Hello! As you know, a dump consists of two tracks. There are also Track 3, but now Track 3 in credit cards is practically not used.
For our work, only Track 2 is important to us.
Many carders know only 101 and 201 service code. They know that 101 code is a dump without a chip and without a pin. 201 dump with a chip
and without a pin.
What to do with the rest of the dumps, many do not know. But there are many other dumps. There are 121,126,206,220,221,226,521,606,620 dumps
and many others that are great for our business))
Today I will give you information that will help you understand this issue.
