TapFi is a mobile app that uses optical character recognition (OCR) via a device's camera to scan WiFi network details (SSID and password) from printed or handwritten cards and automatically connect the device to that network. It's interesting because it solves a common friction point in public spaces by eliminating manual password entry, though it relies on existing platform APIs rather than novel networking technology.
