A simple banking system using clickable signs!

I've created a banking system in Minecraft so far, which allows you to withdraw and deposit your "money" (emeralds) from/into your scoreboard. All you need to have this mechanism work is use only 2 clickable signs and a villager with special NBT settings. You won't even build it with any redstone components such as redstone dust, buttons, or levers!

For more details, check out my project page and download the world save, and you'll enjoy it! Curious about how to actually do it? A tutorial post is coming soon and will be available in my blog posts!

The following image shows what the banking system looks like in this project:
