The Physical Web: building on top of the open web
summary
Physical Web broadcasts URLs from devices so phones pull up pages on demand using a 31‑byte BLE packet (about 18 usable bytes) and often a redirector like URL shorteners (tiny.cc) to change destinations or carry sensor data. Demos show a parking‑meter payment using WebSockets, a toy driven by Web Bluetooth joystick, and Android/Chrome/Opera support plus a proxy spam filter. Coin‑cell beacons last years on Nordic/Arm chips, a fat‑beacon pattern fetches pages on click, and a scanning API arrives soon.
