very simple bro and you gonna see is logic
take a pos terminal in a dda know country = making most card dda mean having dda pos & ATM
put your shimmer inside or your malware
take a dda card and a sda card ok (electron are sda for sure)
next we make a transaction of 1 dollar with 1 card and same with the other card
we repeat it 2 time so what we see = 1 card data change and 1 card data dont change
i mean data use for transaction like arqc, etc
so you see after third transaction that the sda card dont change data because is static
so we talk of a pos in a dda country but if we take the same 2 cards and do it in a pos SDA, the 2 card become static...because of the reader
so we understand that with a shimmer in a big store or atm we can process a lot of card and see it fast, now one method to know it in advance
would be to first found all bin by bank of electron card......
other thing to take in case is that you need to have the last 20 transactions in your dump emv
other thing emv and magnetic track have 3 different number
first you have to read a transaction apdu to understand what happened
i put here a pdf very instructing about how to take the problem, you have to use sim card technologie and to change mean config the band rate.

read good that pdf and you gonna learn a lot
depend on card you use and country you use is making changing rules, but is not 100 solution
other thing to take care of is that you have the offline transaction
things are more possible offline, but amount are restricted by bank and stores, etc

sorry to look like mixed, maybe is make confuse but read the pdf first and you would see
after you make first read during transaction, we can continu
peace
