Walmart’s costly experiment
The Chicago Tribune reported that Walmart has ended its Mobile Scan & Go program, which it had running in around 150 locations. Mobile Scan & Go allowed shoppers to scan and pay using a handheld device or smartphone. There are a few things we don’t get: why are such experiments run in 150 stores rather than one, and why didn't the people in charge see that asking customers to weigh and tag their purchases before scanning them was far-fetched. In our view, the fact that certain technologies exist doesn’t mean that they always make sense in a retail business.
