   A while back, I came across the open-source program below that'll skim NFC data using two Android phones. I don't have a NFC card yet(let alone EMV) because my card expires later this year, so I haven't been able to test this program out. The program itself does compile and run though
   
   https://sourceforge.net/projects/nfcproxy/
   
   Does anyone know what kind of data passes during an NFC transaction? Is it track1+track2 data, or is it something else?
