Not really in the spirit of the forum.
I have no issues if people give you "likes" if you provide something of value to them; my issue is in requesting "likes" in the promise of getting a fix, that may or may not come.

Re: Defective NFC tags. Penalty is possible?
I am sorry, I didn't get what you has wrote.
You can only do check for blocks reading, it's not fixeble.
If more deep usually it's broken a signal amlifer, the card memory is not damaged.
Seems this is the singal overscale effect, when cooficent of ampliffer going less then 0 and revert polarity. Equals the card has didn't understand 10100110 at all.
