@ -426,6 +426,12 @@ Note: it seems some cards only accept the "change UID" command.
It accepts direct read of block0 (and only block0) without prior auth.
Writing to block 0 has some side-effects:
* It changes also the UID. Changing the UID *does not* change block 0.
* ATQA and SAK bytes are automatically replaced by fixed values.
* On 4-byte UID cards, BCC byte is automatically corrected.
### Characteristics
* UID: 4b and 7b versions
