PhysicalWeb is the general concept of connecting physical devices to the web via BLE.

The core of the PhysicalWeb concept is based around the URI Beacon service. A URI Beacon is an unencrypted broadcast of a Universal Resource Indicator (URI), most commonly in the form of web links. This example is a more advanced form of the UriBeacon Example.

The PhysicalWeb concept is currently being championed by Google so the majority of the documentation is based around the [ https://github.com/google/physical-web | Google PhysicalWeb Github] page.

Here's an introduction to the concept.

There's an Android App to go with it.

As mentioned above, the UriBeacon Service is key to the implementation of PhysicalWeb. The UriBeacon documentation is based out of the Google UriBeacon Github page
