proxEntry - Help to decode
Hi all,
I've encountered another 125Khz card that has once again stumbled me.
It looks like a EM plot, but again i'm not able to decode it.
I have tried using askdemod 0, mandemod 32, but doesn't work.
Anybody care to help?

Re: proxEntry - Help to decode
Looks like an EM4100, probably can't decode it as the Manchester Demodulation routine is broken, I believe others are aware and are working on it; you could try reverting to an old version of the svn? might fix your decoding problems?

Try this: http://www.sendspace.com/file/mnacq2
I got to stop using filedropper. it deletes the file after a while.

Re: proxEntry - Help to decode
interesting... It is definitely not a EM4xxx format. did you try the Hitag reader options? I read on their site they use Hitag as well as the T557x chips. I've never seen a plot quite like that though. and there is no apparent repeating pattern. it almost looks like it is an authentication string, (which would mean it is neither Hitag nor T557x).

Re: proxEntry - Help to decode
could you take a second read and post it just to rule out a bad read?

Re: proxEntry - Help to decode
Here is another one
http://www.sendspace.com/file/s0sg69
done with
lf read h
data sample 16000
I believe the readings are correct. I was worried that it is Hitag as well. I did read up about it in google, and most of the links points back to this forum, in which nobody has really cracked it yet.
