Amazon introduce ‘Internet of Things’ button that you can connect to anything 

For example, you can click the button to unlock or start a car, open your garage door, call a cab, call your spouse or a customer service representative, track the use of common household chores, medications or products, or remotely control your home appliances.

Amazon have launched an AWS IoT Button. Just like the Amazon Dash button it’s based on it’s only available in the U.S. and connects to your Wi-Fi network.

They’re a neat idea, the Dash buttons are branded and re-order the product they’re assigned to whenever you click the button. Now, with the Button you can hook that click into anything you like.
