Investigating Mifare NFC cards with PN532 module and C.H.I.P
In this brief document i will attempt to explain how to setup your chip and pn532 NFC reader to poke around with NFc cars.
Setup
After flashing[1] your chip, first thing yo need to do is install libnfc by running command
apt-get install libnfc-bin
And add your NFC device
mkdir -p /etc/nfc/devices.d/ echo -e "name = \"PN532 board via UART\" \nconnstring = pn532_uart:/dev/ttyS0" > /etc/nfc/devices.d/pn532_uart.conf
Now you actually need to connect reader to chip. Check attached picture to see where to connect each pin.
If you did everything right, you should be able to detect the device by running
nfc-scan-device
Identifying cards
Using this command you can check if reader detects NFC card successfully
nfc-list
You can identify cards by returned ATQA/SENS_RES, SAK/SEL_RES and ATS[2] bytes or you can use this utility[3] to make it easier. Below you can see responses from ISIC card (non bank issued one).
