Physical Web

Physical Web is a Google's Internet of Things (IoT) via simple web-based API. Every object broadcasts its URL periodically via Bluetooth 4.0 Low Energy (BLE). There is both an Android and an iOS app available for download (both of which are open source) that will monitor for broadcast URL advertisement packets and present them to the user. Hardware hackers can evidently build their own smart objects using the RFduino, a diminutive microcontroller that runs on battery power and is Arduino-compatible.
