We were trying to find a name that would be somehow related to the technical functioning of the device (you know, nerds...)

We started from the frequency at which NFC operates, which is 13.56 MHz, but thirteen-fifty-six was a bit too long. So then we did the inverse (which is the wavelength) and it turned out to be around 22 meters.

22 is also 21 + 1, which is kind of cool and on top of this there's also a personal reason which makes 22 a special number for me.

So we just decided to go with it
