Hardware Hacking with Your Rails App
summary
Project shows a Rails web app driving cheap terminals: an all‑in‑one PC boots Ubuntu into Chromium kiosk mode or an Electron wrapper that injects a header token, protecting the menu page. Chip cards use a TWN reader flashed via the vendor’s App Blaster firmware so the device acts as a USB keyboard with carriage return, letting Rails autofocused input capture IDs. Remote fixes use reverse SSH tunneling to the terminals; Raspberry Pi units handle pickup confirmations and auto‑power/reboot from BIOS.
