This talk introduces the what, how and why.\n\nSIMtrace2 is an incremental step to SIMtrace.  On the outset, it looks like a minimal change: Simply replace the SAM7S with a SAM3S microcontroller.  However, due to the completely different CPU core architecture, the firmware was re-written from scratch. SAM3S supports more USB endpoints, so we can finally have a proper way of talking to card-reader and phone in parallel, paving the ground for card-emulation and man-in-the-middle.","original_language":"eng","persons":["Kevin
