Credit Card Dumps and Magnetic Stripe Definition Explained
In a financial credit card dumps there are 3 types of tracks where the information is stored in the magnetic stripe for industry use. These is what hackers calls DUMPS.
TRACK 1 LAYOUT
Track 1 is coded with DEC SIXBIT and the ODD Parity method.
The information is stored in different formats that goes from A to M.
The “A” is only used by the bank itself, so you don’t to take much attention to this letter.
The “B” is where the holder’s financial information is stored, the most important section of the magnetic stripe.
C to M, is used for the ANSI Subcommittee X3B10.
N to Z, is the information that is available for use of individual card issuers.
Here you can see how it looks like:
Let’s go fast and easy:
- % for Start Sentinel
- B for Bank Type Credit Card
- 5XXXXXXXXXXXXXX2 for the Primary Account Number, in most cases this is the number printed on the front of the card, but not always.
- ^ is the separator
- GEORGENULL would be the the Holder’s last name
- / is the separator
- MAX the first name
- ^ Again another separator
- 11 Expiry Year, 03 Expiry Month
- 101 the Service Code
- 000000001000000003000000 the Discretionary Data
- ? is the end.
So, now that you already know how the information is stored in Track 1 and the letter containers, you should already figured out that the Track 1&2 are the vital tracks and the Track 3 is useless. The credit card dumps are mainly the first 2 tracks.
