Could write, verified, still not working

Support
1

Hello guys,

Its pretty hard to find legit writable mifares, I sent back many until I found these round stickers that I could write on them.

The problem that after writing and verification they still wont work, wont open the door. The sensor flashing between red and green but stays red.

What could be the problem?

Some systems can detect Gen1a magic cards, do you have a gen2 you could try?
I think emulating would also work to check

You might also post a dump of the original and the clone, if you want some more sets of eyes to double check for discrepancies or oddities

Oh silly me, I just realize i wrote [+] ATQA: 00 04 instead of 0400.

I rewrote it but now it died on me:

[+] Valid ISO 14443-A tag found

“Card doesn’t support standard iso14443-3 anticollision“

Does it mean the tag is dead?
