I will say this is a cool project. However, the implementation of the idea in reality is even worse than NFC. While NFC is useful in many contexts, it then requires you to put a faraday cage around your card and manually turn on or off the NFC to not get your money stolen, and even then can be circumvented. Even further relaxing the distance constraints even makes it even easier to steal money. I'd imagine a lot of the engineering would go into making it safe (having some set up such that the US sounds vary to some degree...then may be even an authentication protocol..then...then...then...
The moment I saw the headline, I was incredulous. The actual project implementation in the article is a rather cool hack, so props to the author. I dread the day someone actually picks this up, assuming someone does actually choose to.
