If used as dumps, can you use a 220 piece just like a 201 ? Will it have more security or is it basically the same thing since it is not an online purchase ( but a store purchase )

Most of the time 201 is a CREDIT card and 220 is a DEBIT card

Okay thanks

Will it have more security ?

The security is about the same, its just different types of cards

i didnt know that! thanks
