Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• A Turkish translation can be found here, contributed by agyild.
• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

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):
