# barcode-utils
Collection of tools for our beverage POS kiosk system with barcode scanner:
## barcode-websocket-server
Service that binds to the USBHID barcode scanner and provides scan events via a websocket to web clients.
Can also wake the screen via ydotool.
## webextension-tabfocus
Web Extension that injects a `window.extension_tabfocus()` function into browser tabs' Javscript context.
When called, this function will cause the browser to switch to the calling tab.
