Went back and watched that video, love 'not just bikes', those instore scanners are a really good idea, Costlesworthdi should have all employed these by now.

The only reason i can think they haven't is the same reason i'd assume for independents and IGA's the cost. Without knowing anymore about the costs, i'd assume its a mix of upfront payments for the scanners, etc, and a, out of proportion, per transaction clip of the ticket for 'maintenance and service costs', just like the bank cards have.

I love what you're suggesting though, use QR codes on each product so customers use the hardware in their pockets to scan out their items as they go.

It would reduce those upfront costs so much, and could be done with less memory bloat like the Maccas type apps. If this doesn't already exist we should round up some of the more tech focused users/mods/admins on aussiezone and do it ourselves, then use the revenue from that as an ongoing fund for the benefit of 'aussiezone' as Australia's Social Web alternative. Lets do this!
