Dot.Com: does this card ignore the access bits? So if block0 is set to read only can it be overwritten?
From the auction picture #2 I see that the magic backdoor is not in place, however there are cards that just ignore wrong access bits or even wrong keys.

Block 0 is able to be overwritten for sure. I tested it out personally. Magic backdoor is in place. If you need to test the card, you can teamviewer me and try the card using my proxmark.

Re: Looking for 7byte UID mifare 1k writable cards

I got my hands on one of these 7b Magic UID tags.
It seems like its a Generation2 tag. It doesn't answer to backdoor commands.  This should indicate that it can be used by the NFC phones.
