I'm intrigued to see that the readers (as shown) (http://techcrunch.com/2012/05/11/tagstand-is-nfc-enabling-a-...) appear to be Arduino boards, with what looks like an Adafruit NFC/RFID breakout board (https://www.adafruit.com/products/364) and a mini-breadboard bare-wired to another IC.

Two questions:

* Are the readers going to be in enclosures on the night?

* Are you looking for a developer with Arduino (and some Android) experience? :)
