I only know of 4 reliable stores that sell dump + pin.
One of them is on this forum, you can find his contacts at this link:
101 dump is very similar to 201 dump, but the difference is that 201 dump asks for compliance with the card chip, that is, it cannot be used without writing the appropriate chip.
In order to write a blank card with a chip, it is necessary to use the appropriate software that can generate and create it correctly.
101 dump can be written with pin and use it successfully.
201 dump can be recorded with a pin, but if the blank of the magnetic card is without pins, it is necessary to write the authorization for chip emulation, so that when you put this card in a pos-terminal or ATM, he would receive the answer that the chip is present, although in fact it will not be. There are sellers of such software on private forums.
Therefore, it is easiest to work with 101 dump + pin or 101 dump without pin. But then the difficulty will arise that not all ATMs and pos-terminals will accept it for processing.
You can also just buy Java card blanks, which already come with a chip, and write 101 or 201 dumps on them. When recording, it is necessary to generate a chip card key in the EMV software (detailed guides on how to correctly record track2 + pin are on this forum).
Yes, 101 and 201 US dumps without regional blocking will work well in Europe at certain types of ATMs and POS terminals.
Old models of bakery are hard to find, but many of them still work.
For example, my friends posted ads for the purchase of old models of ATMs at a high price, when representatives of various banks began to write to them, they simply asked where their ATM was located and whether it was connected to work. They asked for the exact address because they wanted to test it.
Thus, they found more than 30 ATMs, this number was quite enough for them to work.
Therefore, buy Java blanks that already come with a chip and you will avoid problems finding old ATM models.
