libnfc supports UUID writable cards and even has some dedicated tools for them.

However it doesn't work with some of the cards found on eBay that are even simpler to use. Sector 0 is unlocked and can be written without any additional commands. libnfc requires a small patch to get it working.

Following has been tested under ArchLinux with modified libnfc 1.5.1, mfoc 0.10.2 and a SCL3711 dongle.

Patch & recompile libnfc

The patch is fairly simple, open libnfc-1.5.1/utils/nfc-mfclassic.c and comment 2 lines (it was lines 384 and 385 for me):

	## Instructions to switch odroid over to external ssd
	# You shouldn’t see any errors when running this process, if you do. Stop immediately and ask me.

	# run lsblk to see all the hard drives. You should see a line starting with mmcblk0 and then 2 more underneath it with
	# mmcblk0p1 and mmcblk0p2. That’s the sd card disk and the sd card partitions. You’ll also see a line starting with
	# sda (and/or sdb if there are two usb drives). We want to use the sd* one.
	lsblk

	#pull out some of the values from lsblk so we can automate the rest of the script
	read new_partition new_drive mountpoint <<< `lsblk -e 179 -l -o NAME,PKNAME,FSTYPE,MOUNTPOINT \|grep 'vfat\s*/media/odroid' \| awk {'print $1" "$2" "$4'}`

	* Accept control commands via USB.

	* Commands start with '!' and end with '.'
	* Commands have three parts: action, pin, value: !AAPPVV.
	*
	* E.g. '!01p101.' is DigitalWrite, Pin1, value = 1

	* Note: This is currently very crude. Much improvement could be made.
	* I think the use of strncpy is eating a lot of memory. Refactor?

	Trying to run iTunes with Wine, i faced various problems. Here is a working solution how to install iTunes on Debian-based systems (in my case Linux Mint 18.1) - with support for the iTunes Store. Warning: Syncing i-devices is still not possible.
	When installing it with the playonlinux-"iTunes 12"-script, log in into the Store was not possible in my case. Wine showed the follwing error when trying to log in: SecurityContext failed with error 0x80090304

	1. Install current Wine version (2.0.1) directly from the winehq repository
	wget -nc https://dl.winehq.org/wine-builds/Release.key
	sudo apt-key add Release.key
	sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ xenial main'
	sudo apt-get update
	sudo apt-get install --install-recommends winehq-stable
	wine --version
