hf se against iclass

Hi, I have some weird issue. Couple of days ago I flashed my proxmark with Iceman's fork. Everything was fine until I wanted to use "hf se" on my iclass card. This command works like on 1/50 attempts. This very same card was recognized 100% of the time before flashing the firmware. I can't belive that this behaviour is caused by flashing FW, because I returned to previous one and there is the same problem.

It happens only for:
Mem: 16 KBits/16 App Areas (255 * 8 bytes) [1F]

Always works for:
Mem: 2 KBits/2 App Areas (31 * 8 bytes) [1F]

Any idea?

Ok, I noticed, that my company started to change our access control system cards. They're look the same as the old one, but Proxmark can't recognize them. Are there any new iclass cards, that aren't even recognizable by Proxmark?

Can you explain what do you mean by saying this?

Maybe Seos? Not sure if that has been added yet...

What are the markings? iClass, iClass SE? Also what symbol does the serial number start with *, +, = ?

Re: hf se against iclass

I can't see the markings, since this side of a card is covered by some labels. But I'm guessing that the serial number start with +

Btw. what make those types card so diffucult to even read the CSN?
