I have an elechouse PN532 v4 board. I 've written code to communicate with various cards, including payment (visa/master). Now I'm trying to develop ePassport reading app, but if I run a nfc-poll that comes with libnfc it doesn't detect my card. The ePassport reading app on my android phone reads the cards without a problem. Any suggestions? Modulation/baud rate settings maybe wrong?..
