By the end of January 2018, 125 Walmart locations will feature “Scan & Go” technology, which enables shoppers to scan items and pay for their purchases directly from their phones while in-store. Upon departure from the store, shoppers simply present a digital receipt to a greeter.

Why it’s important: This technology digitizes and dematerializes shopping lines, human cashiers and cash registers. Considering grocery chain Kroger’s “Scan, Bag, Go” technology, which will be rolled out to 400 stores this year, and Amazon’s Go concept store, we’re rapidly heading toward an era of all-digital shopping transactions.
