Free, as in beer: KegDroid uses NFC and Xoom tablet to dispense on-tap beer
You have a tablet. You have an NFC enabled device. You have a thirst for anything awesome (read as: beer). So, what do you do? Well, if you’re Google employee Paul Carriff, you’d probably respond with something along the lines of “make a beer dispenser”.
Paul has taken a Motorola Xoom tablet and combined an Ardunio board to make this totally awesome beer dispenser, seen above. The way it works is simple. You have an NFC tag that literally cards you, as your age is built into the tag. You scan, and the dispenser gives it out, in perfectly defined increments. The Xoom even verifies that the beer is kept at an icy, refreshing 39 degrees Fahrenheit.
