really cool? yes. Impractical? probably?

Scanning earth using satellites is really cool. Maybe they're outsourcing this to a central company, and paying a hundred bucks per store per month. fine. But to be honest, there are some more effective low tech ways to catch these numbers, for example by looking at the number of transactions, or installing sensors on every entrance to count the number of people entering.

Seems like they're shooting a pigeon with a cannon.
