I want to rise the distance of the proxmark when I'm snooping an exchange between a mi fare card and a reader.
How can I do that ?
Is it enough to rise the alimentation of the card by using a battery ? but what is the maximum voltage ? or maybe there is another solutions ?
Thanks for your help

4/ Do you know how to simulate this recorded exchange with the proxmark ?
Thanks a lot

]]>I am trying to sniff an exchange between a MiFare Card (a badge) and its reader.
It's RFID so I use the HF antenna with the proxmark3.
After I type in the proxmark3 command line : "hf mf sniff",
but It detects absolutely nothing...
I think it's not a distance problem because I put the HF antenna between the reader and the badge.
I know that the exchange between the badge and the reader is made because the reader 's Led become red (bad badge for this door).
I know that the antenna is OK because I can read the badge easily with the command "hf mf dump".
Somebody can help me please ?
Thanks a lot
looking forward to your reply,
Poly.
