			=== Basic working principles of Mifare Classic card ===
			Both, ISIC and Estonian transportation cards are working on Mifare Classic chip. Bank cards use another chip which is able to emulate Mifare Classic. SEB uses Mifare Plus and Swedbank uses JCOP as far as i know.

			Mifare classic`s memory is organized in 16 sectors of 4 blocks. One block contains 16 bytes.

==== 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[https://flash.getchip.com/] 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</code>

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
