> Wearable cams can RECORD your PIN from 40 METRES
No they can't, wearables like Glass don't have an optical zoom. The article itself admits they only made it work 3m away with an iPhone.
Strap the 2x extender on the 60x zoom on my Sony (equivalent to something like 1.2m focal length on a 35mm IIRC) and I reckon you could stretch it to 100m; it's not exactly subtle though, and to do it in the real world you'd need an angle to see which keys are being pressed on the keypad - easy from 3m, not so much at 40m.
Give me access to Hubble (and a mod that lets it focus that close) and I can grab your PIN from space!

Oh, that explains it.
