[solved]Mifare classic SNOOP or SNIFF?

1) Can anyone tell me briefly the difference between SNOOP and SNIFF Mifare classic?
I want to find the key between the card and the reader.
[solved]

2) Can you simply sniff without using a PC?
Can Proxmark set up Sniff mode with PC, turn Proxmark off, sniff out keys using PowerBank, go home to PC, turn Proxmark on, read stored data from Porxmark?

I read a lot on the forum, but the more I read I have bigger chaos.
Thank you.

------
Have you done the check on which blocks is encrypted ?

Have you tried nested attack ? yes and work (stop) / yes and not work (go down)
Have you tried hardnest attack ? yes and work (stop) / yes and not work (go down)
Have you tried the crapto method (sniffing) ? Where the trace ? (dont get caught doing this) just an easy piece of advice.

I don't think so for this. Wait for someone to answer this.

Hope this helps.

@Dot.Com: Thank you for answering my question # 1.
Now I'm dealing with this problem with my Mifare Snoop. http://www.proxmark.org/forum/viewtopic … 115#p29115
Maybe you have this experience.

Re: [solved]Mifare classic SNOOP or SNIFF?

Sniff / Snoop is the same functionality but is used intermixed in the pm3 client.  Confusing yes,  and some of the sniff/snoop commands work bad.

When using it,  its all about finding the sweetspot for the pm3 antenna  between  card / reader.   Use hf list for some of the sniff/snoop to get the communication.   For  HF SNOOP,  you will need to look at data plot.
