cool idea.
it's connect all things of the world.
but I have an idea, it's about the sensor.
you said 'This sensor can identify any customer in a physical store without Bluetooth, Wi-Fi or GPS protocols, and is completely seamless and frictionless.',  can I understand the sensor is your company product or other something? it's need install to the thing? how to integrate?

I try it.

but the hit is no more available coin. I feel sad
