Emulating ABA Track 2 using ATA5577
Hello,
We would like to emulate the open format ABA Track 2 - that has a facility code and a user code - using ATA5577.
If anyone has the mapping - block 0 and following blocks - that would be very helpful !
Thanks a lot.

Re: Emulating ABA Track 2 using ATA5577
if i read you correctly, you are attempting to emulate a magnetic stripe format on a prox card? what reader/software will be interpreting the data? i am unfamiliar with a "Standard" prox format for this application.

Hi,
It is actually an Indala open format called 4038. We have them as clamshells.
We would like to make a combo card with DEsfire and the ATA emulating the clamshell in order not to change the parking access system that works with the clamshell.
Clearer ? 
Thanks a lot.

Re: Emulating ABA Track 2 using ATA5577
much. I am not familiar with that format (maybe someone else here is...) but being indala it is likely the same block 0 config as the Indala 26-bit w (40134) format at http://www.proxmark.org/forum/viewtopic.php?id=1767.
But Indala formats typically have a scramble pattern to the bits so identifying the following blocks may be difficult.
but with enough samples it can be done.
do you have any traces of existing cards (along with the printed number on the tag)?

Re: Emulating ABA Track 2 using ATA5577
I have been said that nothing is scrambled on this one. I must admit that I'm today without any proxmark device around, so I can't send you traces. I feel bad :-(
So either someone has done it already - but looking to the summary you sent, I can"t find it - either I buy a new device and I work seriously on this.
Makes sens

Re: Emulating ABA Track 2 using ATA5577

john, some brands of readers output ABA when particular bits in their respective formats are flipped to a 1.
