The ugly head of the Desktop Scanner rears again...
I didn't do a very exhaustive search but I am sure this idea has been broached before:
Would it be possible to manage inventory and perhaps charge portals from a "desktop" version of the scanner; a sort of extended version of intel.ingress.com – and I'll even let you have this one for free! – perhaps called scanner.ingress.com.
Maybe this could be a perk for players L8+, or even some higher access level?
Think on it.
