HOW TO DECRYPT DUMP (TUTORIAL)

[Friend]

The topic itself is as old as the world but I believe that this information should be on every self-respecting card board, so let's get started.

So, our map dump consists of three tracks. We will write only the first two on the card, since the third is used in discount cards and affiliate programs, and is empty on bank cards in 90% of cases.

By purchasing a dump from the seller, we get a set of symbols of the following type (colors for clarity):

4483430123456789 = 1406101156780000

At first glance, just a set of numbers, but it can tell us a lot

1) The first digit gives us information about the payment system. So, the number 3 means that we have an American Express card, 4 - Visa, 5 - Mastercard, 6 - Discover

2) The first 6 digits highlighted in red - BIN, gives us information about the bank that issued the card, its type (credit or debit) and category (classic, gold, platinum and many other options).

In this example, I specifically took an existing bin so that you can see the information yourself, for example, here: http://www.binlist.net

3) All together 16 digits before the equal sign form the card number, the same one on the front side

4) The "=" sign does not carry any information, just a separating character

5) The first 4 digits after the equal sign are the expiration date of the card, in the year / month format. Our card is valid until June 2014.

6) Then comes the service code of the card, three characters, but a lot of information.

The first number defines where the card can be used:

0 - reserved for future use
1 - for international use
2 - for international use, with restrictions
3 - reserved for future use
4 - Reserved for future use
5 - for internal use only, except for pre-negotiated agreements
6 - for internal use only, except for pre-negotiated agreements, with restrictions
7 - not for payment, except for pre-agreed agreements
8 - Reserved for future use
9 - to check

The second digit defines the terms of use and authorization of the card:

0 - transactions are carried out according to standard rules
1 - reserved for future use
2 - the transaction is carried out by the emitter, must be online
3 - reserved for future use
4 - the transaction is carried out by the emitter, must be online, except for pre-agreed agreements
5 - reserved for future use
6 - reserved for future use
7 - reserved for future use
8 - Reserved for future use
9 - Reserved for future use

The third digit identifies the services and conditions of the PIN requirement:

0 - unlimited, PIN required
1 - no limits
2 - goods and services (not cash)
3 - ATM only and PIN required
4 - only money
5 - goods and services (not cash), PIN required
6 - unlimited, PIN on demand
7 - goods and services (not cash), PIN on demand
8 - reserved for future use
9 - Reserved for future use

7) Next comes infa directly for the bank, and it is essentially not important to us, but for general development: 1 - PVV availability code, 5678 - PVV code itself, 0000 - CVV / CVC code (not cvv2, namely cvv, now not used, usually there are just zeros)

Well, we've sorted out the second track. And now, using our map as an example, I will show how the first one will get from the second track without any sites / generator programs.

So,
1) Take the second track
4483430123456789 = 1406101156780000

2) Add the Latin B in front (says that our card is a bank card)
B4483430123456789 = 1406101156780000

3) Instead of "=", insert the construction "^ LASTNAME / FIRSTNAME ^". I will insert mine for example, you can write any (^ UNEMBOSSED / NAME ^ if the card is not named)

B4483430123456789 ^ MADISON / DANIEL ^ 1406101156780000

4) Add 6 zeros at the end
B4483430123456789 ^ MADISON / DANIEL ^ 1406101156780000000000

And voila, our first track is ready to be recorded on the card.

Finally, I want to say: do not confuse cards, write a visa for a visa, and a mastercard for a mastercard.

Take care of yourself and good luck in business.
