many thanks Biniek, I think you together with others that using FTK is a good approach.
Here are some regex examples for Track 1 and Track 2 by brand for mag-stripe data sets.
Track1
"B6011[0-9]\{12\}"
"B5[1-5][0-9]\{14\}"
"B3[47][0-9]\{13\}"
"B4[0-9]\{12\}[0-9]\{3\}"
Track 2
"6011[0-9]\{12\}=[01][0-9]\{3,3\}"
"5[1-5][0-9]\{14\}=[01][0-9]\{3,3\}"
"3[47][0-9]\{13\}=[01][0-9]\{3,3\}"
"4[0-9]\{12\}[0-9]\{3\}=[01][0-9]\{3,3\}"
Track 1
\%?B[0-9 ]{12,19}\^[^\^]+\/[^\^]+\^[0-9]{7,7}[^\?]+\.?
Track 2
\;?[0-9]{12,19}[\=][0-9]{12,32}\.?
Hope this helps or points you in the direction you need.

Credit card numbers should be pretty easy to pick off
AMX starts with 3
Visa Starts with 4
Mastercards start with 5
Discover cards start with 6
Usually the cards will have the first 4 or 8 numbers the same depending on which bank issues the cards. What I mean is that you and I have Chase visa cards and they should both start 4246-3151XXXX-XXXX This carries over to the other cards also.
