It seems a little bit like something from a retro-futurist’s dream: Tell a small handheld device your grocery list, and it’ll go ahead and prepare an order that will be delivered to your door. It sounds a little like a smartphone, but it isn’t: It’s Amazon Dash, a new way to order groceries through Amazon Fresh. Amazon Dash is about the size of a remote control, and it features both a microphone and a barcode scanner, which allows you to either speak the name of the item you need or scan the barcodes for whatever you need.
