Be cautious that some parts of a Mifare Classic memory are used for r/w access
of the rest of the memory, so please read the tag documentation before experimenting too much!
The 'u' option allows writing of special Mifare cards that can be 'unlocked' to allow block 0
The 'W' option allows writing of special Mifare cards that can be 'unlocked' to allow block 0
to be overwritten. This includes UID and manufacturer data. Take care when amending UIDs to set
the correct BCC (UID checksum). Currently only 4 byte UIDs are supported.
Similarly, the 'R' option allows an 'unlocked' read. This bypasses authentication and allows
reading of the Key A and Key B data regardless of ACLs.
*** Note that 'W' and 'R' options only work on special versions of Mifare 1K cards (Chinese clones).
