Is this the only evidence of working ncash available? I'm trying to be excited about this project but I can't help feeling slightly underwhelmed.

I would have thought that the team at Nucleus Vision would have posted plenty of working examples on their YouTube account by now, as they claim to have the tech working in 10 stores in India. They clearly spent a bit of time and money on the promo vid. Where's the proof of the working tech (aside from this 1 vid)?
