What a boring way to cheat. He should have done it James bond style, (or Lock Stock style), with a little radio transmitter and piezo-electric device that can tap out patterns on your upper thigh, then have someone in the audience (or watching via binoculars, or via TV, or tiny camera), relaying a computer's move to you remotely.
I could build a fully self-contained device that I could hide on my person for under $100, and have it connect via 3G. Cheaper than an iPhone, and you don't have to get up and go to the bathroom after every move.
... If it wasn't for those re-usable filters. Saving money, and keeping plastic K-cups out of landfills is a great part of it, sure. The real reason is that my favourite locally-roasted coffee just isn't available in K-cup format. I rarely want to brew a whole pot, and like the convenience of not having to constantly clean a press.
Needless to say I will not be buying one of their new brewers, unless I can use my own coffee.
Actually a 4-digit password only has 6,561 possible combinations, whereas a fingerprint is close to infinite, since it's really comparing sections of a large bitmap.
What's more likely is that someone will find a way to fool the fingerprint scanner-- with an object (mold/photo/gel/etc), by hacking how the scanner communicates with the device, or by breaking the software on the device itself.
