maybe because chip emv hacking is not based on track 2, but based on intercepted data during a transaction with a shimmer.
shimmer EMV based on SIM card bypass technologie like SIM REBEL....
using software to touch data transfer and reuse it with a gsm software with latency changed.
OSMOCOM SIM TRACE
SDA is static so can be reuse in a pos terminal SDA like in south america for exemple
Most electron card are SDA.......
Why is not working for all ? because of DDA
SDA = static data authentification
DDA = dinamic data authentification
OSMOCOM SIM TRACE is open source and is use as server/client for APDU
PM me if you want to talk more on the subject....
