Hi Melvin, are you sure you are using T=0 when talking to the card? simtrace2 (sniffing as well as cardem) only implements the T=0 protocol so far, as in the SIM card world, there is no need for other protocols like T=1.
If your card/reader are using T=1, then this would certainly explain why you don't get any output. > Can simtrace2 be used to trace any arbitrary T0 card communication or > is it somehow limited to SIM card APDUs ? It can trace any communication using T=0, there is no constraint on the type of APDU/TPDU used. -- - Harald Welte <lafo...@osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
