Business Insider reports that Walmart has decided to drop a mobile application that “let shoppers scan and pay for items with their smartphones so they could skip waiting in line at checkout registers.”

The reason? Walmart said that “not many customers were actually using the technology.”

According to the story, “The decision to drop the app, called Scan & Go, comes just four months after the retailer announced it would expand its test of the technology to more than 100 stores … The company said it would use what it learned from the Scan & Go test to inform other ongoing tests, such as Check Out With Me, a new service that arms Walmart employees with mobile checkout devices.”

KC's View: I guess that one of the questions is, are there certain retailers that have customers more likely to embrace technology, and others with shoppers that won’t?
