Earlier this year Amazon announced that they were developing Dash – and it’s available now. It's a dedicated “order me” button that attaches to surfaces. You press it, and it orders the item on its cover from Amazon Prime (see photo.)
The technology is getting cheap enough that these devices are selling for $5 to Prime members. Currently they offer 18 buttons for trash bags, paper towels, toilet paper, bottled water, Gatorade, Gerber formula, etc. – you can change the product within the brand, but they’re really designed for convenient re-ordering of products you regularly need to restock.
At home, we usually keep a common list of things to buy for the next time someone goes to the store, so we probably won’t be using these.
However, as the technology continues to mature and lower in cost, these might be useful in stockrooms, as annunciators / doorbells or remote-control buttons.
What other business value can you see for a simple, one-button device like this?
