Eddystone (Google)

Eddystone (by Google) is a way for computers to communicate with other nearby devices. It uses radio signals that are sent out from one device and picked up by another device. For example, when you set up a new phone or laptop, it can send out an Eddystone signal that nearby devices can pick up and use to connect to it. This makes it easy for people to quickly exchange data, like Wi-Fi passwords or contact information, without having to manually type it in. Eddystone can also be used to detect nearby devices and to trigger events, like playing a certain song when you walk into a store.
