate to the card and if this is successful, the card data can be read and identify the user.
